Why is CyberKnife Radiosurgery Different?

CyberKnife® Defines Radiosurgery

Using image-guidance, robotics and dynamic respiratory motion tracking, the CyberKnife® System delivers superior accuracy and conformality to lesions throughout the body. Developed by Accuray and FDA approved for full body use in 2001, it is the first device to enable full-body dynamic radiosurgery. CyberKnife® is making possible effective new treatments in clinical areas such as spine, lung, liver, pancreas and prostate lesions.

Full-Time Robotics Technology

The CyberKnife® System utilizes a robotic manipulator to move the compact linear accelerator with six degrees of freedom. With this range of motion, the robotic manipulator is capable of positioning the linear accelerator to an infinite number of beam positions and orientations. This creates the ability to accurately adjust the beam to react to three-dimensional translational and rotational target volume displacements, providing treatment flexibility and accuracy that is unsurpassed in radiosurgery. Such versatility allows both non-isocentric and isocentric treatment of lesions and enables superior conformality.

Dynamic Motion Tracking™

The CyberKnife® System tracks position in tumors that move with respiration in real time, by synchronizing radiation delivery to the motion of the respiratory cycle, using a sophisticated combined optical and radiographic tracking system. This 4D tracking capability is unique to the CyberKnife® and not only makes treatment with the CyberKnife® significantly more comfortable for patients, but safer, faster and more accurate as well.

Real-Time Image Guidance Throughout the 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® systems tracks internal reference points. In this way the CyberKnife® automatically detects and compensates for patient and tumor movement in real time, with updated image guidance at every beam position
