Multidimensional SWEI algorithms in rotationally sampled media: Assessing the accuracy of phase velocity reconstruction in transversely isotropic media

In this work we propose and validate an algorithm to estimate phase velocity in anisotropic media using 3D rotational shear wave elasticity imaging. We propose a novel spatial and temporal weighting scheme to achieve millimeter-scale spatial and millisecond scale temporal resolution and apply it to the Eikonal wave equation. We demonstrate the accuracy of the algorithm in simulated and experimental datasets in hyper-elastic materials.
