November 20, 2013 — Cephasonics introduced the small, 2-pound cQuest Dragonfly family of modular 32- or 64-channel, high-performance ultrasound systems, which, along with the included cQLink network communications technology, it will showcase at Medica 2013 Nov. 20-23 in Dusseldorf, Germany. Cephasonics will be located in the U.S. Pavilion in Hall 16, Booth D18-3. Following Medica, Cephasonics will be exhibiting Dragonfly at the Radiological Society of North America Annual Meeting (RSNA 2013) Dec. 1-6 in Chicago.
 
“The technology is a game-changer in two ways,” said Bern Shen, chief medical officer, HealthCrowd and member of the Cephasonics Medical Advisory Board. “One is the quality of the images and the other is the size and portability.”
 
“Only 5 inches [by] 4 1/2 inches [by] 2 inches in size and weighing just two pounds, Dragonfly is a full-fledged high-performance embedded-ultrasound system," said Richard Tobias, CEO and president, Cephasonics. "Our flexible API software makes it easy for our customers to go into production quickly with a range of ultrasound-based end products with industry-leading size, performance and cost.” 
 
Two typical use cases are small point-of-care appliances for clinical applications and wearable wireless ultrasound devices for both medical and industrial applications.
 
Cephasonics’ new cQuest Dragonfly platform supports up to 192-element probes. The included cQuest Ultrasound API software gives customers an easy, fast way to develop ultrasound-based products from portable standalone imagers to application-specific appliances to adding ultrasound capability to existing equipment in medical and industrial applications. The system hardware transmits and receives analog, digital and power circuitry along with an embedded host MCU. The system design builds upon Cephasonics’ products, including its AutoFocus beamforming technology.
 
Announced earlier in 2013, cQLink client/server technology allows all control and ultrasound data between the server and client sides to take place across a wireless Wi-Fi network or over the Internet. Ultrasound applications developed with cQLink no longer need to run adjacent to the underlying cQuest Ultrasound hardware.  Up to eight displays can be hooked up.
