This paper aims to visualize and measure flow structure in the cerebral aneurysm model, which is based on the medical image data. Since a blood vessel has bend and bifurcation with pulsatile blood flow, the flow structure becomes complex in the three-dimensions. The stereo PIV technique is applied to measure and visualize the flow. We calculate the wall shear stress using measurement data and the geometry data of lost model, which is used to make cerebral aneurysm model. As results of measurement at the peak systole in the pulsatile inflow condition, the flow runs into the tip of the aneurysm. The wall shear stress of the region of the aneurysm is lower than that of the region of the vessel.
