2 SafetyPlease read this information before using your ultrasound system. Itapplies to the ultrasound system, transducers, recording devices, and any optionalequipment.This section covers general safety information only. Safety informationthat applies only to a specific task is included in the procedure for that task.

This device is intended for use by, or by the order of, and under the supervisionof a licensed physician qualified to direct the use of the device.

A WARNING describes precautions necessary to prevent injury or loss of life.

A CAUTION describes precautions necessary to protect the equipment.

Electrical SafetyThis equipment has been verified by a recognized third-party testing agency as aClass I device with Type BF and Type CF isolated patient-applied parts. (The safetystandards met by this system are included in the system User Reference.) For max-imum safety observe these warnings:

WARNINGS• Shock hazards may exist if this system, including all externally mounted

recording and monitoring devices, is not properly grounded. Protectionagainst electrical shock is provided by grounding the chassis with a three-wirecable and plug. The system must be plugged into a grounded outlet. Thegrounding wire must not be removed or defeated.

• Do not remove the protective covers on the system; hazardous voltages arepresent inside. Cabinet panels must be in place while the system is in use. Allinternal adjustments and replacements must be made by a qualified PhilipsUltrasound field service engineer.

• Do not operate this system in the presence of flammable gases or anesthetics.Explosion can result.

• To avoid risk of electrical shock hazards, always inspect the transducer beforeuse: Check the face, housing, and cable before use. Do not use if the face iscracked, chipped, or torn, the housing is damaged, or the cable is abraded.

WARNINGS• To avoid risk of electrical shock hazards, always turn off the system and dis-

connect it from the wall outlet prior to cleaning the system.

• All patient contact devices, such as transducers, pencil probes, and ECG leadsmust be removed from patient contact prior to application of a high voltagedefibrillation pulse.

• Connection of optional devices not supplied by Philips Ultrasound couldresult in electrical shock. When such optional devices are connected to yourultrasound system, ensure that the total system earth leakage current doesnot exceed 300 µA.

• To avoid risk of electrical shock, do not use any transducer that has beenimmersed beyond the specified cleaning or disinfection level. See the "Disin-fectants and Gels" section.

• To avoid risks of electrical shock and fire hazards, inspect the system powercord and plug on a regular basis. Ensure that they are not damaged in any way.

CAUTIONS• Although your system has been manufactured in compliance with existing

EMI/EMC requirements, use of this system in the presence of an electromag-netic field can cause momentary degradation of the ultrasound image. If thisoccurs often, review the environment in which the system is being used, toidentify possible sources of radiated emissions. These emissions could be fromother electrical devices used within the same room or an adjacent room.Communication devices such as cellular phones and pagers can cause theseemissions. The existence of radio, TV, or microwave transmission equipmentlocated nearby can cause emissions. In cases where EMI is causing distur-bances, it may be necessary to relocate your system.

Safety

CAUTIONS• Electrostatic discharge (ESD), commonly referred to as a static shock, is a nat-

urally occurring phenomenon. ESD is most prevalent during conditions of lowhumidity, which can be caused by heating or air conditioning. During lowhumidity conditions, electrical charges naturally build up on individuals and cancreate static shocks. An ESD condition occurs when an individual with anelectrical energy build-up comes in contact with objects such as metal door-knobs, file cabinets, computer equipment, and even other individuals. Thestatic shock or ESD is a discharge of the electrical energy build-up from acharged individual to a lesser or non-charged individual or object. The level ofelectrical energy discharged from a system user or patient to the ultrasoundsystem can be significant enough to cause damage to the system or transduc-ers.

• The following precautions can help to reduce ESD: anti-static spray on car-pets; anti-static spray on linoleum; anti-static mats; or a ground wire connec-tion between the system and the patient table or bed.

Mechanical Safety

WARNINGS• Be aware of the casters, especially when moving the system. The system could

cause injury to you or others if it rolls over feet or into shins. Exercise cautionwhen going up or down ramps.

• When attempting to overcome an obstacle, do not push the system fromeither side with excessive force, which could cause the system to tip over.

• Position external hardcopy devices away from the system. Ensure that theyare secure. Do not stack them on the system.

• When positioning the articulated monitor, move it carefully to avoid pinchinghands or extremities against other objects, such as a bed rail.

• Never park the system on an incline.

• The brakes are intended as a convenience. To increase cart security, use wheelchocks when the system is parked.

• If the system behaves abnormally after moving or transporting it, contact Phil-ips Ultrasound Customer Service immediately. System components can with-stand considerable shock, but excessive shock can cause a system failure.

• Before moving the system, ensure that the keyboard is retracted, the controlpanel is centered, and the monitor is locked (see "Positioning the ControlModule" on page 98 and "Preparing and Moving" on page 84). Whenextended, the keyboard might be damaged if it hits another object, and thevideo monitor could swing out during transport, causing injury or equipmentdamage.

CAUTIONS• Ensure that the cables for all patient-applied parts are secure before moving

the system. Use the cable management system to ensure that transducercables are protected from damage.

• Do not roll the system over transducer cables or power cables.

Safety

Equipment ProtectionFollow these precautions to protect your system:

CAUTIONS• Excessive bending or twisting of cables on patient-applied parts may cause fail-

ure or intermittent operation of the system. Take care not to run over cableswith the system, which may damage them.

• Improper cleaning or sterilization of a patient-applied part may cause perma-nent damage. For cleaning and disinfection instructions, see the "Disinfectantsand Gels" section.

• Do not submerge the cables of patient-applied parts in solution. The cablesare not liquid-tight beyond the applied part/cable or cable/connector inter-faces.

• Do not use solvents such as thinner or benzine or abrasive cleaners on thesystem, transducers, or any hardcopy device.

• For optimal performance, your ultrasound system should be connected to acircuit dedicated solely for the ultrasound system.

• In general, only the area of the transducer acoustic window is watertight.Except where specified in specific transducer cleaning instructions, do notimmerse the remainder of a transducer in any liquid.

ALARA Education ProgramThe guiding principle for the use of diagnostic ultrasound is defined by the “as lowas reasonably achievable” (ALARA) principle. The decision as to what is reason-able has been left to the judgement and insight of qualified personnel. No set ofrules can be formulated that would be sufficiently complete to dictate the correctresponse to every circumstance. By keeping ultrasound exposure as low as possi-ble, while obtaining diagnostic images, users can minimize ultrasonic bioeffects.

Since the threshold for diagnostic ultrasound bioeffects is undetermined, it is thesonographer’s responsibility to control total energy transmitted into the patient.The sonographer must reconcile exposure time with diagnostic image quality. Toensure diagnostic image quality and limit exposure time, an ultrasound systemprovides controls that can be manipulated during the exam to optimize theresults of the exam.

The ability of the user to abide by the ALARA principle is important. Advances indiagnostic ultrasound not only in the technology but in the applications of thattechnology, have resulted in the need for more and better information to guidethe user. The output display indices are designed to provide that important infor-mation.

There are a number of variables which affect the way in which the output displayindices can be used to implement the ALARA principle. These variables includeindice values, body size, location of the bone relative to the focal point, attenua-tion in the body, and ultrasound exposure time. Exposure time is an especiallyuseful variable, because it is controlled by the user. The ability to limit the indexvalues over time supports the ALARA principle.

Applying ALARA

The system imaging mode used depends upon the information needed. 2D andM-mode imaging provide anatomical information, while Doppler, Philips ColorPower Angio (CPA), and Color imaging provide information about blood flow. Ascanned mode, like 2D, CPA, or Color, disperses or scatters the ultrasonic energyover an area, while an unscanned mode, like M-Mode or Doppler, concentratesultrasonic energy. Understanding the nature of the imaging mode being usedallows the sonographer to apply the ALARA principle with informed judgement.Additionally, the transducer frequency, system setup values, scanning techniques,and operator experience allow the sonographer to meet the definition of theALARA principle.

The decision as to the amount of acoustic output is, in the final analysis, up to thesystem operator. This decision must be based on the following factors: type ofpatient, type of exam, patient history, ease or difficulty of obtaining diagnosticallyuseful information, and the potential localized heating of the patient due to trans-ducer surface temperatures. Prudent use of the system occurs when patientexposure is limited to the lowest index reading for the shortest amount of timenecessary to achieve acceptable diagnostic results.

Although a high index reading does not mean that a bioeffect is actually occurring,a high index reading should be taken seriously. Every effort should be made toreduce the possible effects of a high index reading. Limiting exposure time is aneffective way to accomplish this goal.

Safety

There are several system controls that the operator can use to adjust the imagequality and limit the acoustic intensity. These controls are related to the tech-niques that an operator might use to implement ALARA. These controls can bedivided into three categories: direct, indirect, and receiver controls.

Direct Controls

Application selection and the Output Power control directly affect acousticintensity. There are different ranges of allowable intensity or output based onyour selection. Selecting the correct range of acoustic intensity for the applicationis one of the first things that occurs in any exam. For example, peripheral vascularintensity levels are not recommended for fetal exams. Some systems automati-cally select the proper range for a particular application, while others requiremanual selection. Ultimately, the user has the responsibility for proper clinical use.The ultrasound system provides both automatic (default) settings and manual(user-selectable) settings.

Output Power has direct impact on acoustic intensity. Once the application hasbeen established, the Output Power control can be used to increase ordecrease the intensity output. The Output Power control allows you to selectintensity levels less than the established maximum. Prudent use dictates that youselect the lowest output intensity that is consistent with good image quality.

Indirect Controls

The indirect controls are those that have an indirect effect on acoustic intensity.These controls affect imaging mode, pulse repetition frequency, focus depth, pulselength, and transducer selection.

The choice of imaging mode determines the nature of the ultrasound beam. 2D isa scanning mode, Doppler is a stationary or unscanned mode. A stationary ultra-sound beam concentrates energy in a single location. A moving or scanned ultra-sound beam disperses the energy over an area and the beam is concentrated onthe same area for a fraction of the time as that of an unscanned mode.

Pulse repetition frequency or rate refers to the number of ultrasound bursts ofenergy over a specific period of time. The higher the pulse repetition frequency,the more pulses of energy in a period of time. Several controls affect pulse repeti-tion frequency: focal depth, display depth, sample volume depth, flow optimiza-tion, scale, number of focal zones, and sector width controls.

Page 44: Iu22 Reference Manual

Safety

iU22 User Reference453561170891

Focus of the ultrasound beam affects the image resolution. To maintain orincrease resolution at a different focus requires a variation in output over thefocal zone. This variation of output is a function of system optimization. Differentexams require different focal depths. Setting the focus at the proper depthimproves the resolution of the structure of interest.

Pulse length is the time during which the ultrasonic burst is turned on. The longerthe pulse, the greater the time-average intensity value. The greater the time-aver-age intensity, the greater the likelihood of temperature increase and cavitation.Pulse length or burst length or pulse duration is the output pulse duration inpulsed Doppler. Increasing the Doppler sample volume size increases the pulselength.

