Accuray Signs Distribution and Co-Marketing Agreement with Siemens

Agreement Enables Integration of Diagnostic CT Imaging and Robotic Radiosurgery Technology in the Treatment Room

SUNNYVALE, Calif., April 11 (HSMN NewsFeed) -- Accuray Incorporated (Nasdaq: ARAY ), a global leader in the field of radiosurgery, today announced that it has signed a co-marketing and distribution agreement with Siemens Medical Solutions USA, Inc. The agreement enables Accuray to integrate its CyberKnife® Robotic Radiosurgery System and RoboCouch(TM) Patient Positioning System with a Siemens SOMATOM® computed tomography (CT) scanner with a sliding gantry configuration. The combination of these technologies in the treatment room further enhances visibility of internal structures at the time of treatment.

Unlike other in-room imaging solutions, the Siemens SOMATOM 3D and 4D system is designed to ensure clinicians have access to the highest diagnostic quality images and 4D image data during patient setup. Other radiation therapy systems have begun to offer slower, lower quality imaging techniques such as cone beam imaging to verify patient position. In contrast, the CyberKnife System with Siemens CT sliding gantry solution enables faster, higher resolution imaging setup. This, combined with the CyberKnife System's ability to continually track, detect and correct for tumor and patient movement, enables the CyberKnife System to deliver enhanced treatment quality and throughput.

The clinical benefits of the in-room diagnostic CT system are realized mainly in the treatment of tumors that move with respiration, such as lung, liver and pancreas, as well as prostate tumors, which are impacted by bowel and bladder function. Unlike cone beam CT, diagnostic CT provides higher resolution imaging and allows for differentiation of soft tissue structures. In the treatment of prostate tumors, this enhanced ability allows for visualization of physiological changes like rectal or bladder filling, to ensure the organs haven't moved into the treatment field since the preliminary planning CT. Additionally, for tumors that move with respiration, the addition of in-room 4D CT helps to account for tumor motion and deformation between the planning CT and the CT on the day of treatment.

"This agreement with Siemens further validates Accuray's commitment to providing innovative solutions that meet clinicians' needs," said Euan S. Thomson, Ph.D., president and chief executive officer of Accuray. "By combining the best systems in in-room imaging and robotic radiosurgery, we are able to offer clinicians a more efficient means for positioning patients and ensuring extreme accuracy in targeting their tumors."

About the CyberKnife® Robotic Radiosurgery System

The CyberKnife System represents the next generation of radiosurgery systems, combining continuous image-guidance technology with a compact linear accelerator that has the flexibility to move in three dimensions according to the treatment plan. This combination, which is referred to as intelligent robotics, extends the benefits of radiosurgery to the treatment of tumors anywhere in the body. 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 typically with sub- millimeter accuracy.

About Accuray

Accuray Incorporated (Nasdaq: ARAY ), based in Sunnyvale, Calif., is a global leader in the field of radiosurgery. Its CyberKnife System is the world's first and only commercially available intelligent robotic radiosurgery system designed to treat tumors anywhere in the body, typically with sub- millimeter accuracy. To date, it is estimated that the CyberKnife System has treated more than 20,000 patients worldwide. For more information, please visit www.accuray.com.
