Gamma Knife Radiation surgery is an alternative to traditional brain surgery and whole brain
radiation therapy for the treatment of complex, difficult brain conditions. It is a non-invasive
stereotactic radiosurgery instrument that involves no scalpel or incision – it’s not a knife at all.
Instead, the Gamma Knife uses up to 201 precisely focused beams of radiation to control malignant
and non-malignanttumors, as well as vascular and functional disorders in the brain, without
harming surrounding healthy tissue. It is done as an ambulatory procedure and patients can regain
back to their normal routines soon after treatment.
