Background, Motivation and Objective Pulse wave imaging (PWI) is a noninvasive technique developed by our group for tracking the propagation of pulse waves along the arterial wall at high spatial and temporal resolution. In order to achieve high frame-rates without relying on stroboscopic techniques (ECG-gating), plane wave acquisitions were implemented. However, single planewave transmission results to lower SNR and higher side-lobe levels that further challenge the motion estimation techniques. Coherent compounding is known to significantly improve displacement estimation at the cost of lower frame-rate.
