CyberKnife radiosurgery is a robotic surgery device that uses a linear accelerator mounted on a computer-controlled robotic arm to treat tumors throughout the body that are often unreachable by conventional surgery. The CyberKnife uses image-guided robotics to destroy tumors and other lesions with multiple beams of high-energy radiation. The cumulative effect of all the beams at the target results in the lesion receiving a very high dose of radiation while nearby normal tissue is preserved. Cyberknife radiosurgery is sufficiently precise to match the shape of small, complex tumors located in critical structures.

The CyberKnife System, designed by Accuray, combines two advanced technologies to deliver a revolutionary, frameless radiosurgery. The first innovation is a lightweight linear accelerator mounted on a multi-jointed robotic arm. This flexible robotic arm provides access to unreachable tumors and helps reduce harm to critical structures surrounding the lesion such as vital organs and tissues. The second innovation is an image guidance system. This can compensate for patient movement, and allow radiation to be delivered without using rigid immobilization, such as a head frame.
