Ratios of shear wave speed (SWS) and Acoustic Radiation Force Impulse (ARFI) displacement magnitude measurements inside the sclerotic and contralateral healthy skin. SWS ratio using measured SWS is shown in the left plot (corresponding to data shown in Figure 7) and SWS ratio using skin thickness normalized SWS is shown in the right plot (corresponding to data shown in Figure 8). Median and interquartile range (IQR) of these ratios was (2.28, 0.60), (0.34, 0.19), (1.92, 0.68), (0.34, 0.19) from left to right for SWS, ARFI displacement, SWS, and ARFI displacement respectively.
