 Gamma Knife
The gamma knife loses its ability to spare surrounding normal tissues as the number of targets increases, is not suitable for large targets (larger than three to four centimeters in size) and is not used for targets outside of the head.
The gamma knife works by a process called stereotactic radiosurgery, which uses multiple beams of radiation converging in three dimensions to focus precisely on a small volume, such as a tumor, permitting intense doses of radiation to be delivered to that volume safely.
Using the three-dimensional coordinates determined in the planning process, the frame is then precisely attached to the gamma knife unit to guarantee that when the unit is activated, the target is placed exactly in the center of approximately 200 precision-aimed, converging beams of (Cobalt-60 generated) gamma radiation.
