T-Ray Science Announces Management Appointments

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 27, 2010) - T-Ray Science, Inc. (TSX VENTURE: THZ) (“T-Ray” or the “Company”), a pioneer in the development of a new modality for early skin cancer detection, announced today Tom Walker has been promoted to Chief Business Development Officer and Jeff Hendrikse has been appointed to Vice President of Product Development.

“Our ability to attract and retain high quality executives with relevant industry experience is key to our success in realizing our product development milestones. We intend to build a world class company and Tom and Jeff have the experience we need to manage the rapid growth that lies ahead,” said Thomas Braun, CEO of T-Ray.

Chief Business Development Officer

With over 25 years of North American and International experience in healthcare markets, including senior management roles with Eli Lilly, Cardinal Health and AGFA Healthcare, Tom Walker will be responsible for the Company’s Business Development Operations, including the design and implementation of all Sales and Marketing strategies. He will lead the Company’s efforts in Strategy and Planning, Product Development, Brand Development and Management and Business Development.

Mr. Walker has demonstrated success in corporate governance, strategic planning, business development, sales and marketing, operational management and the development of strategic and financial partners. He has extensive early-stage experience in medical device and diagnostic Life Science markets, and Mr. Walker has participated in a number of successful medical device company targeted acquisitions including Pyxis Corp. by Cardinal Health, Inc. and Mitra Imaging, Inc. by Agfa.

“I am impressed with T-Ray’s patented imaging and spectroscopy technologies and view this appointment as an opportunity to bring a multi-spectral imaging system for non-invasive, in vivo skin cancer detection to market,” said Mr. Walker. “There is great potential for our device to detect skin cancer at an earlier stage than exists today and therefore positively impact patient outcomes. We offer the potential of an “optical biopsy”, diagnosing skin cancer optically rather than using current surgical methods. This will allow for early and accurate detection while dramatically reducing the need for costly, invasive biopsy procedures.”
