From: Enhanced ultrasound particle image velocimetry (E-uPIV) enables fast flow mapping of microvasculature

Fig. 3

a Maximum intensity projection (MIP) of acquired contrast-enhanced ultrasound images, depicting the flow channel phantom’s structure and position. Velocity measurements obtained under multiple flow rate conditions are shown for b ultrasound localization microscopy (ULM) and d enhanced ultrasound particle image velocimetry (E-uPIV). c The measured velocities (mean ± SD, N = 3 trials) are plotted as a function of channel flow rate for E-uPIV (green), ULM (yellow), and ground truth (blue), with error bars representing standard deviation.
