Abstract Frame rate is an important metric for ultrasound imaging systems, and high
frame rates (HFR) benefit moving-target imaging. One common way to obtain HFR
imaging is to transmit a plane wave. Delay-and-sum (DAS) beamformer is a conventional
beamforming algorithm, which is simple and has been widely implemented in clinical
application. Fourier beamforming is an alternative method for HFR imaging and has high
levels of imaging efficiency, imaging speed, and good temporal dynamic characteristics.
Nevertheless, the resolution and contrast performance of HFR imaging based on DAS or
Fourier beamforming are insufficient due to the single plane wave transmission. To
address this… More >
