Gamma Knife
With unparalleled precision, the Gamma Knife delivers powerful doses of
radiation to inaccessible or inoperable lesions in the brain. Surgery with the
Gamma Knife is often referred to as "surgery without a scalpel," because it
involves no incision, minimal pain and greatly reduced risk for the patient.
The Gamma Knife is not a knife at all, but a radiosurgery device that enables
doctors to treat deep-seated intracranial lesions without the risks of
open-skull surgery. The "blades" of the Gamma Knife are beams of gamma radiation
programmed to bombard the lesion when they intersect. Independently, however,
these beams pass harmlessly through the skull and surrounding tissue.
This revolutionary tool offers new hope to patients with inoperable conditions
such as arterio-venous malformations and brain tumors.
