为提高Doppler血流速度波形的信噪比,使用叠加法对此信号进行处理。本文报道作者在进行Doppler血流速度波形叠加处理中用软件检测同步信号的研究工作,首先介绍方法,然后报告实验结果。
To improve the signal-to-noise ratio of the Doppler blood flow velocity waveform, this signal is processed using the superposition method. This article reports the authors’ work on the detection of synchronization signals by software during the Doppler waveform superimposition, first of all introducing the method and then reporting the experimental results.
