Highlights
• Software-based ultrasound system that performs high quality imaging for a fraction of the cost of conventional systems permits implementation of new imaging modes that are not currently feasible on other platforms.
• Prototype custom processing algorithms at any point in the signal chain, from reconstruction through the pixel color map and audio stream, using the Verasonics real-time hooks into standard MATLAB functions.
• Utilize the native Verasonics delay-and-sum reconstruction engine, color processing, and spectral Doppler processing suites as needed, or replace each with your own novel algorithms.
• Provides an environment for the R&D of new ultrasound imaging approaches/modalities (by providing user control of transmit and receive acquisition parameters and all subsequent data processing, including beamforming)
• Provides high power transmit modes with extended burst lengths, suitable for radiation force imaging and moderate HIFU delivery
