Gamma knife

Gamma knife
A type of radiosurgery (radiation therapy) machine that acts by focusing low-dosage gamma radiation from many sources on a precise target. Areas adjacent to the target receive only slight doses of radiation, while the target gets the full intensity. The gamma knife is used to treat brain tumors, vascular malformations of the brain and temporal lobe epilepsy.
