Webimage processing in clinical ultrasound systems for some time, but not for front-end beamforming. However, with a trend towards using more software in ultrasound imaging systems, some attempts have been made to support software-based beamforming using DSPs. Sohn et al. presented a system using 16 ADSP-TS201 DSPs for beamforming [2].
WebWe found it takes 200 μs to beamform 2048 samples from 64 channels using 2 cores. With 4 cores, 20 million samples can be beamformed in one second. Therefore, ADC frequencies up to 40 MHz with 2:1 decimation in AFE chips or up to 20 MHz with no decimation can be supported as long as the ADC-to-DSP I/O requirement can be met. glittering adornment crosswordWebsimulator (SIMUS) for MATLAB, which belongs to the MATLAB ware UltraSound Toolbox (MUST).
