A PSF-Shape-Based Beamforming Strategy for Robust 2D Motion Estimation in Ultrafast Data

This paper presents a framework for motion estimation in ultrafast ultrasound data. It describes a novel approach for determining the sampling grid for ultrafast data based on the system’s point-spread-function (PSF). As a consequence, the cross-correlation functions (CCF) used in the speckle tracki...
