Stereotactic radiosurgery

Stereotactic Radiosurgery

By Angela Powers, RN


  • 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 radiosurgery1
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)


(Mongia, 2009)


  • MRI

  • Linear Accelerator

  • Collimator

  • Patient Docking Device

  • Target Verification Device


  • 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)


  • Three dimensional software for treatment planning.

  • Dose delivery software.

(Jefferson Radiation Oncology, 2010)


  • Ease of Use

  • Ease of Learning

  • Satisfaction with Using

  • Efficiency of Use

  • Error Tolerance

  • Fit of System to the Task

Varian oncoview picture archiving and communication system pacs
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
Varian OncoView PACS System Review (PACS)

  • 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
Advantages of SRS (PACS)

  • 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
Disadvantages of SRS (PACS)

  • High cost of purchase and use

  • Risk of neurological injury

  • Risk of mechanical inaccuracy

  • Potential necessity of multiple visits

Ethical legal issues
Ethical/Legal Issues (PACS)

  • Not available to everyone

  • Malpractice suits

Required informatics competencies and role of nurse informaticist
Required Informatics (PACS)Competencies and Role of Nurse Informaticist

  • Technical competencies - Modifier level

  • Utility competencies - Modifier level

  • Leadership competencies - User level

Functions and responsibilities of informatics nurses in srs
Functions and Responsibilities of Informatics Nurses in SRS (PACS)

  • Technical capacities

  • Utility capacities

  • Leadership capacities

(Kaminski, 2009)

In summary
In Summary: (PACS)

  • 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.
