An apparatus and method for the determination of the flow, the coronary reserve and relative coronary reserve of a specific coronary artery. The apparatus and method employ a three-dimensional model ( 50 ) providing the volume of a segment of the artery at a plurality of points in time, and disclose various options ( 56 ) for determining the arterial flow through the artery segment during one or more heart beat cycles or parts thereof. The determination of the coronary reserve ( 62 ) and relative coronary reserve ( 64 ) follow from the volume ( 54 ) and the flow through the artery. Alternatively, the coronary reserve is determined directly from a velocity profile relating to one or more fixed artery segments and the three-dimensional model. |
