Fig. 7.

Average estimated displacement (left) and standard deviation (right) for each estimator over 1000 trials when simulated echo shifts are varied between 1 and 3 samples. The dashed line is defined as the ‘true’ displacement, which corresponds to the peak displacement in the beam. The default simulation conditions of Table I were used such that both out-of-beam decorrelation and differential motion decorrelation were simulated.
