You will be pleased to know that the Gamma Knife is not really a surgical knife at all, but a knife composed of many individual radiation rays. These gamma rays are precisely focused on a specific target inside the head to effectively destroy the problem area without affecting normal brain tissue.

The Gamma Knife represents truly advanced non-invasive technology. Highly sophisticated computer software allows it to pinpoint intracranial lesions and tumors with exquisite precision. Using three-dimensional computerized dose planning, the 201 hemispherically arrayed sources of cobalt emit gamma rays that precisely converge on the target, creating a powerful peak of radiation with rapid fall-off to a minimal dose in the surrounding brain. Patients are usually able to be released from the hospital within 24 hours of their treatment and resume normal activities within a few days.
