Objectives•Describe the trend of Stereotactic
Radiosurgery.•Describe/evaluate hardware/software
utilized.•Describe/evaluate information systems used.•Assess role of the nurse informaticist.•Examine legal and ethical issues involved.•Discuss advantages/disadvantages from
nursing perspective.

Stereotactic Radiosurgery:•Treats brain disorders with a single, high
dose of radiation.•Works the same as other radiation therapies.•Doesn't remove tumor, but distorts it's DNA.•Causes tumors to lose ability to reproduce.
(International Radiosurgery Association, 2010)

Hardware•MRI•Linear Accelerator•Collimator•Patient Docking Device•Target Verification Device

LINAC• Short for Linear
Accelerator.• Produces radiation needed
in SRT procedures.• Operated by a Radiation
Therapist.• Dosage calculated by a
Radiation Oncologist.• Beam exits through the
rotating Gantry.• Beams are shaped by the
Collimator. (Montagno & Sabbatini, 1997)

Software•Three dimensional software for treatment
planning.
•Dose delivery software.

Varian OncoView Picture Archiving and Communication System (PACS)
•Collects, stores and distributes diagnostic images.
•Digitalizes CT, MRI and X-ray results.•Enables ease of image sharing.•Enables collaborative approach to treatment.•Reduces data filing and retrieval times.•Saves time and money. •Reduces liability caused by errors and loss.
(Varian Medical Systems, 2010)

Varian OncoView PACS System Review•Radiology Information System•Used by all members of team.• Enables digitalization of image results.•Generally part of Local Area Network.•HL7 and ANSI Data Standards.•Necessary for use of SRS.

Advantages of SRS• Simpler Process• Shorter surgery times• Shorter patient recovery times• Less invasive • Fewer side effects vs. brain surgery.• Ability to reach deeper brain tissue.

Disadvantages of SRS•High cost of purchase and use•Risk of neurological injury•Risk of mechanical inaccuracy•Potential necessity of multiple visits

In Summary:•Often outpatient procedure for brain
surgery•High dose radiation distorts tumor DNA•Improved outcomes for many conditions•Reduced surgery and recovery time •Multidisciplinary team involved in
planning, implementation.
