Abstract
It is assumed that cerebral homodynamics is an important factor for the cerebrovascular disorders such as subarachnoid hemorrhage. Since a blood vessel has bend and bifurcation, the flow structure is in the three-dimensions. The Stereo PIV is a suitable method for measurement of complicated flow phenomena. The Stereo PIV uses a plate in a measurement domain for calibration. However, if the domain is complicated, it is difficult to place such an object. In this research, we have presented a noninvasive calibration method using a calibration point created by laser beams.
