Intraop Receives Two Mobetron Orders from Japan

16th and 17th Mobetron Units Sold Worldwide

SUNNYVALE, Calif.--(HSMN NewsFeed)--May 31, 2006--Intraop Medical Corporation (OTCBB: IOPM ) has received two orders from Japan for its proprietary Mobetron® system, a mobile electron-beam device designed for intraoperative radiation therapy (IORT). The new Mobetrons will be installed at the Gunma Prefectural Cancer Center and Nagoya University Hospital, two treatment locations already actively administering IORT, the direct application of radiation to a tumor while a patient is undergoing cancer surgery. With these two orders, Intraop has sold 17 Mobetron units worldwide, including three in Japan.

"These two orders, our 16th and 17th worldwide, and our second and third in Japan, follow the recent sale of a to Saint Augustinius Hospital in Antwerp, Belgium. We believe this is a result of a successful business development program, which we hope will continue to produce increasing sales," said Dr. Donald A. Goer, President and Chief Executive Officer of Intraop. "We have been working diligently with our partner in Japan, Chiyoda Technol Corporation, to introduce the Mobetron's modern IORT technology to Japan, and we are gratified that these efforts are beginning to bear fruit. The Mobetron allows treatments to be delivered with greater convenience and less cost and disruption, and we believe other hospitals in Japan are likely to follow the example of Nagoya and Gunma."

Gunma Prefectural Cancer Center and Nagoya University Hospital are two of 80 hospitals in Japan with active IORT programs. Although Japan is considered the birthplace of modern IORT, almost all Japanese centers transport the patient, in the midst of surgery, from the operating room (OR) to the radiation department to receive the IORT treatment. The Mobetron, by contrast, is self-shielded and designed for use in the operating room. The Gunma and Nagoya Mobetron units will be the first IORT systems in the country to be located in the OR.

The hospitals intend to focus initially on the use of IORT for pancreatic cancer and early-stage breast cancer. Nagoya has requested delivery of its Mobetron this year. Gunma has asked for delivery of its Mobetron to coincide with the opening of its new cancer center hospital in early 2007.

About Gunma Prefectural Cancer Center and Nagoya University Hospital

With a population of 2,032,709, Gunma, located northwest of Tokyo, is the 19th most populous of Japan's 47 prefectures. Gunma Prefectural Cancer Center is the main cancer treatment center for the prefecture. The Mobetron will be delivered to Gunma in early 2007 to coincide with the completion of its new cancer hospital.

Nagoya, Japan's fourth largest city and the capital of Aichi prefecture, is located southwest of Tokyo. The Mobetron at Nagoya University, one of the major cancer treatment centers in the prefecture, is scheduled to begin clinical treatment before the end of the year.
