  • Abstract
    This paper describes a method for estimating small displacements in ultrasound images. The method is based on the addition of a ldquopseudo-phaserdquo to the intensity ultrasound images and subsequent calculation of the cross-correlation. The peak of the cross-correlation function is interpolated to add precision to the estimates.
