Simulation results over 1000 trials when maximum displacement per ensemble is varied from 0.25 samples to 7.0 samples. Plots display (a) RMS error, (b) standard deviation at acquisition 400 and (c) average decorrelation between consecutive echoes (average N to Nāˆ’1 decorrelation). Results are shown for the bandpass (BP) filter and complex PCF. The RF filtering methods were used in conjunction with either the N to Nāˆ’1 or N to 1 delay profile estimation technique.
