Dignity Health Bay Area’s CyberKnife facility serves patients from Saint Francis Memorial Hospital, Sequoia Hospital, and St. Mary’s Medical Center.

What Is CyberKnife?

CyberKnife is a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumors anywhere in the body including the brain. 

This advanced technology delivers a specialized form of radiation therapy called stereotactic radiosurgery, or stereotactic body radiation therapy. It is comprised of a compact linear accelerator, a machine that generates a radiation beam, attached to a highly maneuverable robotic arm. It’s an outpatient treatment, completely painless, and extremely accurate. 

The CyberKnife features a device that controls the width of the radiation beams delivered during treatment, allowing our clinical experts to vary the beam size and treat a larger variety of tumors throughout the body including brain tumors, lung cancer, and prostate cancer.
