摘要：

Slow blood flow ultrasound imaging is challenging because of tissue clutter interference. We previously introduced an adaptive demodulation (AD) technique to address this that was developed and validated using unfocused single plane wave (SPW) power Doppler imaging. Other beamforming methods have been proposed to improve slow flow ultrasound imaging, including plane wave synthetic focusing (PWSF) and coherent flow power Doppler (CFPD). The benefits of these alternative beamforming methods are evaluated here using simulations and perfusion-mimicking phantom data. AD+CFPD resulted in the highest simulated blood-to-background SNR of 10.1dB. Qualitatively, AD improved clutter suppression and slow flow visualization for all three beamforming cases in the perfusion-mimicking phantom experiment.
