 What Is Gamma Knife Radiosurgery?

Gamma Knife radiosurgery is a procedure that requires little or no anesthesia and offers a fast recovery time—so you can get back to your life fast. The "knife" refers to 192 precise beams of radiation that meet and create a powerful dose of concentrated radiation. It attacks tumors and abnormalities, shrinking them over time or stopping their growth altogether. This targeted approach all takes place with no damage to surrounding, healthy tissue.

Leksell Gamma Knife Icon System

At UW Medicine, we use the latest in Gamma Knife technology: the Gamma Knife Icon system. Patients may wear a head frame using four pins or screws to hold the frame in place. This allows treatment to be completed in one day. It is the best option for some condiitions, including when there is more than one area in the brain to be treated. Sedation is used for frame placemnt and is individualized for patients' needs.​

With the Icon system, another option is for treatment with a specially-fitted face mask. Our mask-based treatment is completely painless, no pins are required, and treatment may be completed in up to 5 days.

Your care team will explain all options in detail and help you understand what is best for you.

The UW Medicine Gamma Knife Center’s dedicated physicians, nurses and care coordination team provide sensitive, compassionate, lifetime patient support with nearly 100 percent ​patient satisfaction. The team facilitates ongoing follow-up with patients and referring providers.
