The aim of this study was to perform automatic coronary artery centerline tracking on coronary MRI data, in a clinically relevant population. Our method consisted of computation of a vesselness filter followed by fast marching. Parameters were optimized on three subjects, and performance was evaluated on 27 other subjects. Centrelines were traced between a start and end point, and when needed with one additional point in between. Tracking was successful in 92% (RCA), 88% (LAD) and 65% (LCX), with a median distance from manual annotation of 1.0mm. These results show that automatic centerline tracking on coronary MRI data is possible.
