Figure 3

The RANSAC-based iterative removal of outliers as implemented for SWS estimation (Wang et al. 2010) is shown for the two datasets examined in figure 2. A steeper time to peak displacement versus lateral position corresponds to a slower shear wave speed as shown for the figure on the left at 1 mmHg hepatic pressure as compared with the figure on the right at 44 mmHg pressure. Both datasets were collected in the unconstrained case for which the liver was allowed to expand with increased pressure.
