A computational fluid dynamics approach is presented to simulate the blood flow in the human cerebral arteries including the peripheral vessels. The difficulty to determine the boundary conditions at the truncated position is overcome by using modeled peripheral vessels. The method is applied to the simulation of realistic 3-D Circle of Willis model that is reconstructed from a computed tomography image. Results of the simulation such as prescribed outlet pressure of 3-D model and the number of bifurcations are compared with some empirical data and have turned out to be in reasonable agreement between both of them.
