✦ Synopsis

The purpose of the paper is to 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 was constructed from the computed tomography (CT) angiography raw data. The ®nite element method (FEM) is used in order to simulate ¯ow in a complicated geometry. The simulation is conducted to investigate hemodynamics of blood ¯ow in the carotid siphon under real ¯ow conditions measured by Doppler ultrasound velocimetry technique. The results are visualized for a better understanding of the ¯ow characteristics such as distributions of the ¯ow pattern and the wall shear stress in the carotid siphon.
