Samplify Announces New Ultrasound Beamformer Technology

Samplify Systems Inc.'s AutoFocus beamforming technology is optimized for high-performance, low-power ultrasound machines. Autofocus beamforming provides the flexibility for ultrasound OEMs to implement customized and differentiated algorithms that simplify software and system design and speed time to market across a wide range of systems from ultra-low power hand-held machines, through laptop hand- carried machines and low-mid range carts.

"With our AutoFocus beamforming technology, powerful phased array beamforming techniques are now available to classes of machines that could only implement simple algorithms due to power or cost constraints," says Al Wegener, Founder, Chairman and CTO of Samplify Systems. "By leveraging this highly configurable beamforming platform, OEM customers gain the best of both worlds: the lower power and cost benefits of ASIC implementation, and the ability to maintain product differentiation."

Samplify's beamformer technology includes a unique integrated AutoFocus engine which automatically refocuses the receiver to capture reflections at different scan depths. AutoFocus alleviates the real-time requirement of calculating and downloading the delay and weighting coefficients in the back-end computer, thus simplifying software and system design. Four scan-lines are formed simultaneously using QuadBeam 'phased array technology for higher frame rates and improved lateral resolution. All transducer geometry definitions and scan-line parameters are driven from programmable tables, further removing the real-time nature of back-end computer updates while providing beamformer implementation flexibility to the OEM customer. Silicon implementation of the new beamformer will consume up to 90 percent less power versus an FPGA while providing high-end FPGA performance at more cost effective FPGA prices.
