INTRAOP MEDICAL ANNOUNCES RECORD SALES, EXPANSION INTO NEW MARKETS AND DEVELOPMENT OF SALES ORGANIZATION

2006 marks record sales for IntraOp as the medical community further embraces intraoperative electron-beam radiation therapy (IOERT) for the treatment of cancer

IntraOp Medical Corporation (OTCBB: IOPM), announced today the company achieved record sales in 2006 and is poised for continued growth and success in 2007 with the development of its sales infrastructure, expansion of its distributor relationships and rise in interest in intraoperative electron-beam radiation therapy among cancer treatment professionals.

In 2006, IntraOp sold five and accepted orders for eight Mobetron self-shielding linear accelerators for administering electron-beam radiation therapy during cancer surgery. The company accepted orders from U.S. cancer centers as well as Belgium, Poland, China, Italy, Japan and the Netherlands. To date, the Mobetron is being used in seven countries and has helped invigorate interest in IOERT for the treatment of a broad spectrum of cancers in various stages of severity. Last year, a number of critical studies were published illustrating the effectiveness of IOERT from the The European Institute of Oncology (EIO), Catharina Hospital, in Eindhoven, The Netherlands, University of Heidelberg, Germany, and the Catholic University in Rome, Italy.

IntraOp has doubled its production capacity, added a distributor in Scandinavia, Admedico, and opened a sales office in Cologne, Germany, to meet the demand for Mobetrons. In addition, IntraOp added three seasoned medical-equipment salespeople in the U.S. and one in Europe:

M. Dean Whitney, Eastern Region Sales Manager

Thomas C. Rhea, Central Region Sales Manager

Charles E. Medalie, Western Region Sales Manager

Stefan Dirks, Director of Sales, Northern Europe

All four salespeople each have more than 25 years experience in medical imaging and radiation oncology equipment sales with companies such as Varian, Nucletron, Impac, Siemens and Nomos.

The company has also increased its activity in professional forums to raise awareness for and educate doctors, radiation oncologists, surgical oncologists and hospital administrators to the medical, monetary and marketing benefits that IOERT devices can bring to cancer treatment centers and their patients.

IntraOp met with more than 130 of the nation's leading radiation oncologists and international delegates at the American Society for Therapeutic Radiology and Oncology (ASTRO) Annual Meeting in November 2006 in Philadelphia, PA. More than 100 surgical oncologists attended the International Society of Intraoperative Radiation Therapy's (ISIORT) special session disclosing clinical research results at the European Society of Surgical Oncology's (ESSO) 13th Congress in Venice, Italy, in the same month. At both events, IntraOp met with prominent researchers and medical practitioners that are fighting cancer on a daily basis with their patients. Italy in particular is at the forefront of IOERT usage. There are currently 18 hospitals in Italy using some form of intraoperative radiation therapy - three are using the Mobetron.

"In 2006 we laid the foundation for strong growth for IntraOp," said Donald A. Goer, president and CEO of IntraOp Medical Corporation. "The infrastructure that we put into place - doubling our production capacity, expanding our sales team, investing in public relations and marketing - is designed to enable us to take advantage of the growing interest in and demand for IOERT solutions. The Mobetron is fundamentally changing the way cancer patients are being treated today and positively impacting their survival."
