A Fully Automated Ultrasound Imaging Pipeline for 4D Intraventricular Flow Reconstruction - in Vivo Comparison to Phase-Contrast MRI

Ultrasound vector flow imaging (VFI) has shown potential for measuring intraventricular flow patterns, which may reveal clinical information not currently exploited. Current methods are hampered by measurement noise and dropouts which limits its applicability. We previously introduced a regularization approach to reconstruct 4D flow velocity fields based on VFI, validated in silico and in vitro. We here introduce a fully automatic pipeline, and compare results in vivo towards phase-contrast MRI.
