Abstract:Hemodynamic quantities like wall shear stress (WSS) and blood pressure in the carotid arteries have been found to correlate with plaque development and arterial remodelling which could result in atherosclerosis, which is one of the leading causes for ischemic strokes. Computational fluid dynamics (CFD) is a tool that can be used to simulate blood flow inside arteries and from there these hemodynamic quantities can be calculated. In this work, data generated from applying a segmentation algorithm on MRI-scans of carotid arteries in a patient is used to construct a 3D tetrahedral finite element mesh of the lumen wall of the artery. The incompressible Navier Stokes equations are solved inside the mesh to get a steady state velocity and pressure profile over the artery. Using this flow profile, clinically relevant biomarkers can be found. This research therefore provides a general way of finding blood flow inside MRI-derived carotid artery segmentations.
