August 17, 2006

Independent survey shows majority of customers report image quality is better than other ultrasound products used BOTHELL, WA - August 17, 2006 - SonoSite, Inc. (Nasdaq:SONO), the world leader in hand-carried ultrasound, said today that an independently conducted, random survey of U.S. SonoSite customers showed that 97% are highly satisfied overall with their system with nearly 9 out of 10 customers saying in the statistically significant survey that they are "completely" or "very satisfied". Respondents were required to be involved in the day-to-day operation or usage of the SonoSite products being profiled and not just involved with the acquisition decision. Image quality, ease of use, system reliability and durability, and ergonomic design of transducers were key reasons for the high satisfaction rating.

Two-thirds of respondents said that image quality of their SonoSite product is better in comparison to other ultrasound products they have used. Over 60% of the survey participants owned MicroMaxx systems, approximately one-third owned TITAN systems and the remainder profiled were 180PLUS users. Over 90% of respondents were physicians and the majority of respondents were hospital based.

"This is the third independent survey that we have commissioned over the last 18 months that confirms our products are meeting or exceeding customer expectations by an extraordinarily high margin," said Kevin M. Goodwin, SonoSite President and CEO. "As the innovator and specialist in hand-carried ultrasound, we design our products to enable physicians to deliver better care to their patients while increasing productivity and streamlining workflow." Verispan, an independent health care information research firm, conducted the company-commissioned survey.
