The Image-Based Simulation is a promising method to examine blood flow in the artery for investigation of the relationship between cardiovascular diseases or cerebrovascular disorders and hemodynamics. In general, the image-based simulation is performed for a particular region where the disease tends to occur so as to obtain solutions within reasonable computational time. The authors have been engaged in the image-based simulation for blood flow in the cerebral arties and aneurysms in order to understand the mechanism of creation, growth, and rupture of aneurysm. Thus, it is important to include the influence of entire vascular network system over the designated region. In order to achieve this purpose, the paper develops the boundary condition model based on the anatomical geometry of cereborvascular geometry. The simulation was conducted to examine the applicability of the present method.
