Stereotactic radiosurgery is not really surgery. Rather, it's a form of radiation therapy that uses 3-D computer imaging to attack tumors and lesions in the brain and other areas of the body with an extremely precise dose of radiation. Linear accelerators offer potential advantages to some patients over other stereotactic radiosurgery technologies such as the Gamma Knife, notably the ability to treat tumors throughout the entire body, not just those in the brain.
MultiCare is the first health system in the South Puget Sound region to offer image-guided, stereotactic linear accelerator treatment, on the Varian Trilogy System, for treating cancers and other appropriate conditions. It can be beneficial for treating tumors that would be difficult or dangerous to operate on given their location in the brain.
