Ultrasonic pulsed-Doppler signals from deep-lying vessels in the normal abdomen and pelvis are described. The signal characteristics combine to produce a Doppler "signature" that is specific for each vessel. The clinical potential of this method of deep flow detection is considered in relation to three areas of Doppler signal analysis: first, qualitative indication of the presence, direction, or absence of flow in a structure; second, more quantitative description of time velocity waveforms and Doppler spectral content; and third, the estimation of absolute volume flow. Limitations of these methods for the abdominal signals obtained are discussed.
描述了来自正常腹部和骨盆深处血管的超声脉冲多普勒信号。这些信号特征共同产生了一种特定于每条血管的多普勒“特征”。结合多普勒信号分析的三个方面，探讨了这种深部血流检测方法的临床潜力：第一，对结构中血流的存在、方向或缺失进行定性指示；第二，对时间速度波形和多普勒频谱内容进行更定量的描述；第三，估计绝对容积流量。讨论了这些方法在获取腹部信号方面的局限性。
