Background, Motivation and Objective Multi-angle plane-wave imaging provides new opportunities for high frame rate vector-Doppler imaging, as well as improved low flow imaging by providing longer temporal ensembles and the possibility of coherent compounding. However, to achieve robust vector-Doppler estimates and a significant effect of the coherent compounding process a high number of angled plane waves is desired. This comes at the expense of aliasing in vector-Doppler (lowered PRF) and motion artifacts (SNR loss, blood velocity bias) in the compounding process (Ekroll et al., "On the accuracy of coherent compounding in Doppler imaging", Proc. IUS, 2014).