Transducer selection indirectly affects intensity. Tissue attenuation changes withfrequency. The higher the transducer operating frequency, the greater the attenu-ation of the ultrasonic energy. A higher transducer operating frequency requiresmore output intensity to scan at a deeper depth. To scan deeper at the same out-put intensity, a lower transducer frequency is required. Using more gain and out-put beyond a point, without corresponding increases in image quality, can meanthat a lower frequency transducer is needed.

Receiver Controls

Receiver controls are used by the operator to improve image quality. These con-trols have no effect on output. Receiver controls only affect how the ultrasoundecho is received. These controls include gain, TGC, dynamic range, and imageprocessing. The important thing to remember, relative to output, is that receivercontrols should be optimized before output is increased. For example: beforeincreasing output, optimize gain to improve image quality.

An Example of Applying ALARA

An ultrasound scan of a patient’s liver begins with selecting the appropriate trans-ducer frequency. After selecting the transducer and the application, which arebased on patient anatomy, adjustments to output power should be made toensure that the lowest possible setting is used to acquire an image. After theimage is acquired, adjusting the focus of the transducer, and then increasing thereceiver gain to produce a uniform representation of the tissue follows. If an ade-quate image can be obtained with the increase in gain, then a decrease in output

Page 45: Iu22 Reference Manual

2

iU22 User Reference453561170891 45

Safety

should be made. Only after making these adjustments should you increase outputto the next level.

Having acquired the 2D display of the liver, Color can be used to localize bloodflow. As with the 2D image display, gain and image processing controls must beoptimized before increasing output.

Having localized the blood flow, use the Doppler controls to position the samplevolume over the vessel. Before increasing output, adjust velocity range or scaleand Doppler gain to obtain an optimal Doppler trace. Only if maximum Dopplergain does not create an acceptable image do you increase output.

In summary: select the correct transducer frequency and application for the job;start with a low output level; optimize the image using focus, receiver gain, andother imaging controls; if the image is not diagnostically useful at this point, thenincrease output.

Additional Considerations

Ensure that scanning time is kept to a minimum, and ensure that only medicallyrequired scanning is performed. Never compromise quality by rushing through anexam. A poor exam may require a follow-up, which ultimately increases exposuretime. Diagnostic ultrasound is an important tool in medicine, and, like any tool, itshould be used efficiently and effectively.

Output DisplayThe system output display comprises two basic indices: a mechanical index and athermal index. The thermal index further consists of the following indices: softtissue (TIS), bone (TIB), and cranial bone (TIC). One of these three thermal indi-ces will be displayed at all times. Which one depends upon the system preset oruser choice, depending upon the application at hand.

The mechanical index is continuously displayed over the range of 0.0 to 1.9, inincrements of 0.1.

The thermal index consists of the three indices, and only one of these is displayedat any one time. Each transducer application has a default selection that is appro-priate for that combination. The TIB, TIS, or TIC is continuously displayed overthe range of 0.0 to maximum output, based on the transducer and application, inincrements of 0.1.

The application-specific nature of the default setting is also an important factor ofindex behavior. A default setting is a system control state which is preset by themanufacturer or the operator. The system has default index settings for the trans-ducer application. The default settings are invoked automatically by the ultrasoundsystem when power is turned on, new patient data is entered into the systemdata base, or a change in application takes place. Figure 2-1 illustrates the imple-mentation of the output display.

Figure 2-1 On-Screen TI and MI

The decision as to which of the three thermal indices to display should be basedon the following criteria:

• Appropriate index for the application: TIS is used for imaging soft tissue, TIBfor a focus at or near bone, and TIC for imaging through bone near the sur-face, as in a cranial exam.

• Mitigating factors that might create artificially high or low thermal index read-ings: location of fluid or bone, or blood flow. For example, is there a highlyattenuating tissue path so that the actual potential for local zone heating is lessthan the thermal index displays.

• Scanned modes versus unscanned modes of operation affect the thermalindex. For scanned modes, heating tends to be near the surface; forunscanned modes, the potential for heating tends to be deeper in the focalzone.

• Always limit ultrasound exposure time. Do not rush the exam. Ensure thatthe indices are kept to a minimum and that exposure time is limited withoutcompromising diagnostic sensitivity.

Safety

Mechanical Index (MI) Display

Mechanical bioeffects are threshold phenomena that occur when a certain level ofoutput is exceeded. The threshold level varies, however, with the type of tissue.The potential for mechanical bioeffects varies with peak pressure and ultrasoundfrequency. The MI accounts for these two factors. The higher the MI value, thegreater the likelihood of mechanical bioeffects occurring. There is no specific MIvalue that means that a mechanical effect is actually occurring. The MI should beused as a guide for implementing the ALARA principle.

Thermal Index (TI) Displays

The TI informs the user about the conditions that exist that might lead to anincrease in temperature at the surface of the body, within the body tissue, or atthe point of focus of the ultrasound beam on bone. That is, the TI informs theuser of the potential for temperature rise in body tissue. It is an estimate of tem-perature increase in body tissue with specific properties. The actual amount ofany temperature rise is influenced by factors such as tissue type, vascularity, modeof operation and others. The TI should be used as a guide for implementing theALARA principle.

The bone thermal index (TIB) informs the user about potential heating at or nearthe focus after the ultrasound beam has passed through soft tissue or fluid, forexample, at or near second or third trimester fetal bone.

The cranial bone thermal index (TIC) informs the user about the potential heatingof bone at or near the surface, for example, cranial bone.

The soft tissue thermal index (TIS) informs the user about the potential for heat-ing within soft homogeneous tissue.

You can display TIS, TIC, or TIB by touching TI. TIC is displayed when you selecta transcranial application.

Mechanical and Thermal Indices Display Precision and Accuracy

The MI and TI precision is 0.1 unit on the system.

The MI and TI display accuracy estimates for the system are given in Acoustic Out-put Tables, on the user information CD. These accuracy estimates are based onthe variability range of transducers and systems, inherent acoustic output model-ing errors and measurement variability, as discussed below.

The displayed values should be interpreted as relative information to help the sys-tem operator achieve the ALARA principle through prudent use of the system.The values should not be interpreted as actual physical values in interrogated tis-sue or organs. The initial data that is used to support the output display is derivedfrom laboratory measurements based on the American Institute of Ultrasound inMedicine (AIUM) measurement standard. The measurements are then put intoalgorithms for calculating the displayed output values.

Many of the assumptions used in the process of measurement and calculation areconservative in nature. Over-estimation of actual in situ intensity exposure, forthe vast majority of tissue paths, is built into the measurement and calculationprocess. For example:

• The measured water tank values are derated using a conservative, industrystandard, attenuation coefficient of 0.3 dB/cm-MHz.

• Conservative values for tissue characteristics were selected for use in the TImodels. Conservative values for tissue or bone absorption rates, blood perfu-sion rates, blood heat capacity, and tissue thermal conductivity were selected.

• Steady State temperature rise is assumed in the industry standard TI models,and the assumption is made that the ultrasound transducer is held steady inone position long enough for steady state to be reached.

A number of factors are considered when estimating the accuracy of the displayedvalues: hardware variations, estimation algorithm accuracy, and measurementvariability. Variability among transducers and systems is a significant factor. Trans-ducer variability results from piezoelectric crystal efficiencies, process-relatedimpedance differences, and sensitive lens focusing parameter variations. Differ-ences in system pulser voltage control and efficiencies is also a contributor tovariability. There are inherent uncertainties in the algorithms used to estimateacoustic output values over the range of possible system operating conditions andpulser voltages. Inaccuracies in laboratory measurements are related to, amongothers, differences in hydrophone calibration and performance, positioning, align-ment, and digitization tolerances, and variability among test operators.

The conservative assumptions of the output estimation algorithms of linear prop-agation, at all depths, through a 0.3 dB/cm-MHz attenuative medium is not consid-ered in the accuracy estimate for the display. Neither linear propagation, noruniform attenuation at the 0.3 dB/cm-MHz rate, occur in water tank measure-ments or in most tissue paths in the body. In the body, different tissues and organs

Page 49: Iu22 Reference Manual

iU22 User Reference453561170891 49

Safety

have dissimilar attenuation characteristics. In water, there is almost no attenua-tion. In the body, and in particular, in water tank measurements, non-linear propa-gation and saturation losses occur as pulser voltages increase.

Therefore, the display accuracy estimates are based on the variability range oftransducers and systems, inherent acoustic output modeling errors, and measure-ment variability. Display accuracy estimates are not based on errors in, or causedby measuring according to, the AIUM measurement standards, or the effects ofnon-linear loss on the measured values.

Control Effects

Controls Affecting the Indices

As various system controls are adjusted, the TI and MI values may change. Thiswill be most apparent as the Output Power control is adjusted; however, othersystem controls will affect the on-screen output values.

Output Power

Output Power controls the system acoustic output. Two real-time output valuesare on the screen: a TI and MI. They change as the system responds to OutputPower adjustments.

In combined modes, such as simultaneous Color, 2D and pulsed-wave Doppler,the individual modes each add to the total TI. One mode will be the dominantcontributor to this total. The displayed MI will be from the mode with the largestpeak pressure.

2D Controls

Sector Width

Narrowing the sector angle may increase frame rate. This action will increase theTI. Pulser voltage may be automatically adjusted down with software controls tokeep the TI below the system maximums. A decrease in pulser voltage willdecrease MI.

Zoom

Increasing the zoom magnification by pressing Zoom may increase frame rate.This action will increase the TI. The number of focal zones may also increase

automatically to improve resolution. This action may change MI since the peakintensity can occur at a different depth.

Number of Focal Zones

More focal zones may change both the TI and MI by changing frame rate or focaldepth automatically. Lower frame rates decrease the TI. MI displayed will corre-spond to the zone with the largest peak intensity.

Focus

Changing the focal depth will change MI. Generally, higher MI values will occurwhen the focal depth is near the natural focus of the transducer.

Color and Power Controls

Flow Opt

Increasing the color sensitivity with the Flow Opt control may increase the TI.More time is spent scanning the color image. Color pulses are the dominant pulsetype in this mode.

Color Sector Width

Narrower color sector width will increase color frame rate and the TI willincrease. The system may automatically decrease pulser voltage to stay below thesystem maximum. A decrease in pulser voltage will decrease the MI. If pulsedDoppler is also enabled then pulsed Doppler will remain the dominant mode andthe TI change will be small.

Color Sector Depth

Deeper color sector depth may automatically decrease color frame rate or selecta new color focal zone or color pulse length. The TI will change due to the com-bination of these effects. Generally, the TI will decrease with increased color sec-tor depth. MI will correspond to the peak intensity of the dominant pulse typewhich is a color pulse. However, if pulsed Doppler is also enabled then pulsedDoppler will remain the dominant mode and the TI change will be small.

