Abstract

Motivation of the project is the analysis of systematic errors in contrast-enhanced cardiac perfusion imaging by CFD simulations of contrast agent transport in the arterial epicardial vasculature. This requires the realistic modeling of volume blood flow (VBF) in the coronary arteries to provide a physiologically relevant computational framework for the transport simulations. For this purpose, 3D-models of the left and right coronary trees are extracted from high-resolution cardiovascular cryomicrotome imaging data and meshed with computational grids. A dedicated model integrating characteristics of coronary blood flow is used to generate boundary conditions (BCs). Subsequently, VBF is analyzed in left and right ventricular myocardial regions (VBF m ) and in dependence of the vessel sizes (VBF v ). Regarding the distribution of VBF m in the myocardial segments, good agreement with literature values is found. Partial compliance of the findings of the VBF v -analysis with results from other groups is promising, however, indicates room for improvement.
