(2007). Observation of blood flow in microchannel with stenosis by confocal micro-PIV. In 3rd Asian Pacific Conference on Biomechanics. Tokyo, Japan.http://hdl.handle.net/10198/1659Mass transport in human cardiovascular system takes place mainly in microcirculation, so it is important to understand blood flow in microvessels. In such small microchannels, behaviors of red blood cells(RBCs) strongly affect the now field. Recently many researcher developed various systems to visualize blood !low in microchannels. But it is very difficult to visualize the center plane or the blood flow when the concentration of RBCs(HCT) is over 10%. In our study, we used confocal-micro-PIV and PTV systems to overcome this problem, and investigate blood flow through stenosis.engRed blood cellMicrocirculationconference object