Safety

Scale

Using the scale control to increase the color velocity range may increase the TI.The system may automatically adjust pulser voltage to stay below the system max-imums. A decrease in pulser voltage will also decrease MI.

Sector Width

A narrower 2D sector width in Color imaging will increase color frame rate. TheTI will increase. MI will not change. If pulsed Doppler is also enabled, then pulsedDoppler will remain the dominant mode and the TI change will be small.

M-Mode and Doppler Controls

Simultaneous and Update Methods

Use of combination modes affects both the TI and MI through the combination ofpulse types. During simultaneous mode, the TI is additive. During duplex, the TIwill display the dominant pulse type. The displayed MI will be from the mode withthe largest peak pressure.

Sample Volume Depth

When Doppler sample volume depth is increased the Doppler PRF may automat-ically decrease. An increase in PRF will increase the TI. The system may also auto-matically decrease the pulser voltage to remain below the system maximum. Adecrease in pulser voltage will decrease MI.

Other

2D, Color, M-Mode, CPA, PW, and CW

When a new imaging mode is selected, both the TI and MI may change to defaultsettings. Each mode has a corresponding pulse repetition frequency and maximumintensity point. In combined or simultaneous modes, the TI is the sum of the con-tribution from the modes enabled and MI is the MI for the focal zone and modewith the largest derated intensity. The system will return to the previouslyselected state if a mode is turned off and then reselected.

Acoustic Output and MeasurementSince the initial use of diagnostic ultrasound, the possible human biological effects(bioeffects) from ultrasound exposure have been studied by various scientific andmedical institutions. In October 1987, the American Institute of Ultrasound inMedicine (AIUM) ratified a report prepared by its Bioeffects Committee (Bioef-fects Considerations for the Safety of Diagnostic Ultrasound, J Ultrasound Med.,Sept. 1988: Vol. 7, No. 9 Supplement), sometimes referred to as the StoweReport, which reviewed available data on possible effects of ultrasound exposure.Another report “Bioeffects and Safety of Diagnostic Ultrasound,” dated January28, 1993, provides more current information.

The acoustic output for this system has been measured and calculated in accor-dance with the “Acoustic Output Measurement Standard for Diagnostic Ultra-sound Equipment” (AIUM, NEMA 1998), the “Standard for Real-Time Display ofThermal and Mechanical Acoustic Output Indices on Diagnostic UltrasoundEquipment” (Revision 1, AIUM, NEMA 1998), and the September, 1997 FDA doc-ument “Information for Manufacturers Seeking Marketing Clearance of DiagnosticUltrasound Systems and Transducers.”

In Situ, Derated, and Water Value Intensities

All intensity parameters are measured in water. Since water absorbs very littleacoustic energy, these water measurements represent a worst case value. Biolog-ical tissue does absorb acoustic energy. The true value of the intensity at anypoint depends on the amount and type of tissue and the frequency of the ultra-sound that passes through the tissue. The intensity value in the tissue, In Situ, hasbeen estimated by using the following formula:

Page 54: Iu22 Reference Manual

Safety

iU22 User Reference453561170891

2

54

In Situ = Water [e-0.23alf]

Since the ultrasonic path during an examination is likely to pass through varyinglengths and types of tissue, it is difficult to estimate the true In Situ intensity. Anattenuation factor of 0.3 is used for general reporting purposes; therefore, the InSitu value which is commonly reported uses the formula:

In Situ derated = Water [e-0.069lf]

Since this value is not the true In Situ intensity, the term “derated” is used.

Mathematical derating of water based measurements using the 0.3 dB/cm-MHzcoefficient, may yield lower acoustic exposure values than would be measured in ahomogenous 0.3 dB/cm-MHz tissue. This is true because non-linearly propagatingacoustic energy waveforms experience more distortion, saturation, and absorp-tion in water than in tissue, where attenuation present all along the tissue pathwill dampen the buildup of non-linear effects.

Safety

The maximum derated and the maximum water values do not always occur at thesame operating conditions; therefore, the reported maximum water and deratedvalues may not be related by the In Situ (derated) formula. For example: amulti-zone array transducer that has maximum water value intensities in its deep-est zone also has the smallest derating factor in that zone. The same transducermay have its largest derated intensity in one of its shallowest focal zones.

Conclusions Regarding Tissue Models and Equipment Survey

Tissue models are necessary to estimate attenuation and acoustic exposure levelsIn Situ from measurements of acoustic output made in water. Presently, availablemodels may be limited in their accuracy because of varying tissue paths duringdiagnostic ultrasound exposures and uncertainties in acoustical properties of softtissues. No single tissue model is adequate for predicting exposures in all situa-tions from measurements made in water, and continued improvement and verifi-cation of these models is necessary for making exposure assessments for specificapplications.

A homogeneous tissue model with an attenuation coefficient of 0.3 dB/cm-MHzthroughout the beam path is commonly used when estimating exposure levels.The model is conservative in that it overestimates the In Situ acoustic exposurewhen the path between the transducer and the site of interest is composedentirely of soft tissue, because the attenuation coefficient of soft tissue is generallyhigher than 0.3 dB/cm-MHz. When the path contains significant amounts of fluid,as in many first and second-trimester pregnancies scanned transabdominally, thismodel may underestimate the In Situ acoustical exposure. The amount of under-estimation depends on each specific situation. For example, when the beam pathis longer than 3 cm and the propagation medium is predominantly fluid (condi-tions that may exist during transabdominal OB scans), a more accurate value forthe derating term is 0.1 dB/cm-MHz.

Fixed-path tissue models, in which soft tissue thickness is held constant, some-times are used to estimate In Situ acoustical exposures when the beam path islonger than 3 cm and consists largely of fluid. When this model is used to esti-mate maximum exposure to the fetus during transabdominal scans, a value of 1dB/MHz may be used during all trimesters.

The maximum acoustic output levels of diagnostic ultrasound devices extend overa broad range of values:

• Computed estimates of upper limits to temperature elevations during trans-abdominal scans were obtained in a survey of 1988 and 1990 pulsed Dopplerequipment. The vast majority of models yielded upper limits less than 1degree C and 4 degrees C for exposures of first-trimester fetal tissue and sec-ond-trimester fetal bone, respectively. The largest values obtained wereapproximately 1.5 degrees C for first-trimester fetal tissue and 7 degrees Cfor second-trimester fetal bone.

About Training Voice ProfilesTraining a voice profile involves reading text into the system using a voice controlheadset. The system lets you choose from among a number of books of text toread. Once you start the process, the system listens to your speech to associateeach written word with your pronunciation of it. As you read the text, the systemdisplays recognized text in green and unrecognized text in red.

If the system does not recognize one or more words, you can re-read some or allof the text on the page. When the system recognizes your reading of all text on apage, it displays the next page of text. It is not necessary that every word be rec-ognized by the system during training. If a few words are not recognized afterre-reading, you can skip to the next page by clicking Next.

If you need to stop the training before you are finished, you can click Suspend tosave your input, mark your place, and close the training window. When you openthe training window for your voice profile again, the system displays the text pageyou were working in when you suspended training.

Select a quiet location in which to train a voice profile. When reading duringtraining, speak in your normal tone of voice at your normal rate.

Creating and Training a Voice ProfileAlthough you can use voice control without creating a voice profile, your voicecommands are more accurately interpreted when you use a profile that you havetrained. Training a voice profile to a minimal level takes only about 2 minutes. Youcan further improve recognition accuracy by performing additional training (see"Doing Additional Training" on page 112).

NOTEWhen naming profiles, do not include single quotes or other special characters.

Before you begin creating and training a profile, read "About Training Voice Pro-files" on page 110.

NOTEThe Auto Log Off time shown on the User Settings display indicates how longthe system can be inactive before you are logged off automatically. Only the sys-tem administrator can change this setting.

Imaging DisplayThe imaging display contains an ultrasound image, exam and image information,and indicators (Figure 5-7).

The image area is located approximately in the center of the monitor screen. Tothe right of the image itself are a depth scale and a curve representing the TGCsettings. To the right of the TGC curve is a list of values for the sliders. A gray-scale bar or color bar is displayed to the right of the TGC curve. In M-mode andDoppler, the sweeping display appears below the 2D image.

Patient and exam data are displayed in the area directly above the ultrasoundimage. The system does not display patient data in this area until you start anexam. This area also includes the current time and date, the institution name, theselected transducer and clinical option, the TI setting and the TI and MI values.

Image information is displayed to the left of the image. In modes such as duplex ortriplex, additional image information is also displayed. Those additional parametersets can be displayed below the initial set and to the right of the image.

Using TransducersThe system includes three receptacles for array transducers and one receptaclefor a pulsed- or continuous-wave Doppler probe. All four receptacles can beoccupied at the same time, but only one transducer can be active at a time. Whena transducer is not in use, store it in one of the transducer holders on the controlmodule. Always use the cable management system to prevent cables from beingstepped on or run over by the cart wheels.

For information on transducer clinical options, maintenance, and artifacts, referto the "Transducers" section.

Connecting Transducers

➤ To connect a transducer

1. Set the transducer in one of the transducer holders on either side of the con-trol module.

2. Hang the transducer cable on the cable management bracket below the con-trol module.

3. Insert the transducer connector into one of the three receptacles on thefront of the system (Figure 5-8).

4. Turn the locking lever clockwise.

➤ To select a transducer

1. Press Transducer.

2. On the Transducer touch screen, touch a transducer button to select atransducer.

3. Touch the clinical option and preset you want to use. The touch screen closeswhen you make your selection.

Using ECGThe system can display a trace on the image representing an ECG signal. ECGinput can be either a low-level signal (from leads connected to the patient) or ahigh-level signal (from a patient monitor). Separate receptacles are used to con-nect low-level ECG and high-level ECG signals to the system. Heart rate, derivedfrom the ECG signal, is displayed on the screen whenever ECG is connected anddisplayed.

For information on using ECG, see "Physio (ECG)" on page 212.

Using the DVD Drive The system includes a digital versatile disc (DVD) drive, located next to the On/Standby switch. You can use this drive to store and transfer patient files, includingfull exams, 3D data sets, and reports. In addition, you can save, restore, and dis-tribute setups data, including Quick Save presets and voice profiles.

For additional information on specific applications of the DVD drive, refer to "Sys-tem Administration" on page 371 and "Sending Exams and Images" on page 311.

