Stereotactic radiosurgery is a very precise form of therapeutic radiation that can be used to treat abnormalities in the brain and spine, including cancer, epilepsy, trigeminal neuralgia and arteriovenous malformations.
The specialized equipment focuses many small beams of radiation on a tumor or other target. Each beam has very little effect on the tissue it passes through, but a targeted dose of radiation is delivered to the site where all the beams intersect .
