 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 Leksell Gamma Knife Icon system. Patients may wear a specially-fitted head mask for the procedure, which is painless. With our procedure, no incisions are required.

 Note: Typically, gamma knife radiosurgery uses a head frame instead of a mask. For some conditions, this may still be the best option. Your care team will explain all procedures in detail, and help you understand what is best for you.
