摘要
报道了一种超声多普勒血流速度定量测量的方法．叙述了任意位置精确测量血流速度的原理，以及反映血管走向夹角的计算方法．提出了按实际情况进行再校正以进一步提高测量流速精度的方法．给出了验证实验的结果，及该方法与准补偿法的比较．
A new method for quantitative measurement of blood flow velocity with Doppler ultrasound is presented. The principle of the precise velocity measurement at any angle and the method of calculation of the angle are described. The re-correction based on the practice is applied to improve the precision of the velocity measurement. Experimental results and comparisons of the method with the quasi-compensation are also given too.
