The Gamma Knife is a sophisticated instrument that pinpoints and delivers precise beams of radiation to tumors and other brain abnormalities. This 20 ton machine offers a noninvasive alternative to open brain surgery that eliminates the risk of surgical complications. It enables neurosurgeons and radiation oncologists to accurately target the treatment area in the brain. The Gamma Knife also allows doctors to treat previously inoperable lesions, while minimizing damage to surrounding normal tissue.
This surgery-free process is exceptionally effective at reducing or eliminating brain tumors, blood vessel abnormalities, functional disorders and other conditions.
The Gamma Knife is used on 40,000 adults and children worldwide each year. See Neurological Diseases Treated.
Gamma Knife treatment can be used alone or as an additional therapy for patients who have undergone brain surgery, interventional neuroradiology, conventional radiation therapy or chemotherapy.
