Leading Neurosurgical Center in Moscow Purchases CyberKnife System to Expand Ability to Treat Brain and Spinal Tumors

Installation at Burdenko Institute of Neurosurgery will be Accuray's Second in Russia

SUNNYVALE, Calif., Aug. 7 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, announced today that the Burdenko Institute of Neurosurgery in Moscow has purchased a CyberKnife(R) Robotic Radiosurgery System. When the system is installed, the Burdenko Institute will become the second facility in Russia to offer advanced robotic radiosurgery treatments.

The CyberKnife System will enable the Burdenko Institute to expand its ability to treat tumors and other diseases of the brain and spine. With real-time image guidance and the ability to adjust for patient and tumor movement during treatment, clinicians are able to deliver radiation with extreme precision without requiring patients to be positioned in uncomfortable frames. Because it is non-invasive and does not require the use of frames, the CyberKnife System is ideal for those users who wish to deliver fractionated intracranial treatments.

"The Burdenko Institute is world renowned for its expertise in the treatment of neurological conditions," said Eric P. Lindquist, senior vice president and chief marketing officer of Accuray Incorporated. "With the addition of a CyberKnife System, clinicians there will be able to expand their radiosurgical capabilities, while offering patients a viable, non-invasive alternative to traditional surgery."

Established in 1932 as the Moscow Institute of Neurosurgery the facility focused specifically on neurosurgery. The institute was later renamed for Nikolai Nilovich Burdenko, who is regarded as the founder of Russian neurosurgery. The Burdenko Institute currently is led by Alexander N. Konovalov, M.D., Ph.D., who has served as its director for more than 32 years and is one of the foremost figures in Russian neurosurgery.

The Burdenko Institute will receive its CyberKnife System by the end of the 2008 calendar year through local distributor Newstep Ltd.

About the CyberKnife(R) Robotic Radiosurgery System

The CyberKnife Robotic Radiosurgery System is the world's only robotic radiosurgery system designed to treat tumors anywhere in the body non-invasively. Using continual image guidance technology and computer controlled robotic mobility, the CyberKnife System automatically tracks, detects and corrects for tumor and patient movement in real-time throughout the treatment. This enables the CyberKnife System to deliver high-dose radiation with pinpoint precision, which minimizes damage to surrounding healthy tissue and eliminates the need for invasive head or body stabilization frames.
