SUNNYVALE, Calif., Oct. 31 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), has been named to Deloitte's Technology Fast 50 Program for Silicon Valley Scientific/Medical Equipment and Biotechnology companies. This year's Silicon Valley Technology Fast 50 program is co-presented by Deloitte, Silicon Valley Bank, Korn/Ferry International, Cooley Godward Kronish LLP, Cornish & Carey Client Solutions, and ABD Insurance and Financial Services - A Wells Fargo Company. Rankings are based on the percentage revenue growth over five years from fiscal year 2003-2007.

"Deloitte's Silicon Valley Technology Fast 50 companies have shown the strength, vision and tenacity to succeed in today's very competitive technology environment," said Mark Jensen, Managing Partner, National Venture Capital Services, Deloitte & Touche LLP, in Silicon Valley. "We applaud the successes of Accuray Incorporated and acknowledge it as one of the very few to accomplish such a fast growth rate over the past five years."

Accuray Incorporated's 5,000 percent increase in revenues from fiscal year 2003 to 2007 resulted in a fifth place ranking in the Technology Fast 50 for Silicon Valley.

"We are proud of Accuray's consistent growth over the past five years and the impact that the CyberKnife System has had on the cancer community," said Euan S. Thomson, president and chief executive officer of Accuray. "We are honored to be recognized as one of the fastest growing companies in an area as flourishing as the Silicon Valley."

To qualify for the Technology Fast 50, companies must have had operating revenues of at least $50,000 in fiscal year 2003 and $5,000,000 in fiscal year 2007, be headquartered in the San Francisco Bay Area, and be a company that owns proprietary technology or proprietary intellectual property that contributes to a significant portion of the company's operating revenues; or devotes a significant proportion of revenues to the research and development of technology.
