SUNNYVALE, CA and NEW YORK, 27 June 2017 – Accuray Incorporated (NASDAQ: ARAY) and Montefiore Einstein Center for Cancer Care (MECCC), part of the Montefiore Health System (MHS), announced today that Montefiore doctors have treated the first cancer patients in New York with the advanced Radixact™ Treatment Delivery System. The system was designed to deliver image-guided intensity-modulated (IG-IMRT) radiation therapy, an extremely precise form of radiation therapy. Montefiore is the only hospital in New York State, and in the greater New York area, to have this equipment.

The Radixact System is the next generation TomoTherapy® platform developed to enable doctors to more efficiently and effectively deliver precise radiation treatments to more patients with cancer every day. What makes the Radixact technology different from conventional radiation systems is the integration of a CT scanner with the radiation therapy delivery system. The built-in CT scanner performs daily imaging before each treatment session to determine the shape and position of the tumor. This allows for accurate and precise tumor targeting, while reducing the radiation dose to normal, healthy tissue. Only then, is radiation delivered from 360 degrees around the patient's body allowing for treatment of any target, irrespective of its length.

Daily pretreatment imaging, coupled with the System's Accuray Precision™ Treatment Planning System and PreciseART™ Adaptive Radiation Therapy software, informs precise treatment planning and mid-course decision-making, so clinical teams can instantly adapt therapy to:
Changes in tumor size, shape and location
Subtle changes in the location of organs and other healthy tissue, due to weight gain or loss
Identifying and correcting for any variations in patient positioning, as well as biological changes, ensures the continued precision and safe delivery of the radiation dose to the target area, resulting in fewer long term side effects. The Radixact System is capable of treating all standard radiation therapy indications including breast, head and neck, lung, and prostate cancers, in addition to complex treatments such as total marrow irradiation. The Montefiore patients were treated for prostate cancer and plans are also in place to use the System for patients with Ob/Gyn related cancers and head and neck cancers, as these often require alterations to therapy mid-course due to changes in tumor size, location and individual weight.