About Media CompatibilityDVD and CD media are available in a number of types. Not all media types arefully compatible with the system DVD drive. You can use the following mediatypes with the system:

• DVD+RW (rewriteable, 4.7 GB capacity)

• DVD+R (write once, 4.7 GB capacity)

• CD-R (write once, 650 MB capacity)

Page 149: Iu22 Reference Manual

iU22 User Reference453561170891 149

Using the System

The system supports multi-session writing to both DVD+RW and CD-R media.This means that you can record information onto these discs in multiple sessions,provided each session is closed before a new session begins. The system automat-ically closes an open session when you end an exam and when you click Eject inthe Patient Directory.

If you always use Eject in the Patient Directory when ejecting discs, a CD-Rrecorded on the system will be compatible with most CD-ROM drives found onPCs. Likewise, a DVD+R recorded on the system will be compatible with mostDVD drives.

To use a compatible DVD on a PC, the PC must have the ability to read the UDFfile format used by the system to write to DVDs. This may require adding thiscapability to your PC.

Installing a UDF ReaderThe system uses the UDF file format to write to DVDs. PCs running the Win-dows XP operating system can read this file format directly. If your PC uses anyother operating system, a UDF reader must be installed on the PC. UDF readersare available for downloading from the Internet. Follow the installation instruc-tions for the UDF reader that you choose.

Loading and Ejecting a Disc

NOTEThe recommended method of opening the DVD tray is to click Eject in thePatient Directory display. This method ensures that discs recorded on the systemare compatible with the greatest number of DVD and CD-ROM drives. In addi-tion to creating compatibility issues, using the eject button on the front of thedrive can also result in lost exam data if a disc is removed while an exam is inprogress.

➤ To load and eject a DVD or CD

1. To open the tray, click Eject in the Patient Directory.

2. Place a disc into the tray. Ensure that the disc is seated properly in the recessin the tray.

3. To close the tray, click Eject again or gently push the tray in until it closes.

6 Customizing Your SystemYou can customize your system in several ways to make it more useful for you.You can create presets designed specifically for the exams you perform, you canchange system settings to reflect your needs, and you can add options to enhanceyour imaging abilities.

PresetsA preset is a group of settings that optimizes the system for a specific type ofexam. Presets establish many initial settings, such as gain value, color map, filter,and items on the Annotation and Measurement touch screens.

When you turn on your system, the default preset is active. Before you begin anexam, be sure that the appropriate preset is active.

You can choose from several default presets. You cannot delete these default pre-sets. However, they provide a starting point from which you can create your ownpresets. You can create and store up to 45 presets per transducer/applicationcombination, depending on the number of buttons available on the individualTransducer touch screens. If you need to create more than 45 presets pertransducer, you can save presets to a DVD and restore them when you need touse them.

NOTEPresets are available only if you purchased the corresponding application-packageoption.

About Clinical Options and Tissue Specific Presets Clinical options are broad areas of medical study. Within each clinical option,there are Philips Tissue Specific presets for specific areas of study. For example,within the Small Parts clinical option, the Tissue Specific presets are Thyroid, Tes-ticle, Breast, and Superficial. The Transducer touch screen lists the available clin-ical option/Tissue Specific preset combinations for the selected transducer.

You specify how the system will be set up for operation by selecting a clinicaloption/Tissue Specific preset. The more specific you are about your intended useof the system, the more you can benefit from Tissue Specific Imaging.

About Quick Save PresetsQuick Save presets provide a quick way to set imaging parameters to the valuesyou prefer for a specific exam type. Using the Quick Save feature, you can definepresets for any combination of clinical option, preset, and transducer. A QuickSave preset stores the primary imaging mode and settings that are active whenyou create the Quick Save preset.

Once you create a Quick Save preset, it appears on the Transducer touchscreen when the associated transducer is selected. When you select the QuickSave preset, the system automatically invokes the settings in the preset. You canmodify or delete existing Quick Save presets, copy them onto a DVD, and loadthem into another iU22 system.

The number of Quick Save presets you can store for a transducer/applicationcombination is limited only by the number of buttons available on the corre-sponding Transducer touch screen. The number of buttons available, in turn, isdependent on which application is selected and how many Tissue Specific presetsthat application includes.

CW Doppler Continuous-wave (CW) Doppler uses continuously transmitted and receivedultrasound energy to generate a spectral display. Pulsed Doppler uses pulses ofsound waves to evaluate flow characteristics of direction and speed in a specificlocation. However, in pulsed Doppler, the time for echo information to return tothe transducer may be too great to accurately measure certain high velocities,resulting in false directional information known as aliasing.

As an alternative, CW Doppler allows accurate high-velocity determination.Though the sample rates for CW Doppler are greater than those available inpulsed Doppler, range information is unavailable. Accordingly, CW Doppler isappropriate when acquisition of high velocities is a more critical exam require-ment than capturing range information.

Only certain transducers provide CW capability. Pressing the CW control turnsCW Doppler on or off. CW is available only if the current transducer supportsCW operation.

3D Acquisition Two options are available for acquiring a 3D data set on your system: Freehand3D and 4D imaging. Both options include support for setup, acquisition of images,and viewing and manipulation of 3D volume and 2D multiplanar reformatted(MPR) views.

The Freehand 3D option allows you to acquire an uncalibrated series of 2Dframes in Cine memory for 3D volume rendering. Freehand 3D is allowed only inradiology applications on non-motorized transducers. After acquisition, the sys-tem renders a 3D volume image from the 2D frames. You can use all conventionaltransducers for Freehand 3D imaging.

The 4D imaging option requires a 3D transducer. This option provides sin-gle-sweep 3D (single 3D volume) acquisition and continuous acquisition of multi-ple 3D volumes (4D).

The Freehand and 4D imaging options both include support for setup, acquisitionof images, and viewing and manipulation of 3D volume and "MPR views" onpage 440.

Once the images are acquired, you can adjust thresholds and image enhancementsettings, rotate 2D multiplanar images, rotate volume images, trim extraneousimage information, magnify images, and view Cine sequences.

About Acoustic Artifacts in 3D ImagingResolution, attenuation, and propagation artifacts are all common to 3Dimaging. Careful scrutiny of the original 2D images is necessary to identify andpreclude these types of artifacts from the 3D volume image.

Gain, directional, and motion artifacts can present themselves in 3D imag-ing. Gain artifacts are mainly related to the use of excessive gain resulting in ran-dom color patterns in the 3D image that might be interpreted as diagnosticallysignificant. Directional artifacts are due to aliasing or directional confusion: Thevelocity range must be set properly, and the relationship between the transducerorientation and the flow vector must be understood. Patient motion can produceflash artifacts that are less obvious in 3D images than in 2D imaging.

Acquisition, rendering, and editing artifacts are specific to 3D volumeimages. Acquisition artifacts are related to patient motion, organ motion, or posi-tion-sensing errors. Rendering artifacts include elimination of structures by limit-

ing the region of interest boundaries, thresholding that eliminates structures, andadjacent structure artifacts that add additional information or hide structures.Editing artifacts result from data deleted from a rendered image.

Limb deficit artifacts are specific to 3D volume images. In some studies, par-tially absent fetal limb bones have been demonstrated. One explanation for themissing limbs was shadowing caused by adjacent skeletal structures. Overcomingthe limb deficit artifact can be accomplished by changing the transducer positionand the acquisition plane.

Pseudoclefting and pseudonarrowing artifacts may be related to limb defi-cit artifacts. Some studies have also shown that artifacts may be present in 3Dimaging of the fetal face. Being aware of pseudoclefting of the fetal face and psue-donarrowing of the fetal spine can help the sonographer understand and identifythese artifacts. As with 2D imaging it is important to verify putative physicaldefects using additional images and other modalities.

Drop-out and shadowing are present in 3D imaging although more difficult torecognize due to different and unfamiliar displays. Acoustic shadowing and otherartifacts look very different when displayed in 3D volumes and may be more diffi-cult to recognize than on standard 2D imaging. These artifacts may produceapparent defects such as limb abnormalities or facial clefts where they are notpresent. Acquiring data from multiple orientations may avoid artifacts of this type.

Color and Color Power Angio artifacts relating to gain may also be confusingin rendered images.

Motion artifacts in 3D volumes can be caused by fetal movement, cardiacmotion, as well as movement of adjacent structures.

About Freehand TechniqueIn Freehand 3D imaging, the system uses the 2D images acquired and stored inCine memory to create a 3D image. Because the quality of the multiplanar andvolume images is dependent upon the quality of the 2D acquisition, special atten-tion should be paid to 2D imaging technique. Observe the Freehand 3D progressindicator (Figure 7-3). Your scan should fill the progress indicator at least to theminimum frame indicator. Ideally, the progress bar should fill the entire indicatorat about the same time your sweep is complete.

It may take several tries for you to match the frame rate of the system with thesweep speed of the transducer. You may need to adjust the frame rate, line den-sity, and focal zones to change the frame rate.

In Freehand 3D imaging, using a standard transducer, you drag (slide) or pivot(tilt) the transducer at the region of interest to acquire the images. If you drag thetransducer, hold the transducer with the same angular relationship to the skinthroughout the motion to keep the image planes parallel to each other. If you tiltthe transducer, pivot the transducer at an even rate, keeping the face of the trans-ducer in the same position on the skin. Move the transducer at a constant rate forequally-spaced images.

About Freehand GeometryIn freehand 3D imaging, you can use one of two types of motion to acquire a 3Dvolume. Most often, you pivot a curved or sector transducer in a fan-like motionor drag a linear array transducer. If you select a curved or sector transducer, thesystem sets Geometry to Fan. If you select a linear array transducer, the systemsets Geometry to Linear. You can change the Geometry setting in the 3DStandby touch screen.

Optimizing 3D Image Quality There are several features that aid in adjusting 3D acquisition for optimal imagequality. 3D Opt on the touch screen lets you quickly select acquisition settingsoptimized for penetration (Pen), resolution (Res) or general use (Gen). SonoCTimaging is another important tool for improving image quality in freehand 3Dacquisition. You can also use XRes either during acquisition or during review.

The system generates a biopsy guideline through the displayed real-time ultra-sound image to indicate the anticipated path of the needle. You can use this guide-line to ensure that the needle or instrument is following the correct path.

When the biopsy display is active, a biopsy guideline is displayed on the left side ofthe screen during normal image presentation and on the right side when theimage presentation is reversed. Image presentation is defined by the location ofthe orientation marker.

When depth is changed, the biopsy display is redrawn to reflect the new relation-ships at the new depth setting.

Displaying the Biopsy Guideline The biopsy guideline can have a single, fixed path or multiple paths. The systemdetermines which guideline to display based on the type of biopsy guide availablefor the transducer you have selected.

➤ To turn the biopsy guideline on and off

1. Touch Next on the 2D touch screen, and then touch Biopsy. The biopsyguideline appears (Figure 8-1).

2. If you are using a biopsy guide with multiple needle paths, touch the control(for example, Angle A, Angle B) that corresponds to the path you will beusing.

