Gamma Knife Radiosurgery, or Stereotactic Surgery is a highly precise & sophisticated radiation therapy technique to focus about 200 tiny beams of radiation to well-defined, small targets in the brain. It is very effecting for the treatment of neurological conditions such as trigeminal neuralgia, atriovenous malformations and epilepsy.

The patient is made to lie down on a table that enters a machine which will deliver radiations. A helmet like head frame with holes in it is attached to the head. These holes deliver the radiations. The position of the head is adjusted accordingly to expose the exact location to radiations. Doctors & technicians carry this process from another room through the cameras & microphones.
