Gamma Knife®

Gamma Knife is a non-invasive stereotactic radiosurgery instrument that doesn’t involve either a scalpel or incision – it is not a knife at all. Instead, Gamma Knife uses up to 201 precisely focused beams of radiation to control malignant and nonmalignant tumors, as well as vascular and functional disorders in the brain, without harming surrounding healthy tissue.

Patients are typically in and out of the hospital in a day’s time – and back to a normal routine soon after treatment. Gamma Knife radiosurgery may be used in place of, or in addition to, traditional surgery or whole brain radiation, depending on a patient’s diagnosis.

Gamma Knife radiosurgery is recognized worldwide as the preferred treatment for brain tumors, arteriovenous malformations and brain dysfunctions such as trigeminal neuralgia. The Gamma Knife offers a non-invasive alternative for many patients for whom traditional brain surgery is not an option. Gamma Knife surgery removes the physical trauma and the majority of risks associated with conventional surgery.
