Finite element simulation of blood flow in the cerebral artery. (English) Zbl 0999.76081
Summary: We develop a numerical simulation system for the clinical study of a cerebral aneurysm. This paper presents the system which consists of three processes: pre-processing, numerical simulation, and post-processing. In the pre-processing process, the three-dimensional solid model is constructed from the computed tomography angiography raw data. The finite element method is used in order to simulate flow in a complicated geometry. The simulation is conducted to investigate hemodynamics of blood flow in the carotid siphon under real flow conditions measured by Doppler ultrasound velocimetry technique. The results are visualized for a better understanding of flow characteristics, such as distributions of flow patterns and the wall shear stress in the carotid siphon.