3. To turn the biopsy guideline off, touch Biopsy again.

Panoramic Imaging has the ability to display an entire abnormality and show itsrelationship to adjacent structures on a single, static image.

Panoramic Imaging can be started from any live image format supported by thesystem, but it operates only in real-time 2D imaging. XRes image processing is notavailable in Panoramic standby or during acquisition. SonoCT Wide Screen imag-ing is not available in any stage of Panoramic Imaging. You can make measurementson the Panoramic image or on individual images in Cineloop review.

Panoramic Imaging is available with these transducers:

• C5-2

• C9-4

• C8-5

• L8-4

• L12-5

• L17-5

• 3D6-2

Panoramic Scanning Techniques

➤ To scan properly for Panoramic Imaging

1. Ensure that the system is imaging at a frame rate of at least 15 Hz.

2. Apply a sufficient amount of scanning gel (to prevent drag) to the entire areaof the body designated for Panoramic Imaging.

3. Perform a practice sweep to determine the desired scanning path.

4. Begin movement of the transducer smoothly and in a precise direction. If youfind that you are moving off plane or off of the desired path, you can stop for-ward motion and correct your orientation. Image registration stops if thetransducer is stationary. Continue movement at a slow and consistent speedalong the plane of interest.

Panoramic Imaging ArtifactsIn Panoramic Imaging, artifacts are most often caused by improper scanning tech-nique.

Page 197: Iu22 Reference Manual

iU22 User Reference453561170891 197

Imaging Features

Seams or tearing artifacts can be caused by moving the transducer too fast ortwisting the transducer during imaging. Twisting the transducer can also result inoverlapping frames in the Panoramic image.

Blurring artifacts are often related to the angle of the transducer to the skin.Tilting the transducer can result in blurring artifacts and loss of proper curvaturein the image. When using a linear transducer, always keep the full length of thetransducer face in contact with the body surface and perpendicular to the skinline. Panoramic Imaging on a highly curved body surface can also result in blurring.Another source of blurring is transducer pressure. Excessive or uneven pressureapplied to the transducer results in tissue deformation and can produce blurringartifacts.

Acquiring a Panoramic Data SetDuring acquisition all controls and menu selections are disabled except these:Freeze, the TGC slide controls, 2D, Output Power, and End Exam. You canuse 2D to adjust gain as you scan across structures of different densities.

➤ To acquire a Panoramic data set

1. Touch Panoramic. The system enters the standby stage, and the capturearea box appears.

2. Optimize the image as desired setting the depth, gain, focus, and other imageparameters.

3. Touch Start or press Update to begin Panoramic acquisition.

4. Move the transducer at a consistent speed in a direction that extends the fieldof view (width of the image). The composite image begins to form. When theCineloop buffer is full, acquisition automatically stops.

– To stop the acquisition manually before the buffer is full, touch Stop orpress Freeze. Touch Stop or press Freeze a second time to clear thePanoramic image and return to standby.

– If needed, touch Exit Panoramic to exit Panoramic Imaging and returnto 2D live imaging or select another imaging mode.

Performing Measurements on a Panoramic Image

WARNINGS• Do not use the skin line ruler for estimating depth on Panoramic images. Use

only the calibrated depth ruler for this purpose.

• Do not measure across Panoramic areas with no image data, such as the blackarea in a scan of the neck, leg, or other tightly curved anatomy.

On a Panoramic image, you can perform all 2D measurements except depth. Youcan delete measurements on a Panoramic image, but you cannot reactivate mea-surements.

You can make measurements on the Panoramic image or on individual images inCineloop review. If the object you are measuring is contained in an individualimage, make the measurements on the individual image instead of the Panoramicimage. This ensures that you will achieve optimal measurement accuracy.

Contrast Imaging 2D Contrast imaging is used in conjunction with ultrasound contrast agents toenhance imaging of blood flow and microcirculation. When you select Contrastimaging mode, the system is optimized according to the transducer, application,contrast agent, and imaging scenario you select.

SonoCT imaging is available when Contrast imaging is active.

Two General Imaging Contrast presets are available; one for normal MechanicalIndex (MI), which is based on microbubble destruction (Contrast ADI) and onefor low MI for real-time imaging of microbubbles (Contrast General). Contrastimaging is supported for these transducers:

• C5-2

• C8-4v

• L8-4

• C9-5ec

• S4-1

About Acoustic Artifacts in Contrast ImagingArtifacts can be generated during Contrast imaging by the interaction of the con-trast agent, the ultrasound beam, and the anatomy.

Rib artifact appears as a dark, linear area in a lateral part of a sector image. Ribartifact occurs when a rib blocks scan lines, preventing microbubbles in the rib’sshadow from resonating. You can minimize or eliminate rib artifacts by reposition-ing the transducer in relation to the ribs.

Page 204: Iu22 Reference Manual

Imaging Features

iU22 User Reference453561170891

204

Shadowing or attenuation is a common artifact that appears as a dark area,generally in the mid to far field. Shadowing is caused by administering the contrastagent at a high rate or concentration. The resulting high concentration ofmicrobubbles in an area causes backscatter of the ultrasound energy, preventingsufficient energy from reaching the area behind the concentration. Shadowing isalleviated as the contrast agent becomes diluted. You can avoid shadowing byadministering the contrast agent at a lower rate and concentration.

Swirling occurs when the higher level of ultrasound energy in the near field dis-rupts or destroys the microbubbles in the contrast agent. Factors that contributeto swirling are high MI, low blood flow near the apex, and low concentration ofcontrast agent. Frame rate can also have an effect on swirling.

Using Contrast Imaging

➤ To use Contrast imaging

1. Select a transducer with a Tissue Specific preset for Contrast imaging, andthen select that preset.

2. Begin imaging. Adjust Output Power and TGC gain only as needed.

Tissue Harmonic ImagingTissue Harmonic Imaging (THI) uses the harmonic frequencies generated by tis-sue. The fundamental transmit frequency results in a harmonic frequency echo.The harmonic frequency received from the tissue is a multiple of the fundamentaltransmit frequency. The fundamental and any accompanying artifacts are missingfrom the harmonic frequency that the system receives. The artifact reduction, andthe concomitant reduction in haze and clutter, increases contrast resolution andimproves border delineation. THI is useful in difficult-to-image patients.

Tissue Harmonic Imaging can be used in conjunction with SonoCT imaging andXRes image processing.

iSCAN Intelligent OptimizationiSCAN Intelligent Optimization is used to automatically optimize key imagingparameters during either 2D or Doppler acquisition. There are two options avail-able; 2D iSCAN Intelligent Optimization and Doppler iSCAN Intelligent Optimi-zation.

About 2D iSCAN Intelligent OptimizationPressing iSCAN during live 2D acquisition optimizes the system for imaging. Thesystem evaluates grayscale distribution to optimize TGC, compression (dynamicrange), and 2D gain for the image. The compression settings do not change;instead, the underlying dynamic range values used in each compression setting are

adjusted. The icon is displayed only when the selected transducer and TissueSpecific preset support iSCAN Intelligent Optimization. When you activateiSCAN, the icon changes to red for three seconds to indicate that the image hasbeen optimized.

When you press iSCAN, the current position of each TGC slide controlbecomes the zero position.

Touching Reset iSCAN restores the TGC and dynamic range settings in usebefore you activated iSCAN optimization. Touching Reset iSCAN also restores2D gain to the level set by the system when you selected the current transducerand application. iSCAN optimizes system settings based on the frame acquired atthe moment you press iSCAN. These settings remain unchanged until you pressiSCAN, touch Reset iSCAN, or change the affected controls manually.

If you are not satisfied with the brightness level set by iSCAN, you can change itby applying an offset value by using the rotary control below Set iSCAN on thesecond page of the 2D touch screen. This offset value will then be used to correctthe optimization process for the associated transducer each time you press

Measurements

Making a diagnosis based solely on measurements and calculations is not recom-mended. There are numerous factors to consider when using quantified data fromany ultrasound imaging system. A careful analysis of those factors indicates thatthe accuracy of each measurement and calculation is highly dependent on imagequality. Image quality in turn is highly dependent on system design, operator scan-ning technique, familiarity with system controls and, most important, patientechogenicity.

About Measurement AccuracyResolution is proportional to the transducer frequency. Penetration is inverselyproportional to the transducer frequency. Resolution is always best near the focalzone of the transducer where the ultrasound beam is narrowest. You set the focalpoint depth. Measurements are most accurate near the focal depth, and less accu-rate away from the focal point as the acoustic beam widens.

About Doppler Measurement AccuracyLower frequency transducers are capable of measuring higher velocity flows. Sam-ple volume size is limited laterally by the acoustic beam. Penetration is best withlow frequency transducers.

About Color and CPA Measurement AccuracyThe accuracy of a measurement made in Color imaging is subject to the same lim-itations as a similar type of measurement made on a gray-scale image. Do not useColor values for precise flow velocity quantification in any application. Color flowvalues are estimates of the mean velocity, and will not necessarily represent peakvelocities. The method of choice for quantifying flow for any application is spectralanalysis using pulsed or continuous-wave Doppler imaging.

About Display Size and Measurement AccuracyThe precision with which a caliper can be placed in an image can be improved bymaking sure that the area of interest fills as much of the screen as possible. In 2Dimaging, distance and area measurements are improved by minimizing the displaydepth and using the zoom function where possible. In M-mode and Doppler imag-ing, time measurements are improved by using the highest possible sweep speed.In Doppler imaging, velocity measurement accuracy is improved by using thesmallest possible vertical scale setting.

About Caliper Placement and Measurement AccuracyWhen making a measurement, accurate placement of the calipers is essential. Toimprove caliper placement precision:

• Use the video controls and the imaging controls to adjust the display for max-imum sharpness

• Use leading (closest to the transducer) edges or borders for start and stoppoints of the measurement

• Maintain a consistent transducer orientation for each type of measurement.

About Speed of SoundUltrasound imaging and Doppler algorithms assume that the speed of sound isconstant at 1,540 m/s, but the speed of sound varies for different tissue types. Incardiovascular applications, where soft tissues, blood, and fatty layers are allinvolved, the error is random but is typically on the order of 2% to 5%. Ensurethat your tissue-equivalent phantom meets the following specification: speed ofsound = 1,540 m/s. If your tissue-equivalent phantom does not meet this specifi-cation, linear measurements derived using your tissue-equivalent phantom will beinaccurate.

About Doppler AlignmentDoppler velocity measurements are most accurate when the acoustic beam isaligned parallel with blood flow. Deviations from the parallel alignment of up to 20degrees for Doppler angles result in measurement errors of 6% or less. For largeralignment errors (Doppler angles exceeding 20 degrees), the measurement accu-racy falls off rapidly, and use of angle correction is recommended (vascular appli-cations only). The Doppler angle correction appears in the patient report withthe Doppler measurements.

