Accuray Incorporated, incorporated in 1990, has developed a robotic radiosurgery system, CyberKnife Robotic Radiosurgery System, designed to treat solid tumors anywhere in the body as an alternative to traditional surgery. Its CyberKnife system represents the radiosurgery systems, combining continuous image-guidance technology with a compact linear accelerator (linac). Its image-guidance technology enables the system to acquire images to track a tumor's location and transmit any position corrections to the robotic arm prior to delivery of each dose of radiation. Its linac is a compact radiation treatment device that uses microwaves to accelerate electrons to create high-energy, X-ray beams to destroy the tumor. The CyberKnife system autonomously tracks, detects and corrects for tumor and patient movement in real-time during the procedure, enabling delivery of precise, high-dose radiation with sub-millimeter accuracy. The CyberKnife procedure requires no anesthesia. As of June 30, 2010, 206 CyberKnife systems were installed, including 132 in the Americas, three of which are pursuant to its shared ownership program, 45 in Asia and 29 in Europe. In June 2011, the Company acquired TomoTherapy Incorporated.
The Company’s principal product is the CyberKnife system. It also offers optional hardware and software, technical enhancements and upgrades to the CyberKnife system, as well as service contracts and training to assist customers in realizing the benefits of the CyberKnife system. The CyberKnife system combines continuous image-guidance technology with a compact linear accelerator mounted on a computer-controlled manipulator arm to precisely deliver high doses of radiation to the tumor from numerous directions during treatment. Its patented image-guidance technology correlates low dose, real-time treatment X-rays with images previously taken with a computed tomography (CT) scan of the tumor and surrounding tissue to precisely direct each beam of radiation.
The Company’s components and technologies of the CyberKnife system and the CyberKnife VSI system include CyberKnife VSI System, Robotic manipulator, X-ray sources, Image detectors, Synchrony Respiratory Tracking System, Xsight Spine Tracking System, Xsight Lung Tracking System, RoboCouch Patient Positioning System, Standard Treatment Couch, Xchange Robotic Collimator Changer, Iris Variable Aperture Collimator, 4D Treatment Optimization and Planning System, InTempo Adaptive Imaging System, MultiPlan Treatment Planning System, MultiPlan MD Suite, CyberKnife Data Management System. The CyberKnife system are used to target tumors that cannot be treated with traditional surgical techniques.
The image detectors capture high-resolution anatomical images throughout the treatment. The Standard Treatment Couch is used to automatically align the patient for treatment. The Company’s 4D Treatment Optimization and Planning System optimizes treatment by taking into account the movement of the tumor, as well as the movement and deformation, or change in shape, of the surrounding tissue, thereby minimizing margins and radiation exposure to healthy tissue. The InTempo System is a time-based target tracking technology used to compensate for intrafraction prostate motion during treatment delivery. The MultiPlan MD Suite solution allows remote users to perform pre-planning preparation and post-planning review of treatment plans. The CyberKnife Data Management System provides storage and processing of the patient data that is generated as the patient progresses through the CyberKnife planning and treatment workflow.
The Company competes with Elekta AB, BrainLAB AG, Integra Life Sciences Holding Corporation, Siemens, Varian Medical Systems, Inc. and TomoTherapy Incorporated.
