Comparison of best motion filters. Results from both canine subjects are shown above. 0:4 and 1:4 are temporal interpolation filters applied in previous studies using zero prereference tracks and four postrecovery tracks (3.0 to 3.3 ms) and one prereference track (−0.1 ms) and four postrecovery tracks (3.0 to 3.3 ms) respectively. The interpolation filter uses two prereference tracks (−0.2 ms, −0.1 ms) and one postrecovery track (3.0 ms). The extrapolation uses four prereference tracks (−0.4 to −0.1 ms). The weighted filter uses five prereference tracks (−0.5 to −0.1 ms) weighted 1 and seven tracks from 0.4 to 1.0 ms after the simulated ARFI push weighted 0.001, 0.005, 0.01, 0.05, 0.1,0.5 and 1. The close time interpolation filter use two prereference tracks (−0.2 ms, −0.1 ms) and two post-reference tracks (1.0 ms, 1.1 ms).