About AliasingPulsed-wave Doppler uses signal sampling techniques to compute a velocity spec-trum. A theoretical limit exists for the maximum measurable velocity. When mea-suring high velocities, the sampling rate, which is determined largely by the samplevolume depth, may be insufficient; and velocity wraparound (aliasing) may occur. Apossible result could be that normal, high-velocity, laminar flows would be per-

iU22 User Reference453561170891 225

Measurements

ceived as turbulence. Aliasing can be minimized, in some cases, by moving thebaseline, increasing the velocity scale, or using a lower frequency transducer. Incontinuous-wave Doppler, aliasing is virtually eliminated.

About Velocity Resolution in DopplerIn computing velocity spectra, the velocity field (the area where flow exists) isassumed to be stationary. In cardiovascular applications, velocity fields do notremain constant, owing to the pumping action of the heart. The dynamics ofblood flow places a practical upper limit on velocity resolution and spectral edgesharpness. The acoustic beam width determines the extent to which velocitiescan be differentiated in composite blood flow patterns.

About Acquisition and Algorithmic ErrorsIn general, there are two types of errors that can be introduced into a displayedmeasurement: acquisition and algorithmic.

Acquisition errors are introduced by ultrasound machine electronics, relating tothe front end signal acquisition, signal conversion, and the display of the image onthe screen. These machine errors are also introduced by generation of a pixelscale factor, application of that factor to the caliper positions on the screen, andthe subsequent measurement display. Calipers and readouts must be used againsta known phantom image displayed on the screen; it is impossible to state or test atolerance of a machine acquisition error by itself.

Algorithmic error is the error introduced by taking the basic measurements withacquisition errors as input to higher order calculations for display to the user. Thiserror is associated with floating point versus integer type math, and is also subjectto errors introduced by rounding versus truncating results for a given level of sig-nificant digit display of the values. The acquisition errors of the inputs are not car-ried forward into these higher calculations.

About FormulasSome formulas used in clinical applications are based on assumptions or approxi-mations, for example:

• Volume formulas may assume a specific three-dimensional shape.

• Pressure formulas use a simplified version of equations from fluid mechanics.

3D Volume MeasurementsVolume measurements are made using either the 3D Volume method or theStacked Contour method. The 3D Volume method uses an ellipsoid volumemeasurement tool. The result is the volume of the ellipse determined by the 2Dellipse and the orthogonal distance measurements combined.

The Stacked Contour method allows you to perform a volume measurementon an irregular shape in a 3D volume data set. Both methods of measuring 3Dvolume are available in the Caliper touch screen during 3D review. 3D volumemeasurements are valid only for volume data acquired using 3D transducers.Because volume data acquired using Freehand 3D is not calibrated, 3D measure-ment tools are unavailable for freehand acquisition.

About the Volume Flow MeasurementThe volume flow measurement has been used predominantly in the extremitiesfor vascular applications. General imaging applications have measured flow in theportal vein.

The volume flow measurement requires that you obtain a longitudinal view of thevasculature and measure its diameter. A Doppler waveform derived from thesame area is also required. The sample volume should be centered in and com-pletely insonate the vessel. The resulting Doppler waveform is then traced usingan automatic trace method that estimates the time-averaged mean, which is usedto calculate volume flow. The accuracy for this method of volume flow calculationis ±30%.

11 Calculations (Calc)Calc is a system control that provides access to the groups, measurements, andcalculations that make up a calculations package. Calculations packages are systemoptions that are associated with transducers and presets.

A calculations package contains one or more calc lists that organize groups, mea-surements, and calculations into a coherent tool for diagnostic analysis.

In the setups is an analysis configuration capability that allows you to create yourown calc lists including groups, measurements, and calculations. In addition, themeasurements and calculations can be associated with system and custom tablesand equations.

The groups, measurements, and the calculations derived by the system are basedon medical references. The User Reference, on the user information CD, containsa list of those references.

Calculations and PresetsWhen you select a transducer, you also select a preset. The preset you select hasat least one corresponding calculations package associated with it. The calcula-tions packages include a range of measurements and calculations for medical spe-cialties such as obstetrics, small parts, vascular, and gynecology. There is also ageneral calculations package that can be assigned to a measurement you mightwant to include in a patient report.

About the Calc DisplayWhen you press Calc, a calc list for the selected calculations package appearsacross the top of the display, and a measurement list appears along the left side ofthe display (Figure 11-1). The calc list consists of tabs. When you click on a tab inthe calc list, a corresponding measurement list appears along the left side of thedisplay.

The measurement list includes a list of measurement labels and space for themeasurement values. When you make measurements, you can enter the valuesfor the labels in the list. Conversely, you can select a label, then make a measure-ment, and the value will be entered into the list when you complete the measure-ment. You can enter and store up to five values for each label. Once you exceed

five values, the last value will be replaced by the newest value, a last-in, first-outscenario.

A group is several related measurements organized under one label. For example:+AFI is a group; when it is expanded, the related measurements are listed. In thecase of +AFI, clicking + expands the list, and values can be assigned to the differ-ent quadrants (LUQ, LLQ, RUQ, and RLQ) to calculate the amniotic fluidindex. Biophysical profile (BPP) is another example of a group. AFI/BPP is a tabin the Obstetrics calc list.

You can build and edit your own groups. Special, system-defined groups, known aslinked groups, contain default measurements and calculations that are consideredessential for specific imaging modes.

About Quick Save Presets and Calculations PackagesWith the Quick Save feature, you can define custom presets for any combinationof transducer and preset. A Quick Save preset stores all primary modes andmode settings that are active when the preset is created. When creating a QuickSave preset, you can specify the default calculations package, annotation, and bodymark. You can create as many Quick Save presets for a transducer as will fit onboth pages of the corresponding Transducer touch screen.

Once you have selected settings for various system parameters and saved themusing Quick Save, the system will automatically invoke these settings when youselect your Quick Save preset. You can also save Quick Save presets on removablemedia and load them into other systems.

About Calcs in ReviewIn general, measurements and calculations work the same way in Review as inimaging. One difference is that, in review, you cannot save or store measurementsmade on a recalled exam. Also, regardless of whether you are working in the cur-rent exam or a recalled exam, High Q Automatic Doppler is not available inReview.

Labeling MeasurementsThere are two ways to assign a measurement value to a measurement label. Theeasiest method is to make measurements directly. Selecting a measurement labelautomatically selects the appropriate measurement tool and starts the measure-ment. When the measurement is complete, the measurement value is automati-cally assigned to the selected measurement label.

The other method of assigning measurement values lets you make measurementsusing a tool selected from the Calipers touch screen and then assign the mea-

About Simpson’s Rule CalculationsSimpson’s Rule calculates the ejection fraction (EF) from the change in the leftventricular volume between diastole and systole. The left ventricular volumes arederived from traces of the endocardium obtained at end diastole and end systole.

In the System Settings setups, two methods are available for tracing a Simp-son's left ventricular volume: Manual and Adjustable Template. Select the oneof your choice.

The adjustable template automates the manual method by providing three anchorpoints from which you can make fine adjustments: the medial mitral annulus, thelateral mitral annulus, and the apex. Both methods allow the system to automati-cally trace and calculate the volume of 20 evenly-spaced discs from the apex tothe base of the left ventricle.

About GroupsA group is a label that includes more than one measurement and zero to manycalculations. For example, AFI is a group consisting of LUQ, LLQ, RUQ, and RLQmeasurements. Groups can be system-defined or user-defined. A linked group is aspecial, system-defined group that contains default measurements and calculationsthat are essential for specific imaging modes. The measurements and calculationsof other groups consist of labels only. When you select an linked group, the spe-cial measurements and calculations are highlighted. Linked groups cannot bedeleted.

About Custom Fetal MeasurementsYou can create your own fetal measurements for your local lab. This capabilityallows you to include measurements and calculations that may not be widelyaccepted or may be recently published and that therefore are not included in thesystem. You create custom measurements using Analysis Config in the setups.The corresponding fetal age, weight, growth tables, and equations can also be cre-ated.

Although you can associate a custom measurement with a fetal table, the ultra-sound age derived from the custom measurement is not included in the averageultrasound age (AUA) calculation.

About Custom Fetal Age and Growth TablesYou can define your own fetal age and growth tables for both the system defaultmeasurements and your own custom measurements.

You must supply the author name, the measurement the fetal age is based on,valid input range and standard deviation, output accuracy range, and output units(days or weeks and days).

The output units in which the growth tables are expressed is inferred from thetype of measurement (ratios do not have units, some have percentages, weight isin grams, etc.). For fetal growth graphs, you must also define the low and highranges as the 5th and 95th percentiles or plus or minus two standard deviations(SD).

Calculations (Calc)

You can create the table, view and edit the table, and delete the table from thesystem. You can also delete lines from the table, correct single values, insert linesinto the table inadvertently skipped during original definition.

About Custom Age, Weight, and Growth EquationsYou can define your own fetal age, weight, and growth equations. All of the sys-tem default measurements are available for use in your custom equations. Theequations can be complex polynomial equations typical of fetal age, weight, andgrowth relationships. Multiple input parameters, constants, and mathematicalfunctions are allowed.

You must enter all information required for proper system use and reporting,including the author name, measurement label, valid input range, output rangeaccuracy, output age units.

The data that you enter for the equations should be checked for possible entryerrors and inconsistencies.

About Prior Exams and Fetal Growth GraphsPrior exam measurements can be displayed along with current exam measure-ments to show trends in fetal growth. For a multiple gestation, tabs correspondingto up to five fetuses are available. Across from the exam date for each prior examthe BPD, HC, AC, FL, EFW, CI, and HC/AC measurements for up to five priorexams can be entered.

The prior exam data is entered in two ways: manually from the keyboard or auto-matically from system memory. Manually entered prior exam data is editable untilyou use End Exam, Pause Exam, or Cancel Exam. Prior exam data will beavailable only if the exam has not been deleted from the system hard drive. Auto-matically entered prior exam data cannot be edited.

About Fetal Growth GraphsFetal growth graphs are available in the OB calculations package. The graphs pro-vide the capability to assess fetal growth relative to a normal growth graph. Thegrowth graph for a specific measurement label is displayed with the positive andnegative standard deviations or relevant percentiles. The ultrasound age derivedfrom your measurements is then plotted on the graph relative to the growthgraph. Prior study data can also be plotted relative to the standard growth graph.

Depending on the graph, the vertical axis is marked off in centimeters for mea-surements, percent for ratios, or grams for fetal weight. The graph has age inweeks along the horizontal axis. The age reference used to plot points on thehorizontal axis is either the manually entered established due date or the agebased on the date of the last menstrual period (LMP) entered into the patientdata. If neither is available, then no points are plotted on the graph.

