A review is given of quantitative techniques and clinical applications of arterial Doppler ultrasound. The currently available Doppler equipment of stand-alone continuous wave and pulsed wave units, duplex systems and colour flow systems is briefly described. Doppler ultrasound can be divided into procedures concerned with waveform analysis, volume flow measurement and more recently colour flow imaging. Arterial Doppler waveform analysis is considered for a number of areas including carotid, lower limb, renal and renal transplant, obstetrics, adult cerebral, neonatal cerebral, and tumour studies. Using a duplex scanner volume flow in arteries can be measured from estimates of vessel cross sectional area, mean Doppler frequency and beam-vessel angle. The errors associated with each of these measurements is discussed, and reports of experimentally determined in vivo accuracy of volume flow measurements made using this technique are considered. Other volume flow measurement techniques including the promising attenuation compensation method are also explored.
本文综述了动脉多普勒超声的定量技术及其临床应用。简要介绍了目前可用的独立连续波和脉冲波单元、双功系统和彩色血流系统等多普勒设备。多普勒超声可分为与波形分析、血流量测量以及最近的彩色血流成像相关的检查方法。动脉多普勒波形分析应用于多个领域，包括颈动脉、下肢、肾脏及肾移植、产科、成人脑部、新生儿脑部以及肿瘤研究。使用双功扫描仪，可以通过估计血管横截面积、平均多普勒频率和波束与血管夹角来测量动脉血流量。讨论了与这些测量相关的误差，并考虑了关于使用该技术进行体内血流量测量的实验确定准确性的报告。还探讨了其他血流量测量技术，包括有前景的衰减补偿法。
