Gamma Knife® surgery Gamma Knife surgery is a non-invasive method for treating brain disorders. It is defined as the delivery of a single, high dose of radiation to a small and critically located intracranial volume through the intact skull. After Gamma Knife surgery, the patient normally leaves the hospital the same or the following day, making it a very cost effective alternative to open surgery. Since its introduction, Leksell Gamma Knife® has revolutionized the treatment of brain disorders. Today, this treatment is offered by hundreds of leading hospitals and clinics around the world. Around 40,000 patients undergo Gamma Knife surgery every year, and this unique procedure has earned an outstanding scientific track record with thousands of peer reviewed articles on treatment efficacy, improved quality of life for patients and cost efficiency. ********