A multiple gestation evaluation provides one graph with up to five sets of data. Onthe graphs report, a symbol legend is available to identify the symbols used for thedifferent fetuses of the multiple gestation.

The default for the calculation from GA in Graphs will be LMP, unless only theestablished due date is defined in patient data entry. If LMP and the establisheddue date are unavailable, the graph will appear without GA symbols.

Prior exam dates will be listed on the graphs report. Up to five prior exam datescan be listed.

You can print the graphs by clicking Print Graphs.

14 TransducersThe transducer that you select is the most important factor in image quality. Opti-mal imaging cannot be attained without the correct transducer. The system isoptimized for use based on your transducer selection.

The system limits patient contact temperature to 41 degrees Celsius, and acous-tic output values to their respective U.S. Food and Drug Administration limits. Apower-protection circuit protects against over-current conditions. If the powermonitor protection circuit senses an over-current condition, then the drive cur-rent to the transducer is shut off immediately, preventing overheating of thetransducer surface and limiting acoustic output. Validation of the power protec-tion circuit is performed under normal system operation.

CAUTIONMechanical transducers, such as the 3D6-2, should be operated only at normaloperating temperatures (50°F to 104°F or 0°C to 40°C). Operating a mechanicaltransducer at lower temperatures can damage it.

Transducer SelectionPressing Transducer displays the Transducer touch screen. From this touchscreen, you select a transducer and a preset. (The preset can be a Tissue Specificpreset or a Quick Save preset.) After you select the clinical option/preset, the sys-tem calibrates the transducer, enables the transducer for operation, and updatessystem status to reflect the transducer type and the preset you selected.

Clinical Options and TransducersThe clinical options, or applications, for each transducer for the system are listedhere (Table 14-1).

Acoustic ArtifactsThe transducer adds its own signature to the echo information in the form ofbeam width effects, axial resolution limitations, and frequency characteristics. Thecontrol choices made by the sonographer that affect amplification, signal process-ing, and echo signal display can lead to significant differences in the displayedappearance of echo data. Following is a brief discussion of acoustic artifacts. Anunderstanding of the physical basis for the production of signals displayed onultrasound images is helpful in minimizing artifacts on images and interpreting theresults of studies.

An artifact is an echo displayed in a different position than its correspondingreflector in the body. Artifacts can also be caused by intervening tissue properties.Artifacts can originate from external noise, reverberations, multi-path reflections,or misadjusted equipment. They can also come from the ultrasonic beam geome-try and unusual changes in beam intensity. Artifacts and their manifestations arelisted below, and following are some definitions of various artifacts.

• Added objects displayed as speckle, section thickness, reverberation, mirrorimage, comet tail, or ring down

• Missing objects due to poor resolution

• Incorrect object brightness due to shadowing or enhancement

• Incorrect object location due to refraction, multi-path reflections, side lobes,grating lobes, speed error, or range ambiguity

• Incorrect object size due to poor resolution, refraction, or speed error

• Incorrect object shape due to poor resolution, refraction, or speed error

Acoustic saturation occurs when received signals reach a system’s high-ampli-tude limit. At that point the system becomes unable to distinguish or display signalintensities. At the point of saturation, increased input will not increase output.

Aliasing occurs when the detected Doppler frequency exceeds the Nyquistlimit. It is characterized on the spectral display by the Doppler peaks going off thedisplay, top or bottom, and then continuing on the other side of the baseline. Onthe Color display an immediate change in color from one Nyquist limit to theother is seen.

Comet tail is a form of reverberation artifact produced when two or morestrong reflectors are close together and have a high propagation speed. In thiscase, sound does not travel directly to a reflector and back to the transducer; anda strong linear echo appears at the reflector and extends deeper than the reflec-tor.

Enhancement is an increased relative amplitude of echoes caused by an inter-vening structure of low attenuation.

Focal enhancement, also known as focal banding, is the increased intensity inthe focal region that appears as a brightening of the echoes on the display.

Mirror imaging artifact is most commonly seen around the diaphragm; this arti-fact results from sound reflecting off another reflector and back.

Mirroring is the appearance of artifacts on a spectral display when there isimproper separation of forward and reverse signal processing channels. Conse-quently, strong signals from one channel mirror into the other.

Multi-path positioning and refraction artifacts describe the situation in whichthe paths to and from a reflector are different. The longer the sound takes travel-ing to or from a reflector, the greater the axial error in reflector positioning(increased range). Refraction and multi-path positioning errors are normally rela-tively small and contribute to general degradation of the image rather than togross errors in object location.

Propagation speed errors occur when the assumed value for propagationspeed by the ultrasound system is incorrect. If the actual speed is greater thanthat assumed, the calculated distance to a reflector is too small, and the reflectorwill be displayed too far from the transducer. Speed error can cause a structure tobe displayed with incorrect size and shape.

Range ambiguity can occur when reflections are received after the next pulseis transmitted. In ultrasound imaging, it is assumed that for each pulse produced,all reflections are received before the next pulse is sent out. The ultrasound sys-tem calculates the distance to a reflector from the echo arrival time assuming thatall echoes were generated by the last emitted pulse. The maximum depth to beimaged unambiguously by the system determines its maximum pulse repetitionfrequency.

Reverberation is the continuing reception of a particular signal because ofreverberation rather than reflection from a particular acoustic interface. This phe-

iU22 User Reference453561170891 321

Transducers

nomenon is analogous to the effect created by mirrors positioned on oppositewalls when an object, a head for instance, is placed between the mirrors. Theimage of the head is reflected back and forth infinitely between the two mirrors,creating the optical illusion of multiple heads. Reverberations are easily identifi-able, because they are equally spaced on the display screen.

Scattering is the diffuse, low-amplitude sound waves that occur when acousticenergy reflects off tissue interfaces smaller than a wavelength. In diagnostic ultra-sound, Doppler signals come primarily from acoustic energy back-scattered fromred blood cells.

Shadowing is the reduction in echo amplitude from reflectors that lie behind astrongly reflecting or attenuating structure. This phenomenon occurs when scan-ning a lesion or structure with an attenuation rate higher than that of the sur-rounding tissue. The lesion causes a decrease in beam intensity, which results indecreased echo signals from the structures beyond the lesion. Consequently, adark cloud behind the lesion image forms on the screen. This cloud, or shadow, isuseful as a diagnostic clue.

Side lobes (from single-element transducers) and grating lobes (from arraytransducers) cause objects that are not directly in front of the transducer to bedisplayed incorrectly in lateral position.

Speckle appears as tissue texture close to the transducer but does not corre-spond to scatterers in tissue. It is produced by ultrasound wave interference andresults in general image degradation.

Spectral broadening is a display phenomenon that occurs when the number ofenergy-bearing Fourier frequency components increases at any given point intime. As a consequence, the spectral display is broadened. Spectral broadeningcan indicate the disturbed flow caused by a lesion, and therefore it is importantdiagnostically. However, broadening can also result from interaction between flowand sample volume size, in which case it is an artifact.

Speed of sound artifacts occur if the sound propagation path to a reflector ispartially through bone, and the speed of sound is greater than in the average softtissue. Echo position registration artifacts will be produced. Reflectors appearcloser to the transducer than their actual distance because of this greater speedof sound, resulting in a shorter echo transit time than for paths not containingbone.

Transducer CoversTransducer covers are recommended for clinical applications of an invasivenature, including intraoperative, transrectal, intravaginal, transesophageal, andbiopsy procedures. Philips Ultrasound recommends the use of qualified covers.See "Ordering Supplies and Accessories" on page 31 to order qualified covers.

For procedures on using transducer covers, refer to the instructions providedwith the covers.

WARNINGS• Some transducer covers contain natural rubber latex and talc, which can

cause allergic reactions in some individuals. Refer to the FDA Medical Alert,March 29, 1991, reprinted here.

• In neurosurgical applications, sterilized transducers should be used with ster-ile gel and a sterile pyrogen-free transducer cover.

• If the sterile transducer cover becomes compromised during an intraopera-tive application involving a patient with Creutzfeldt-Jakob disease, follow therecommendations described in “Transmissible Spongiform Encephalopathy” inthe Getting Started manual.

• Transducer covers are disposable and must not be reused.

• If an installed transducer cover is cut or contaminated prior to use, the probeshould be cleaned and disinfected, and a new sterile cover installed.

FDA Medical Alert, March 29, 1991, Allergic Reactions to Latex-Containing Medical Devices

Because of reports of severe allergic reactions to medical devices containing latex(natural rubber), the FDA is advising health care professionals to identify theirlatex sensitive patients and be prepared to treat allergic reactions promptly.Patient reactions to latex have ranged from contact urticaria to systemic anaphy-laxis. Latex is a component of many medical devices, including surgical and exami-nation gloves, catheters, intubation tubes, anesthesia masks, and dental dams.

Reports to the FDA of allergic reactions to latex-containing medical devices haveincreased lately. One brand of latex cuffed enema tips was recently recalled afterseveral patients died as a result of anaphylactoid reactions during barium enema

Transducers

procedures. More reports of latex sensitivity have also been found in the medicalliterature. Repeated exposure to latex both in medical devices and in other con-sumer products may be part of the reason that the prevalence of latex sensitivityappears to be increasing. For example, it has been reported that 6% to 7% of sur-gical personnel and 18% to 40% of spina bifida patients are latex sensitive.

Proteins in the latex itself appear to be the primary source of the allergic reac-tions. Although it is not now known how much protein is likely to cause severereactions, the FDA is working with manufacturers of latex-containing medicaldevices to make protein levels in their products as low as possible.

FDA’s recommendations to health professionals in regard to this problem are asfollows:

• When taking general histories of patients, include questions about latex sensi-tivity. For surgical and radiology patients, spina bifida patients and health careworkers, this recommendation is especially important. Questions about itch-ing, rash or wheezing after wearing latex gloves or inflating a toy balloon maybe useful. Patients with positive histories should have their charts flagged.

• If latex sensitivity is suspected, consider using devices made with alternativematerials, such as plastic. For example, a health professional could wear anon-latex glove over the latex glove if the patient is sensitive. If both thehealth professional and the patient are sensitive, a latex middle glove could beused. (Latex gloves labeled “Hypoallergenic” may not always prevent adversereactions.)

• Whenever latex-containing medical devices are used, especially when thelatex comes in contact with mucous membranes, be alert to the possibility ofan allergic reaction.

• If an allergic reaction does occur and latex is suspected, advise the patient of apossible latex sensitivity and consider an immunologic evaluation.

• Advise the patient to tell health professionals and emergency personnel aboutany known latex sensitivity before undergoing medical procedures. Consideradvising patients with severe latex sensitivity to wear a medical identificationbracelet.

