How CyberKnife Works

Real-Time Image Guidance throughout Treatment: Image-guided CyberKnife^® radiosurgery is non-invasive and 100% frameless. Since treatments can be delivered in single or fractionated sessions, CyberKnife offers optimum protection for adjacent critical structures. Unlike traditional radiosurgery devices, the CyberKnife System tracks internal reference points in the bony anatomy and fiducials. In this way, the CyberKnife automatically detects and compensates for patient movement in real time, with updated image guidance at every beam position.

the CyberKnife System works.

Dynamic Motion Tracking: The CyberKnife System with the Synchrony Respiratory Tracking System is the only radiosurgery technology in the world that tracks tumor position in real time, by synchronizing radiation delivery to the motion of the tumor throughout the respiratory cycle. Accuray's advanced image-guidance technology locates the tumor while the Synchrony System continuously tracks the patient's respiratory motion. This 4D tracking capability not only makes treatment with the CyberKnife System significantly more comfortable for patients, but safer, faster, and more accurate as well.

Full-Time Robotics Technology : The CyberKnife utilizes a robotic manipulator to move the system's compact linear accelerator with six degrees of freedom. With this range of motion the robotic manipulator is capable of positioning the linac to an infinite number of beam positions and orientations, providing treatment flexibility that is unsurpassed in radiosurgery. Such versatility allows both non-isocentric and isocentric treatment of lesions and enables superior conformality.

Submilliter Total Clinical Accuracy: A new gold standard in radiosurgery precisely ablates tumors and other lesions anywhere in the body.

Superior accuracy and conformality through the use of image guidance, robotics, and dynamic respiratory motion tracking.
