The estimated lateral displacement images when the applied lateral displacement is 0.3125 mm and the pitch is (a) 1.25 mm, (b) 0.625 and (c) 0.3125 mm, respectively, and (d) 3-D plot of the estimation jitter varied with the pitch and lateral displacement, (e) the bias and (f) jitter of the estimation and (g) correlation coefficient (average ± SD) as a function of the lateral displacement at different pitch. (beamwidth = 2 mm).
