Arrival time vs. position for shear wave propagation across the (a) 10 mm vertical layer and (b) spherical inclusion determined using the Xcorr50, Xcorr100, TTP, and TTPS methods. The boundaries of the layer and spherical inclusion are indicated by the dashed lines at positions of 10 and 20 mm. Arrival times determined using the TTP and TTPS methods are absolute. Arrival times determined using the Xcorr50 and Xcorr100 methods are relative, and these curves have been shifted for clarity.
