Accuray Inc was incorporated in California in 1990 and commenced operations in 1992. The Company was reincorporated in 2007 in Delaware. The Company is a radiation oncology company. It develops, manufactures, sells and supports precise treatment solutions. The Company's technologies are designed to deliver radiosurgery, stereotactic body radiation therapy, intensity modulated radiation therapy and image guided radiation therapy and adaptive radiation therapy. It operates in Europe, Middle East, India and Africa, Asia Pacific and Japan. Its suite of products includes the CyberKnife Systems and the TomoTherapy Systems. The CyberKnife Systems are fully robotic stereotactic radiosurgery systems, or SRS and stereotactic body radiation therapy systems, or SBRT used to treat multiple types of cancer and tumors throughout the body. The CyberKnife Systems automatically track, detect and correct for tumor and patient movement in real-time during the procedure, enabling delivery of precise, high dose radiation with sub-millimeter accuracy while patients breathe normally. Treatment with the CyberKnife Systems requires no anesthesia, and can be performed in one to five staged treatment sessions on an outpatient basis. In addition, the CyberKnife Systems are designed to minimize many of the risks and complications that are associated with other treatment options. The CyberKnife Systems include: the CyberKnife G4, which includes the Fixed collimator; CyberKnife VSI System, which includes the Fixed and Iris collimators and the new CyberKnife M6 Series System, that comes in configurations that have the option of Fixed collimator, Iris collimator, and a MultiLeaf collimator, or MLC. The TomoTherapy Systems are used to treat cancers and tumors, and enable efficient daily imaging to ensure the accuracy of the patient position before each treatment delivery. The TomoTherapy Systems operate on ring gantries and combine integrated CT imaging with intensity modulated radiation therapy or IMRT, which is designed to deliver radiation treatments with speed and precision while reducing radiation exposure to surrounding healthy tissue. The TomoTherapy Systems include the Hi-Art System, delivering CT-guided, helical IMRT; the TomoHD System, which includes both the TomoHelicalTM and TomoDirectTM treatment modalities and the Tomo H TM Series Systems that come in configuration options of TomoHTM, TomoHD and TomoHDATM and which includes one or more options such as TomoHelicalTM, TomoDirectTM, High Performance VoLo TM Planning and TomoEdge Dynamic Jaws. Its competitors are Elekta AB and Varian Medical Systems, Inc, Mitsubishi Heavy Industries, BrainLAB AG, and ViewRay Inc.
