Gamma Knife is the most accurate tool for treating brain tumors and other neurological disease without open brain surgery. This minimally invasive alternative to conventional brain surgery allows for a safe and effective treatment, typically with fewer side effects. As a result, this is an outpatient treatment.

Gamma Knife is a machine that uses imaging technology to focus hundreds of tiny radiation beams at a precise targeted location of the brain. Specialized equipment keeps your head steady during the procedure so radiation targets only your cancer, not healthy tissue. The procedure delivers a very strong dose of radiation so you generally need just one pain-free session. Since Gamma Knife spares most healthy tissue, you experience fewer side effects from treatment than from other forms of radiation.
