Abstract

The invention relates to processing multiple cardiac images depicting a portion of coronary arteries within an anatomical region of interest. A respective set of lumen radius measurements is determined based on each of the multiple cardiac images and comprises multiple lumen radius measurements respectively associated with multiple locations of the portion of the coronary arteries. One or more locations of the multiple locations, at each of which at least two sets of the respective sets of lumen radius measurements all have a local or relative extremum, e.g., either a local maximum or a local minimum, are determined based on the respective sets of lumen radius measurements. Rigid-motion artifacts in the multiple cardiac images are corrected based on the one or more locations.
