我们以无创方式观察颈总动脉的弹性。弹性指数是根据动脉扩张速度和连续血压计算得出的。扩张速度是通过处理高帧率回波描记术记录的时间序列回波图给出的。使用缠绕在手臂上的袖带，通过无创血压计测量血压。速度的转变与血压有关。绘制压力-速度曲线，可以根据曲线的形状对颈动脉的弹性进行分类。在年轻的弹性动脉中，显示的曲线类似于圆形。相对于较老的动脉，曲线的形状变得平坦。从曲线的封闭面积可以估计动脉的弹性。
We visualized elasticity of the common carotid artery noninvasively. The elastic index is calculated from an expanding velocity of artery and continuous blood pressure. The expanding velocity is given from processing time series echograms recorded by high-frame-rate echography. Blood pressure is given from a noninvasive sphygmomanometer using a cuff wound up to arm. The transition of velocity is related to blood pressure. Drawing a pressure-velocity curve, elasticity of the carotid artery can be classified from the shape of the curve. In a young elastic artery, the curve revealed is similar to a circle. In relation to an older artery, the shape of the curve becomes flattened out. From the enclosed area of the curve, the elasticity of the artery can be estimated.
