Cephasonics Releases New cQuest Dragonfly Family of Ultra-Compact Ultrasound Systems

SANTA CLARA, Calif., Nov. 18, 2013 /PRNewswire/ -- Cephasonics, a technology-innovation leader with a game-changing embedded-ultrasound platform, today announced the introduction of the cQuest Dragonfly™ family of modular 32- or 64-channel, high performance systems engineered for size and flexibility. Dragonfly, along with the included cQLink™ network-communications technology, will be showcased at Medica 2013 held in Dusseldorf, Germany from November 20-23.  Cephasonics is located in the U.S. Pavilion in Hall 16, Booth D18-3. Following Medica, Cephasonics will be exhibiting Dragonfly at RSNA 2013 in Chicago from December 1-6.

According to Dr. Bern Shen, chief medical officer of HealthCrowd and a member of the Cephasonics Medical Advisory Board, "the technology is a game-changer in two ways.  One is the quality of the images and the other is the size and portability."

"Our cQuest Dragonfly systems are optimized for next-generation, go-to-market ultrasound products," said Richard Tobias, CEO and president of Cephasonics. "Only 5 inches x 4½ inches x 2 inches in size and weighing just 2 pounds, Dragonfly is a full-fledged high-performance embedded-ultrasound system. 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 is a product family of ultra-compact, complete 32- or 64-channel embedded-ultrasound systems that support 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 includes all the ultrasound-specific front-end transmit and receive analog, digital and power circuitry along with an embedded host MCU. The system design builds upon Cephasonics' award-winning technology, including its AutoFocus™ beamforming technology.

Announced earlier this year, 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.
