“…To reduce the computational time required to perform the shear modulus inversion, we further down-sample the number of points in the inversion ROI. The down-sampling rates used for Subject 1 and Subject 2, are [4,4,4] and [3,6,8], respectively, in x , y , z directions. The final mesh for modulus reconstruction contains 41 × 32 × 8 nodes for Subject 1, and 36 × 40 × 8 nodes for Subject 2, in x , y , z directions, respectively.…”
