Abstract
The aim of this work is the development of a three-dimensional (3D) PW Doppler system capable of measuring the velocity vector field (module and direction) without correction for the probe-to-flow angle. The applications of this instrument are in the field medical imaging of blood flow, and for industrial applications. The 3D PW Doppler method was studied theoretically by the authors1 and it can be used for volumetric scans of flow and quantitative estimation of the velocity vector field in the region of interest. In medical applications where the determination of the probe-to-flow angle is often inaccurate, this technique allows to eliminate the uncertainty due to the angle correction.
