Noninvasive characterization of velocity profiles and shear rates within microcirculation system using a novel micro-ultrasound imaging technique

摘要：

We have recently developed a novel contrast-basedmicro echo particle imaging technique (Micro-EPIV) for non-invasivelymeasuring multi-component flow vectors and flow-inducedshear stress in microscale tube flow or in vivo smallblood flows. In this study, the measuring principle and systemcharacterization are first introduced. Then, the Micro-EPIVtechnique is applied to examine flows in several small tubes ofdifferent geometric shapes, and detailed velocity vector andcontour distribution, and shear distribution are obtained. Theresults are verified by ultrasound Doppler technique andanalytical solutions, and are confirmed by the results fromseveral previous literatures.
