CyberKnife accuracy for Accuray

Accuray Incorporated, a specialist in image-guided full-body radiosurgery, has completed the purchase of certain assets of the High Energy Systems (HES) division of American Science and Engineering (AS&E), thereby acquiring exclusive rights to manufacture, market and sell X-band linear accelerators used in Cyberknife technology for medical applications.

As such, Accuray now has full control over the technology and production of the X-band linear accelerator systems, which are used to produce the radiation beam that destroys cancer cells.

The CyberKnife stereotactic radiosurgery system, developed in cooperation with Stanford University, is a non-invasive, 100% frameless image-guided radiosurgery system that ablates tumours and other lesions anywhere in the body without invasive surgery. It treats in single or staged (typically two to five) ses-sions and monitors internal reference points in the anatomy, such as skeletal landmarks or small implanted markers, to correct for patient movement in real-time during actual treatment. It delivers multiple beams of precisely directed radiation that converge upon the tumour while minimizing injury to surrounding healthy tissue. It is the only system in the world that integrates real-time image guidance and robotic delivery of radiation for proven sub-millimetre 'total clinical accuracy'.
