Expand Treatment Options And Your Practice With The World's Most Accurate Radiosurgery Device

World’s First and Only Full-Body Radiosurgery System

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 anatomy. In this way, the CyberKnife automatically detects and compensates for patient movement in real time, with updated image guidance at every beam position.

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.

“Treatment with the CyberKnife is really medicine in the ideal--it involves a true team collaboration, with the health and welfare of our patient as its central focus.”

Mark Brenner, M.D.
Chief of Radiation Oncology Sinai Hospital of Baltimore

CyberKnife Defines Radiosurgery
The CyberKnife® System from Accuray™ is the world’s most accurate radiosurgery instrument. It establishes a new gold standard in radiosurgery by precisely ablating tumors and other lesions anywhere in the body, with submillimeter Total Clinical Accuracy*.

Using image guidance, robotics, and dynamic respiratory motion tracking, the CyberKnife System delivers superior accuracy and conformality. In fact, as the first device to enable full-body dynamic radiosurgery, the CyberKnife is making possible effective new treatments in clinical areas such as spine, lung, liver, pancreas, pelvic tumors, and prostate.

*Total Clinical Accuracy = sum of all clinically relevant errors.
