Medical IMAGE-Based Numerical Simulation of the Abdominal Aorta Flow

Blood hemodynamics have a crucial role in the treatment of the cardiovascular disease. In this paper, the 3D model segmentation was based on Computed Tomography Angiography (CTA) reconstructed images with pixel spacing 0.703125/0.703125 and slice thickness 1.25 mm. The reconstructed abdominal aorta's geometry was meshed and numerically investigated separately in SimVascular and Ansys tools. It is important to mention that both numerical simulations predict the complexity of the, namely flow separation (acceleration and recovery area) that induce low and high WSS regions and enhanced particle residence time near to the artery wall. Practically, both solvers used in this paper increase researchers' effort in the cardiovascular system's fundamental understanding.
