SonoSite Begins Customer Shipments Of M-Turbo System

Company Begins Delivery of Fourth Generation Hand-Carried Ultrasound System Johns Hopkins Bayview Emergency Department Among the First

BOTHELL, WA, December 5, 2007 - SonoSite, Inc. (Nasdaq:SONO), the world leader in point-of-care, hand-carried ultrasound, today announced that it has begun worldwide shipments of the M-Turbo™ ultrasound system, its fourth generation product. The M-Turbo system packs 16-times more processing power than SonoSite's industry-leading MicroMaxx® system, delivering breakthrough image clarity across all exam types and seamless connectivity for digital image export in a rugged, hand-carried product weighing less than 8 pounds.

"The M-Turbo has it all," said William T. Hosek, MD, MBA, Director of Emergency Medicine Focused Ultrasound and Assistant Professor at Johns Hopkins Bayview Medical Center, Baltimore who is receiving the first hospital shipment. "I have been waiting a long time for a system with superior image quality, quick boot-up time and easy data transfer.

The M-Turbo system also has an extremely intuitive design, which gives the novice the ability to easily master the controls after just a brief time. While larger machines may provide good images, their long boot-up time and lack of maneuverability are a disincentive for use in a quick paced, busy ED. With the M-Turbo, by the time you get the gel on the probe, you€™re ready to roll." SonoSite has been demonstrating its M-Turbo system alongside SonoSite€™s radically new S Series„¢ ultrasound tools at leading clinical meetings in the US, Europe and Australasia in emergency medicine, anesthesia and critical care.

Customer deliveries of the S Series products are scheduled to begin later this month. "With the introduction of the M-Turbo system, we have again executed an on-time launch and delivery schedule for a completely new product platform, and strengthened our long-standing leadership position in the hand-carried ultrasound industry," said Kevin M. Goodwin, SonoSite President and CEO. "While still early, we have received very enthusiastic feedback from physicians who have evaluated the product, and it is our expectation that our fourth generation products will quickly become the standard for image quality, user simplicity and speed in point-of-care clinical settings."
