Operational Radiation Safety

Example of a treatment plan with a gamma knife. (A) Dynamic shaping technique to protect critical structure (brain stem in this example). (B) Composite shots to shape dose distribution. Gamma stereotactic radiosurgery is an emerging technique with its own set of regulatory criteria. See article by Michael Sheetz on page S11 for more information.
