Figure 6

Motion tracking quality versus applied strain for four different experiments, a) spherical inclusion phantom, b) spherical inclusion phantom simulation, c) uniform phantom, and d) uniform simulation. Different quality metrics are applied to the appropriate experiment. a) Mean absolute RF phantom image RF difference (MARD) versus regularization method (lower is better). b) Mean absolute displacement difference (MADD) between the simulated and estimated displacements (lower is better). c) and d) are the mean strain over the standard deviation of the strain (higher is better).
