Gamma Knife®

Gamma Knife® is the first stereotactic radiosurgery technology invented and remains the "gold standard" for treating tumors and other abnormalities in the brain and upper neck that were previously considered inoperable.Gamma Knife uses 192 beams of highly focused gamma rays to irradiate the target from every direction. Each low-intensity beam of radiation is too weak by itself to harm the tissue through which it passes. Damage occurs only at the spot where all the beams converge.

With the help of a computer and the latest imaging technology (MRI, CT or angiography), physicians can identify the exact spot with pinpoint accuracy. Since no incisions are required in radio-surgery, the chance of complications is substantially reduced. Saint Agnes Medical Center is one of only 240 institutions worldwide using Gamma Knife, and among an elite group using the newest and most precise version − the Perfexion.
