New Features include Advanced Analysis and Calculations Package for Obstetricians, Gynecologists and Fertility SpecialistsUpgrade Available to TITAN Installed Base via CompactFlash CardCustomer Shipments to Begin this WeekPHILADELPHIA, May 3, 2004 - (Nasdaq: SONO), the worldwide leader in high-performance, hand-carried ultrasound, today announced at the 52nd Annual Meeting of the American College of Obstetricians and Gynecologists (ACOG) that it is adding expanded OB/Gyn calculations and measurement capabilities on TITAN, the company's newest generation, hand-carried system. Sonosite will begin shipments of the new capabilities this week and customers can easily upgrade their existing TITAN systems via a CompactFlash card. Sonosite will be introducing these new capabilities in Booth #865 during the ACOG meeting in Philadelphia from May 3 - 5, 2004. "OB/Gyn physicians have been anchor market adopters of Sonosite's technology since we introduced the first hand-carried ultrasound systems," said Kevin M. Goodwin, Sonosite president and CEO. "Their input has been critical as we developed TITAN and this latest upgrade to address their needs for a high-performance system that was robust enough to travel with them from patient to patient." The TITAN system is based on Sonosite's proprietary ASIC (Application Specific Integrated Circuit) technology, which integrates millions of transistors onto one circuit, reducing size while offering excellent image quality and performance. Weighing only 7.7 pounds, TITAN was designed for durability and highly mobile use. The ASIC technology allows for a 12-second boot speed enabling clinicians to immediately deliver patient care efficiently and effectively. "TITAN gives us the flexibility to provide a complete OB exam right in the clinic and the reassurance that we are getting accurate information on fetal growth and overall pregnancy health," said Dexter M. Page, M.D., a perinatologist who has used the TITAN system since its 2003 introduction in his seven-office maternal fetal practice in Atlanta and surrounding area. "It really helps in the labor and delivery setting and is far superior to the systems typically found in these hospital departments." According to industry sources, the OB/Gyn market is the third largest clinical segment of the U.S. ultrasound market, accounting for more than $170 million in revenues in 2003. The majority of the approximate 36,000 OB/Gyn physicians in the United States are in private practice. Industry analysts also estimate that hand-carried ultrasound will account for approximately 30 percent of the OB/Gyn market by 2010 because its performance, size and cost is highly suited to private office practice. The size of the TITAN's system size makes it ideal for practitioners who must move from room to room or from office to hospital. TITAN is a trademark of Sonosite, Inc. About SonositeSonosite, Inc.
