Abstract

Computational fluid dynamics (CFD) studies play an important role in the analysis and prediction of atherosclerosis in coronary arteries. Haemodynamics, in particular endothelial shear stress (ESS), is believed to influence the unhealthy development of the endothelium. In this study, we compared the geometric variances of a patient-specific arterial segment using multiple medical imaging modalities and their effects on haemodynamics. Three-dimensional patient coronary artery reconstructions using standalone X-ray angiography are able to only approximate the artery cross-section as ellipses. On the other hand, intravascular optical coherence tomography (OCT) provides high resolution cross-sec..
