Figure 5From: A regularization-free elasticity reconstruction method for ultrasound elastography with freehand scan The estimated Young’s modulus distributions. (a) The theoretical Young’s modulus distribution. (b) The Young’s modulus reconstructed from the theoretical displacements calculated from finite element analysis. (c) The Young’s modulus reconstructed from the estimated displacements from optical flow. (d) The Young’s modulus reconstructed from the estimated displacements of B-spline fitting.Back to article page
