Computational simulation of circulatory system is being used to aid the diagnosis of certain blood vessel diseases, such as stenosis or aneurysm. As the calculation time and accuration is the main issue, selecting the appropriate computational methods and constructing overall system. Windkessel model is selected as the boundary system for the diagnosis of cardiac artery system, as it provides fair accuracy and calculation time. However, for the case of fermoral artery stenosis, this model is insufficient to properly apply the vessel stiffness which is one of the critical variable in diagnosis of femoral stenosis. To overcome this problem, this paper introduces the impedance boundary condition. Impedance boundary condition can successfully apply the downstream vessel by 1D model and therefore consider the stiffness and other vessel conditions. When used in diagnosis of femoral artery stenosis, the accuracy can increase greatly with maintaining the short computational time.
