Abstract:
1. A device for determining and visualizing perfusion of a myocardial muscle with aid of non-dynamic computed tomographic angiography, comprising: a segmentation unit to segment coronary blood vessels and a left myocardial muscle from a CT image of a heart; a first simulation unit to simulate a blood flow through the coronary blood vessels on the basis of the segmented coronary blood vessels and to determine from the first simulation, blood flow into different regions of the myocardial muscle into which different branches of the coronary blood vessels lead; a second simulation unit, by which a local perfusion of the myocardial muscle for the different regions is simulated on the basis of the determined blood flow into the different regions of the myocardial muscle and of the segmented left myocardial muscle; and a visualization unit, by which an image of the myocardial muscle is visualized from which the perfusion of the different regions of the myocardial muscle is identifiable.
