Abstract

Accuracies of ultrasonic methods for estimation of motion/deformation should be evaluated, but such evaluation in real experiments is not easy because it is difficult to know the true distribution of motion/deformation in complex geometry, such as an atherosclerotic plaque model. In the present study, numerical simulation was performed to obtain ultrasonic echo signals from a deforming plaque model. The accuracies of our phase-sensitive 2D motion estimator in estimation of velocity and strain rate were evaluated to be 22.8% and 27.6%, respectively, and the spatial features of the estimated velocity and strain rate distributions were well corresponded to the true distributions.
