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.
