Definitions for "GAMMA KNIFE"
An advanced form of stereotactic or focused radiosurgery for benign processes and metastatic brain tumors that were previously considered inoperable or very high risk for conventional brain surgery. The "knife" is formed by 201 intersecting beams of gamma radiation that deliver a concentrated dose to a precise area of the brain.
The Gamma Knife uses older radiation technology that is confined to treating tumors in the head. The Gamma Knife uses ionizing radiation (gamma rays) produced by 201 cobalt-60 sources to target the tumor or abnormality.
A type of radiation therapy which uses high doses of gamma radiation aimed at tumors instead of a scalpel. Often used in the treatment of brain tumors.
