Gamma Knife

Ultra-powerful, ultra-precise radiation beams to destroy tumors or lesions within the brain.

The Gamma Knife uses ultra-powerful, ultra-precise radiation beams to destroy tumors or other lesions within the brain. A total of 201 beams of radioactive cobalt-60 can be individually programmed to deliver targeted doses through a special head frame and helmet. Treatment is delivered only at the precise point where the beams converge.

Exclusively provided at Methodist Estabrook Cancer Center

The Gamma Knife is called the most accurate and effective option available and the pinnacle of performance for non-invasive stereotactic radiosurgery, by more than 2,000 peer-reviewed papers. Methodist Estabrook Cancer Center is home to the metro area's only Elekta Leksell Gamma Knife®.
