Stereotactic radiosurgery uses numerous precisely focused radiation beams to treat tumors and other problems in the brain and other parts of the body.

Stereotactic radiosurgery focuses many beams of radiation at the tumor, delivering high doses of radiation to the target area with minimal exposure to the healthy tissue that surrounds it. Treatment to the brain and spine is typically completed in a single session. Treatments to other parts of the body may involve multiple sessions.

When doctors use stereotactic radiosurgery to treat tumors in areas of the body other than the brain, it's sometimes called stereotactic body radiotherapy or stereotactic ablative radiotherapy.

Stereotactic radiosurgery is used to treat:

Doctors use two types of technology to deliver stereotactic radiosurgery. A Gamma Knife machine uses gamma rays to treat cancerous and noncancerous brain abnormalities. A linear accelerator (LINAC) machine uses X-rays to treat cancerous and noncancerous abnormalities in the brain and other parts of the body.
