St. Louis University Hospital Purchases Second CyberKnife(R) System

Major Academic Center Expands Cancer Treatment Access to Local Community

SUNNYVALE, Calif., March 3 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, announced today that St. Louis University Hospital has purchased a second CyberKnife(R) Robotic Radiosurgery System for its western satellite location in Lake St. Louis, Mo. This satellite facility will allow those living in the rural communities easier access to the CyberKnife System's unique capabilities.

Saint Louis University Hospital acquired its first CyberKnife System in 2004 and has been using it to treat tumors in the brain, lung, pancreas and liver. A Certificate of Need (CON) meeting in Jefferson City, Mo., approved the hospital's purchase of a second CyberKnife System. Along with 36 other states, Missouri law requires hospitals to secure a Certificate of Need (CON) by demonstrating there is an unmet need for particular capital equipment or expansion before permission can be granted.

"St. Louis University Hospital is the most recent in a long line of centers that have elected to purchase a second CyberKnife System," said Eric P. Lindquist, senior vice president and chief marketing officer of Accuray Incorporated. "This further validates that demand for radiosurgery is exceeding the capacity of one CyberKnife System, supporting the purchase of multiple Systems."

Saint Louis University Hospital was the first facility in Missouri to begin using the CyberKnife System. Since then Mercy St. John's Hospital in Springfield, Mo., has also acquired a CyberKnife System.

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.
