本文首先介绍＂绝对差值平均算法＂进行超声多普勒胎心率检测的原理和方法，然后通过实验指出＂绝对差值平均算法＂检测超声多普勒胎心率时具有精度高、计算量少的优点，最后给出了实现这种方法的超声多普勒胎心率仪的系统结构。
This paper first introduces the principle and method of “absolute difference average algorithm” for ultrasonic Doppler fetal heart rate detection, and then pointed out through the experiment that “absolute difference average algorithm” has high accuracy and computational power when detecting ultrasound Doppler fetal heart rate. With few advantages, the system structure of the ultrasonic Doppler fetal heart rate meter that realizes this method is finally given.
