The recently developed MATCH technique integrates multiple 3D image sets into a single measurement and it is a promising method for carotid plaque characterization. One of the remaining challenges is the gross motion of carotid arteries that originates from pulsation, breathing and swallowing. In this work, a motion robust stack-of-stars sampling trajectory was implemented into the MATCH sequence (STAR-MATCH). Preliminary studies from volunteers and patient demonstrate it is feasible to characterize carotid plaque using the STAR-MATCH sequence with improve motion robustness.
