摘要
本文首先介绍了四种超声Ｄｏｐｐｌｅｒ血流信号最大频率估计的数字方法，然后讨论了如何利用最大频率的数字估计法自动提取血流声谱轮廓的方法。
In this paper four methods for digitally estimating the maximum frequency waveform from the Doppler ultrasound spectrum are first described. Then it is discussed how to automatically obtain the contours of Doppler flow sonogram by digital maximum frequency estimators.
