Background,Motivation and Objective Dynamic contrast-enhanced ultrasound(d-CEUS) imaging enables the estimation of blood perfusion in tissue.However,in many cases respiratory movements add substantial motion artifacts to the scans.Therefore,motion compensation is important for reliable analysis of d-CEUS movies.Although B-mode based image registration can compensate for in-plane movement,frames acquired outside of the main imaging plane should be excluded.Currently due to the incompatibility of standard d-CEUS processing methods with non-uniformly sampled data,study scans containing considerable motion artifacts are discarded.This work aims to facilitate the estimation of perfusion parameters and visualization of vasculature even when a significant percentage of frames are excluded.
