Frequency-domain high frame-rate 2D vector flow imaging

Résumé

Background, Motivation and Objective Conventional ultrasound flow imaging systems are limited to estimate only the axial component of blood velocity. In this paper, a new method to produce 2D vector Doppler maps is proposed and experimentally tested. Differently from cross correlation based methods, local displacements between consecutive high frame rate (HFR) images are estimated in the frequency domain, extending a 1D displacement estimation algorithm so far proposed for elastography applications
