The CyberKnife VSI System is a computer controlled medical systems for planning and performing minimally invasive stereotactic radiosurgery and precision radiotherapy using a treatment radiation generator, linear accelerator, manipulator (robot), and a target locating subsystem to accurately deliver radiation to the treatment target. The target locating system provides X-rays of the treatment area taken by a diagnostic X-ray system that lets the user know the position of the target. The CyberKnife VSI Systems use skull tracking, fiducial tracking, Xsight® Spine Tracking, Xsight® Lung Tracking, and Synchrony® Respiratory Tracking for dynamic positioning and pointing of the linear accelerator. The system uses a 6 MV linear accelerator to provide a dose rate up to 1000 MU/minute.
An assembly of devices designed to produce high-energy electrons to yield high-energy x-rays used for therapeutic applications, primarily to treat cancer. It provides a uniform radiation field of uniform intensity and predictable energy level, in a beam with well defined dimensions. The principle of operation is linear acceleration of electrons by means of electromagnetic (EM) microwaves. The output is used as a treatment beam on the patient, either directly or after passing a suitable target. The system typically includes signal analysis and display devices, patient and device supports, and software.
