History
Accuray grew out of the development of precision radiation-treatment technology in the 1990s and built its CyberKnife product family around image-guided robotic radiosurgery. The system uses imaging and dynamically directed radiation delivery to provide highly focused treatments. As radiation oncology increasingly adopted image guidance, stereotactic treatment and patient-motion management, Accuray broadened its activities into a wider range of radiation-therapy solutions. The company later expanded into the helical tomotherapy field through the development and integration of the TomoTherapy technology platform, leading to the Radixact product family. Its business subsequently extended beyond equipment sales to treatment-planning software, image guidance, system upgrades, maintenance and clinical support. Accuray now operates as Accuray Incorporated and is listed on Nasdaq. Product portfolios, indications and geographic availability depend on local medical-device approvals.
