The CyberKnife^® Robotic Radiosurgery System is the world's first and only commercially available radiosurgery system designed to treat tumors anywhere in the body with sub-millimeter accuracy. It uses a combination of image guidance technology and computer controlled robotics to continuously track, detect and correct for tumor and patient movements throughout the treatment. Because of its extreme precision, the CyberKnife System does not require invasive head or body frames to immobilize the patient for tumor tracking.

During treatment, the CyberKnife System correlates live radiographic images with pre-treatment CT scans in real time to determine patient and tumor position repeatedly over the course of treatment.

With the CyberKnife System’s revolutionary Xsight^® Spine Tracking System it is now possible to treat tumors in or near spinal structures without implanting radiographic markers or fiducials.

The CyberKnife System’s Synchrony^® Respiratory Tracking System technology allows patients to breathe normally throughout their treatment without breath-holding or gating techniques enabling the system to continuously track, detect and correct for tumor and patient movement throughout the treatment.
