(a) Unfiltered and (b) Directionally-filtered median shear wave speed map across all 64 voxels at 4 cm depth in the boundary phantom. The contributions of each tracking voxel were limited to push-track separation distances between 4 and 19 mm. The boundary is clearly visible at x = −5 mm, with reflection artifacts enhancing boundary contrast in (a).
