How CyberKnife Works

CyberKnife uses image guidance technology and computer controlled robotics to continuously track, detect and correct for tumor and patient movement throughout the treatment. Because of its extreme precision, CyberKnife does not require invasive head or body frames to stabilize patient movement, vastly increasing the system's flexibility.
Unlike traditional radiosurgery systems that can only treat tumors in the head and neck, CyberKnife can treat tumors both intracranial (inside the brain) and extracranial (outside the brain). In fact, extracranial treatments currently represent more than 50 percent of CyberKnife procedures in the United States, including those of the spine, lung, prostate, liver and pancreas.
CyberKnife provides an additional option to many patients diagnosed with previously inoperable or surgically complex tumors.
