摘　　要：本文介绍一种多普勒超声心动图血流频谱自动分析系统。该系统由微机及数字图象处理器组成。系统采用基于频谱灰度变化和灰度梯度的算法自动识别和提取多普勒血流频谱的轮廓,使自动分析结果的可重复性和准确性显著地优于人工分析方法。A new processing system composed of microcomputer and image processing unit is presented vhich can be (?)sed for automatic analysis of Doppler echocardiogra(?)hic flow spectra. An algorithm based on greyvalue variation and its gradient is introduced for recognition of the contours of Doppler flow spectra, making the reproducibility and accuracy for automatic analysis of Doppler flow spectra significantly superior to those derived manually.
