Accuray Launches New Configuration for CyberKnife System to Offer Hospitals Installation Flexibility

New Footprint Enables Hospitals to Save Construction Costs and Speed Deployment Time by Placing CyberKnife System in Existing Vault

SUNNYVALE, Calif., Sept. 17 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, announced today that it is offering a new layout for the CyberKnife(R) Robotic Radiosurgery System treatment vault which will enable installation of the System into most existing conventional gantry LINAC vaults. With this new, smaller footprint, hospitals will be able to save hundreds of thousands of dollars or more on construction and shielding costs, and begin treating patients more quickly.

"Many of our potential customers have expressed interest in a CyberKnife System to replace an aging gantry LINAC. However, space constraints in existing facilities or the inability to build a new facility to house the CyberKnife System have impacted their final decision," said Eric P. Lindquist, senior vice president and chief marketing officer at Accuray. "Taking advantage of existing treatment room design and shielding, the new layout should enable an accelerated go-live schedule, allowing sites to begin treating patients within a significantly shorter period of time."

While nearly identical feature-wise to the standard CyberKnife vault layout, the gantry LINAC vault layout reduces both treatment vault and equipment room footprints, giving customers more flexibility in where they can place a CyberKnife System. Installation of the CyberKnife System in a gantry LINAC vault is enabled with minimal-to-no additional shielding and the redesign of treatment beams to avoid secondary shielding walls.

With nearly identical capabilities to that of the CyberKnife System in a standard vault layout, the gantry LINAC vault layout requires 34 percent less vault space. With only a limited reduction in robotic maneuverability, the vast majority of functionality is retained and is compatible with nearly all CyberKnife System product options.

Accuray will highlight its new vault layout at the company's booth #1701 during the 50th American Society for Therapeutic Radiology & Oncology (ASTRO) Annual Meeting September 21-25, 2008 in Boston.

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.
