A good knowledge of arterial flow mechanics and of the phenomena associated with fluid-boundary interactions is necessary for the determination of some fundamental parameters such as velocity, pressure and pressure-diameter relationship during a cardiac cycle. Ultrasonic techniques were developed on a test bench and directly applied to animals without major modification. On such a test bench allowing a good simulation of physiological type flows, velocity field and pressure-diameter relationship were determined. In vivo application of these techniques allowed a systematic analysis of velocity profiles in the rabbit abdominal aorta and a precise approach of rheological properties of the vascular wall.
要确定一些基本参数，如心动周期中的速度、压力和压力-直径关系，就必须深入了解动脉血流动力学以及与流体-边界相互作用相关的现象。超声技术在实验台上开发出来后，未经重大修改就直接应用于动物。在这样一个能够很好模拟生理类型血流的实验台上，测定了速度场和压力-直径关系。这些技术的体内应用使得能够系统分析兔腹主动脉中的速度剖面，并精确研究血管壁的流变特性。
