Gamma Knife Details
Gamma knife surgery is a fully automated form of surgery that uses radiation to treat most often malignant tumors and other abnormalities in the brain. This type of surgery is used to pinpoint areas that cannot be reached via traditional surgical methods or to target tumors only millimeters in diameter. Over 100 low-intensity beams of highly-focused gamma rays are made to converge on a single pre-determined spot via previous diagnostic procedures and scans. The procedure is largely non-invasive and is usually an outpatient treatment but patients may require an overnight stay for continued monitoring.
