CyberKnife was invented at Stanford Health Care and is used to treat a variety of conditions, with one of the most technologically-advanced forms of radiosurgery. CyberKnife stereotactic radiosurgery uses computer technology that allows doctors to deliver radiation with unprecedented precision. Unlike other radiosurgery technologies, the CyberKnife does not use uncomfortable screws or frames to immobilize patients during treatment.

The CyberKnife is capable of treating tumors anywhere in the body. At Stanford, CyberKnife technology is commonly used for treatment of tumors and conditions of the brain and spine, in addition to cancers of the pancreas, prostate, liver, and lungs.
