About the CyberKnife® System

The CyberKnife® System is manufactured by Accuray Incorporated. Accuray is known for its precise, innovative tumor treatments and its focus on customer satisfaction. In a survey of radiation therapy medical professionals that use Accuray products, 84 percent were highly satisfied with the accuracy and precision of the Accuray systems. Comparatively, among radiation therapy medical professionals who use the other radiation delivery systems available in the U.S., only 60 percent to 70 percent were highly satisfied with the accuracy and precision of the systems manufactured by other companies.1

What is the CyberKnife System?

The CyberKnife System is a non-invasive2 treatment for cancerous and non-cancerous tumors and other conditions where radiation therapy is indicated. It is used to treat conditions throughout the body, including tumors of the prostate, lung, brain, spine, head and neck, liver, pancreas, kidney, and certain gynecologic indications, and can be an alternative to surgery or for some patients who have inoperable or surgically complex tumors. What makes the CyberKnife System unique is that it is the only fully robotic radiation delivery system. The robotic design, coupled with real-time imaging, enables the CyberKnife System to deliver a maximum dose of radiation directly to the tumor from many different angles with sub-millimeter precision. The CyberKnife System does this by tracking and adjusting for tumor or patient movement during treatment to minimize radiation exposure to healthy organs and tissues.

  2. Radiation therapy is completely non-invasive. In some cases, tiny gold markers (fiducials) that help distinguish the tumor from non-cancerous soft tissue are implanted with a minimally invasive procedure.
