摘要
本文报道了心动周期内超声多普勒音频信号的分维值计算方法和对超声多普勒信号的分维特征进行统计分析的结果。通过对１００ 多例胎儿脐血流信号的分析研究，结果表明：分维值对某些病症具有敏感性。
Fractal characterization of Doppler Utrasound signals in single cycle, including alogithm and statistic analysis of fractal dimension were studied from more than one hundred samples of umbilical blood flow. The results showed that fractal dimension was more sensitive than sonogram indices.
