4.2 ALIGNMENT OF X-RAY BEAM

1. Check with a level the vertical/horizontal position of the Column. Ifnecessary, modify the position of the Column with the screws attachedto the Base of the Column, a correct installation starts with a goodleveling of the column.

2. Check the level of the Tube-Collimator Assembly. The mechanicalinstallation provides a levelled Assembly, anyway check parallelism. Ifnecessary reinstall the Tube-Collimator Assembly. (Refer to installationsection).

3. Check the Receptor, first in horizontal position (thorax), then in verticalposition (Undertable). If necessary, move up or down the Receptorassembly with the Receptor Assembly leveling screws.

4. Place the Pivoting Arm in vertical position. The Tube-CollimatorAssembly has to beperfectly alignedwith theReceptor Assembly. Checkwith a level correct horizontal position of both assemblies.

5. Turn on Collimator light and center the Collimator in relation to theReceptor Table-Top. Horizontal and transversal position of the light axesprojected by the Collimator Lamp must be in line with the axes or filmsizes marked on the Table-Top.

If needed, modify Collimator position by carefully unscrewing andscrewing the four Centering Adjustment and Safety Screws (Allen) ofCollimator.

10. Load Cassette film Tray with cassette film 24x30 and insert it.

11. Make an exposure at 60 kVp / 5 mAs.

12. Process film and:

a. Check that the X-ray Field falls just within the image of the innerrectangle of the Collimator Test Tool.

If an edge of the X-ray Field falls out of the inner rectangle meansa misalignment of the Light Field respect to the X-ray Field. Themaximummisalignment allowed is 2% of SID (for SID 1.4m = 2.8cm tolerance).

Refer to Section 4.2.1 for alignment of Light Field with X-ray Field.


Service Manual

SM-0521R3 21

b. Check that the X-ray Beam is perpendicular to the plane of theImageReceptor. If the Image receptor is parallel to theTable-Top,the perpendicularity of the X-ray Beam can be checked using theBeam Alignment Test Tool with the Collimator Test Tool.

Based on next illustration, the criteria for SID at 1.4 meter is:

-- If the image of the two balls overlap (A) the X-ray Beam isperpendicular to within 0.5o.

-- If the image of the top ball (larger shadow) intercepts the firstcircle (B), the X-ray Beam is about 1.5o away from theperpendicular.

-- If the imageof the top ball (larger shadow) intercepts the secondcircle (C), the X-ray Beam is about 3o away from theperpendicular.In cases (A) and (B) perpendicularity is within tolerance for SID at1 meter (top ball is within or intercepting the first circle). The thirdcase (C) needs readjustment.

Refer to Section 4.2.2 for perpendicularity adjustment.

A B C

c. Check that the X-ray Beam is properly centered with the ImageReceptor. To determine the center of the Image Receptor, drawdiagonal lines from corner to corner of the X-ray Film. (Alternately,the film can be folded in half and creased at the center). The twolines will cross in the center of the Image Receptor (film). Thendraw diagonal lines from the corners of the imaged X-ray Field.

If the center of the X-ray Field and Image Receptor is the same,the diagonals of both sets of lines should cross at the same point.The maximum misalignment allowed is 2 % of SID (for SID 1.4m= 2.8 cm tolerance).

Refer to Section 4.2.3 for centering of X-ray Field and ImageReceptor.

6. Do not remove the Collimator Test Tool from its original position andadjust the Light Field bymoving theCollimator Unit and/or theCollimatorLamp.

a. Collimator Lamp must be ON during Light Field adjustment.

b. Modify Collimator position by carefully unscrewing and screwingthe four Centering Adjustment and Safety Screws (Allen) until theLight Field coincides with the axes reference imaged (numbersand dots) on the processed film.

c. If adjustment is still necessary, modify position of Collimator Lamp(refer to Collimator Manual).

7. Repeat exposure and procedure until the result is satisfactory. Themaximum misalignment allowed is 2 % of SID (for SID 1.4m = 2.8 cm oftolerance).

4.2.2 PERPENDICULARITY ADJUSTMENT OF X-RAY BEAM WITH IMAGE RECEPTOR

In case that perpendicularity is out of tolerance (top ball is out of first circle),adjust perpendicularity as follows:


The Receptor Assembly is factory adjusted (slightly up) and it isrecommended do not perform any additional correction. Duringprocedure, it must behorizontally placedat 0o (check positionwith a leveland with its indicator plate).


3. Turn on Collimator light and center the Collimator Test Tool with the lightaxes projected by the Collimator Lamp.

4. Place centered the Beam Alignment Test Tool (RMI model 162A) on theCollimator Test Tool and observe if shadow of the Beam Alignment TestTool is projected in equal proportion around it.

5. Check on the processed film the adjustment required to center the topball mark. Shadow around the Beam Alignment Test Tool can also helpto make a first correction.

6. Loosen slightly the four Safety Screws (Allen M8) of the Tube-CollimatorAssembly. If required, perform the following adjustments:

G For horizontal correction move horizontally the Tube-CollimatorAssembly before tightening the four Safety Screws.

G For vertical correction loosen or tighten carefully the four LevelingScrews (Allen M6) of the Tube-Collimator Assembly beforetightening the four Safety Screws.

7. Repeat exposure and procedure until the result is satisfactory (top ballmust be inside of the first circle).

DEVIATION

If the deviation is greater than 2% of SID, perform the following procedure:

1. Check on the processed film the correction required for centering theX-ray Field with the Image Receptor. Adjustments will be performed asthe samewaydescribed for Perpendicularity correction, soonly re-adjustit if really is necessary.

Centering adjustments may affect to perpendicularitycorrections.

2. Repeat exposure and check centering until the result is satisfactory(centers position are within tolerance).

4.3 FIELD SIZE INDICATOR TEST

Before starting with the Field Size Indicator Test, the Alignment ofX-Ray Beam Test, the Alignment of Light Field with X-Ray FieldTest and the SID Indicator Test should be performed.


2. Open the Collimator blades to set a Field Size of 24 x 30 cm for SID1,4 m.

3. Turn on the Collimator Light and center the Collimator in relation to theReceptor Table-Top. Horizontal and transversal position of the light axesprojected by the Collimator Lamp must be in line with the axes or FilmSize marked on the Table-Top.

4. Load on the Cassette Film Tray with a Cassette Film of 35 x 43 cmcentered and insert it.

5. Make an exposure at 60kVp, 1mAs.

6. Process film and check the following measurements known (refer toIllustration 4-7):

a. Measure the length of the X-ray Field on the Processed Film(identified as L)

b. Measure the width of the X-ray Field on the Processed Film(Identified as W)

7. With the measurements obtained and according to the field sizeindication selected, the results should be:

G Length dimension (L) = 300 mm

G Width dimension (W) = 240 mm

8. The difference between the indicated Field Size and the obtained FieldSize may not exceed 1.5 % (rejection limit) of the SID in either direction.Therefore the deviation in any direction should not be higher than 21 mm(rejection limit) for SID at 1.4 meter.

9. If the deviation of Field Size Indication is out acceptance limits, it isnecessary to readjust the index of Collimator Blades Control Knobs. Forthat, loosen each Collimator Control Knob and position it according todeviation. Repeat the complete tests until the X-Ray Field Size selected(24 x 30 cm) is obtained.
