BAT(R) SXi Image-Guided Radiation Therapy Equipment Approved for Sale in China

CHATSWORTH, Calif.--(HSMN NewsFeed)--Feb. 21, 2006--North American Scientific, Inc. (Nasdaq:NASI ) today announced that its NOMOS® Radiation Oncology Division (NOMOS) has received regulatory approval from the People's Republic of China State Food and Drug Administration (SFDA) to sell its BAT SXi, an ultrasound-based localization system used to view cancerous tumors prior to the delivery of radiation therapy. The image-guided radiation therapy (IGRT) system is designed to be compatible with all linear accelerators and most treatment planning systems. The SFDA approval clears the way for North American Scientific to immediately begin selling BAT SXi in China.

"We have continued to make progress on our strategy to bring our full range of products to China and the SFDA's approval of BAT SXi is an important indicator of our success," said L. Michael Cutrer, President and Chief Executive Officer of North American Scientific, Inc. "Our BAT SXi system provides proven ultrasound technology to view and target tumors prior to radiation therapy treatments making it an affordable and highly effective tool to deliver comprehensive patient care.

"We received approval for our PEACOCK® intensity-modulated radiation therapy (IMRT) product in September 2005 and announced our first significant sale in January 2006," continued Mr. Cutrer. "We believe that our products and services can meet the existing and unmet needs of healthcare providers focusing on cancer treatment. We also believe that China provides a substantial opportunity for us to expand our international presence. These approvals are two important milestones for our expansion strategy and we remain hopeful that we will have our full range of products available in China during fiscal 2006."

North American Scientific is also in the process of registering in China its Prospera® I-125 brachytherapy seeds for the treatment of prostate cancer.

About BAT

NOMOS's launch of BAT in 1998 introduced physicians and clinicians in radiation therapy departments and clinics throughout the world to a revolutionary ancillary treatment device. BAT (B-mode Acquisition and Targeting) is an image-guided radiation therapy (IGRT) targeting system that provides fast ultrasound localization of a treatment target on a daily basis. BAT combines ultrasound and a 3D tracking system with a touchscreen-based treatment room interface to non-invasively pinpoint tumor targets rapidly and accurately at the time of a radiation therapy treatment. It dramatically reduces the need for large target margins which have traditionally been used to compensate for errors in localization.

BAT is compatible with all treatment planning systems, from conventional 3D to precision IMRT, and is currently used in conjunction with IMRT and conventional therapies to treat prostate, breast, pancreas and liver cancers.

Today, BAT is in its fourth generation of hardware - BAT Classic, BAT SXi with articulated arm, BAT SXi with optical camera, and today's BATCAM(TM) - and five generations of software that include breakthrough ImageSync(TM).
