摘要
利用常规的多普勒系统较难进行低速血流的测量,本文在讨论了常规的多普勒系统的局限后,就一种可测量低速血流的超声多普勒技术的原理、方法进行讨论,并通过计算机模拟实验实现了这种方法。
It is difficult to measure the low blood flow velocity using a conventional Doppler system. After discussion of the limits of conventional Doppler systems, a method based on Doppler ultrasound technique is proposed to measure the low blood flow velocity. Computer simulation for this method is also given in this paper.
