The clinical information available from ultrasonic Doppler blood velocimeters may be analysed in several ways, spectral analysis probably being the best. This is, however, a relatively expensive technique when compared with the cost of commerically available Doppler velocimeters. A large part of the diagnostic information present can be obtained from the maximum blood velocity in the vessel at any one time. A relatively inexpensive analogue method of extracting this information from the Doppler signal is described, and the preliminary results obtained on signals derived from peripheral arteries are discussed.
从超声多普勒血流速度计获取的临床信息可以通过多种方式进行分析，频谱分析可能是最佳方式。然而，与市售多普勒速度计的成本相比，这是一种相对昂贵的技术。现有的大部分诊断信息可以从血管中任一时刻的最大血流速度获得。本文描述了一种从多普勒信号中提取此信息的相对廉价的模拟方法，并讨论了从外周动脉获得的信号的初步结果。