The FDA is asking health professionals to report incidents of adverse reactions tolatex or other materials used in medical devices. (See the October 1990 FDADrug Bulletin.) To report an incident, call the FDA Problem Reporting Program,

Starter kits, which include the biopsy guide or biopsy guide bracket and proce-dure kits, are available from CIVCO Medical Instruments; see "Ordering Suppliesand Accessories" on page 31.

Attaching and Removing a Biopsy GuideDetailed information about attachment and removal of biopsy guides is providedwith the biopsy starter kits, guides, and brackets.

WARNINGS• Inspect all components and the transducer. Ensure that the biopsy guide you

are using is the correct one for the transducer, the system, and system soft-ware. Your Philips Ultrasound customer service representative can verify thisinformation for you.

• Use only Philips-approved biopsy guides, brackets, supplies, components, andaccessories. Other brands may not properly fit Philips Ultrasound transduc-ers. Improper installation may result in patient discomfort.

• Some biopsy guides must be installed over a sterile transducer cover. Refer tothe instructions provided with the biopsy guide.

• After each use, biopsy guides must be either sterilized or disposed of,depending upon the type. Refer to the instructions included with the biopsyguide.

• Most transducers can only be disinfected; they cannot be sterilized. Only thetransducer cover provides the sterile barrier.

Using the Biopsy Guideline Display

WARNINGDo not attempt to use the biopsy guide until you have read the instructions forselecting the display, installing the sterile transducer cover, and verifying alignmentof the biopsy guide.

The system generates a biopsy guideline through the displayed real-time ultra-sound image to indicate the anticipated path of the needle. You can use this guide-line to ensure that the needle or instrument is following the correct path.

When the biopsy display is active, a biopsy guideline is displayed on the left side ofthe screen during normal image presentation and on the right side when theimage presentation is reversed. Image presentation is defined by the location ofthe orientation marker.

When depth is changed, the biopsy display is redrawn to reflect the new relation-ships at the new depth setting.

➤ To show or hide the biopsy guideline

1. Touch Next on the 2D touch screen, and then touch Biopsy. The biopsyguideline is displayed (Figure 15-1).

2. If you are using a biopsy guide with multiple needle paths, touch the control(for example, Angle A, Angle B, and so on) that corresponds to the pathyou will be using.

3. To hide the biopsy guide, touch Biopsy again.

➤ To move the biopsy depth cursor

Rotate the trackball to move the depth cursor along the guideline. The BiopsyDepth measurement value changes to reflect the distance between the biopsyguide reference point origin and the depth cursor.

WARNINGS• Disinfectants listed in “Disinfectants Compatibility” are recommended

because of their chemical compatibility with product materials, not their biolog-ical effectiveness. For the biological effectiveness of a disinfectant, refer to theguidelines and recommendations of the disinfectant manufacturer, Associationfor Practitioners in Infection Control, U.S. Food and Drug Administration, andU.S. Centers for Disease Control.

• The level of disinfection required for a device is dictated by the type of tissueit will contact during use. Ensure the disinfectant type is appropriate for thetype of transducer and the transducer application. For information, see thedisinfectant label instructions and the recommendations of the Association forPractitioners in Infection Control, U.S. Food and Drug Administration, andU.S. Centers for Disease Control.

• The use of sterile transducer covers and sterile coupling gel is recommendedfor clinical applications where introduction into a sterile site is possible. Donot apply the transducer cover and gel until you are ready to perform the pro-cedure. Repeated long-term exposure to coupling gel can damage transduc-ers.

• Use of a transducer cover is recommended but not required on transesoph-ageal and intracavity exams.

• In neurosurgical applications, sterilized transducers should be used with ster-ile gel and a sterile pyrogen-free transducer cover.

• Transducer covers can contain natural rubber latex, which may cause allergicreactions in some individuals. Refer to the following FDA Medical Alert onLatex Products.

Latex

FDA Medical Alert, March 29, 1991, Allergic Reactions to Latex-Containing Medical Devices

Because of reports of severe allergic reactions to medical devices containing latex(natural rubber), the FDA is advising health care professionals to identify theirlatex sensitive patients and be prepared to treat allergic reactions promptly.Patient reactions to latex have ranged from contact urticaria to systemic anaphy-

Page 337: Iu22 Reference Manual

Disinfectants and Gels

laxis. Latex is a component of many medical devices, including surgical and exami-nation gloves, catheters, intubation tubes, anesthesia masks, and dental dams.

Reports to the FDA of allergic reactions to latex-containing medical devices haveincreased lately. One brand of latex cuffed enema tips was recently recalled afterseveral patients died as a result of anaphylactoid reactions during barium enemaprocedures. More reports of latex sensitivity have also been found in the medicalliterature. Repeated exposure to latex both in medical devices and in other con-sumer products may be part of the reason that the prevalence of latex sensitivityappears to be increasing. For example, it has been reported that 6% to 7% of sur-gical personnel and 18% to 40% of spina bifida patients are latex sensitive.

Proteins in the latex itself appear to be the primary source of the allergic reac-tions. Although it is not now known how much protein is likely to cause severereactions, the FDA is working with manufacturers of latex-containing medicaldevices to make protein levels in their products as low as possible.

FDA’s recommendations to health professionals in regard to this problem are asfollows:

• When taking general histories of patients, include questions about latex sensi-tivity. For surgical and radiology patients, spina bifida patients and health careworkers, this recommendation is especially important. Questions about itch-ing, rash or wheezing after wearing latex gloves or inflating a toy balloon maybe useful. Patients with positive histories should have their charts flagged.

• If latex sensitivity is suspected, consider using devices made with alternativematerials, such as plastic. For example, a health professional could wear anon-latex glove over the latex glove if the patient is sensitive. If both thehealth professional and the patient are sensitive, a latex middle glove could beused. (Latex gloves labeled “Hypoallergenic” may not always prevent adversereactions.)

• Whenever latex-containing medical devices are used, especially when thelatex comes in contact with mucous membranes, be alert to the possibility ofan allergic reaction.

• If an allergic reaction does occur and latex is suspected, advise the patient of apossible latex sensitivity and consider an immunologic evaluation.

• Advise the patient to tell health professionals and emergency personnel aboutany known latex sensitivity before undergoing medical procedures. Consider

advising patients with severe latex sensitivity to wear a medical identificationbracelet.

The FDA is asking health professionals to report incidents of adverse reactions tolatex or other materials used in medical devices. (See the October 1990 FDADrug Bulletin.) To report an incident, call the FDA Problem Reporting Program,operated through the U.S. Pharmacopeia toll-free number: 800-638-6725. (InMaryland, call collect 301-881-0256.)

WARNINGThe level of disinfection required for a device is dictated by the type of tissue itwill contact during use. Ensure the disinfectant type is appropriate for the type oftransducer and the transducer application. For more information, see the disinfec-tant label instructions and the recommendations of the Association for Practitio-ners in Infection Control, U.S. Food and Drug Administration, and U.S. Centersfor Disease Control.

CAUTIONIf you use an isopropyl alcohol solution for disinfection, ensure the solution is only70% alcohol or less. Solutions of more than 70% alcohol can cause product dam-age.

Some disinfectants are recommended because of both their biological effective-ness (as qualified through the FDA 510(k) process) and their chemical compatibil-ity with Philips Ultrasound product materials. Other disinfectants arerecommended because of compatibility with Philips Ultrasound product materialsonly and not biological effectiveness.

Refer to "Choosing a Disinfectant" on page 350 and "Factors Affecting Disinfec-tant Efficiency" on page 351 for standard industry recommendations on disinfec-tion and information that can help you choose an appropriate disinfectant for therequired level of disinfection.

Choosing a DisinfectantTo choose an appropriate disinfectant, you first must determine the required levelof disinfection, based on the device classification (Table 16-1).

Use the following two Web sites to view lists of common active ingredients rec-ommended to achieve each level of disinfection:

• http://www.fda.gov/cdrh/ode/germlab.html

• http://www.cdc.gov/ncidod/hip/Sterile/sterile.htm

Also, low- and intermediate-level disinfectants marketed for use on medicalinstruments and based on quaternary ammonium compounds (QUATS) orsodium hypochlorite (NaOCl), equal to or less than 0.6%, are approved for use. In

Table 16-1 Levels of Disinfection Requirements

Classification Definition Level of Disinfection

Critical Device enters otherwise sterile tissue (intraoperative applications)

Sterilization

Semi-critical Device contacts mucous membranes (intracavity applications)

High (tuberculocidal)

Noncritical Device contacts intact skin Intermediate or low

Disinfectants and Gels

addition, 70% isopropyl alcohol (IPA) and household bleach at a concentration of10% or less is also acceptable for use. All products must be used in a spray orwipe application.

Factors Affecting Disinfectant EfficiencyThe following factors will affect the efficiency of a disinfectant solution:

• Duration of exposure

• Concentration and potency of the disinfectant

• Quantity and location of the contamination

• Resistance of the contaminate

• Organic matter on the item to be disinfected

Disinfectants ManufacturersFor contact information on disinfectants and gels manufacturers, call Philips Ultra-sound Customer Service at 800-433-3246 (North America) or your local PhilipsUltrasound representative (outside North America).

Disinfectants Compatibility TableTable 16-2 lists the disinfectants compatible with the transducer available for yoursystem. If you need additional assistance, call Philips Ultrasound Customer Ser-vice at 800-433-3246 (North America) or your local Philips Ultrasound represen-tative (outside North America).

Managing Data SecurityThe Health Insurance Portability and Accountability Act (HIPAA) was passed bythe U.S. Congress on August 2, 1996, and became effective April 2003. The pri-mary purpose of HIPAA is to provide improved portability of health benefits andbetter accountability in the area of health-care fraud. To help hospitals complywith HIPAA, this system protects the health-care information of individualsagainst access without consent or authorization.

The ultrasound system can be configured to protect patient data by requiringusers to log on by entering a personal password. Protected data is defined as previ-ously stored patient data and images. Users can access protected data whilelogged onto the system. Access to patient data is denied after the user logs off ofthe system, cycles system power, or does not use the system during the time-outperiod set by the system administrator. The current patient’s data is not pass-word-protected until images for the current patient are stored to the network.

The system automatically records all transactions related to patient data in a logfile on the system hard drive. It is the responsibility of the system administrator toarchive and clear the log file at regular intervals.

The Philips Custom percentile setting is a modification to the Hadlock, Harrist,and Martinez-Poyer equation for estimated fetal weight percentile. The PhilipsCustom percentile setting incorporates a broadening factor of 1.64 into the calcu-lation of the Z-score percentile. The broadening factor approximates the 10th to90th percentile.

Ln (weight) (g) = 0.578 + 0.332(MA) - 0.00354(MA2), 1 SD = 12.7 %

The Z-score is determined by using 0.127 * weight * 1.64.

The menstrual age (MA) range is 10 to 40 weeks.
