The ultrasonic duplex system, which is composed of a pulsed Doppler flowmeter and a linear array B-mode scanner, was developed for the purpose of quantitative transcutaneous measurement of blood flow. It was applied here to the study of portal blood flow in a normal series with healthy volunteers as subjects. A preliminary experiment, prepared by setting up a simulation model for blood circulation, demonstrated an excellent correlation between values obtained with the electromagnetic flowmeter (EMF) and the combined ultrasonic B-mode and Doppler system (duplex system). This was confirmed in vivo in a study of blood flow in the canine vena cava. The portal blood flow in 88 healthy adult volunteers ranging in age from 18 to 55 years (average 34.3) was studied using this equipment. Blood flow in fasting subjects who were resting was 889 +/- 284 ml/min (mean +/- SD) or 16.3 +/- 5.0 ml/min/kg body weight (mean +/- SD).
超声双功系统由脉冲多普勒流量计和线性阵列B型扫描仪组成，旨在定量经皮测量血流。本研究以健康志愿者为正常对照组，将该系统应用于门静脉血流的研究。通过建立血液循环模拟模型进行的初步实验表明，电磁流量计（EMF）与超声B型和多普勒联合系统（双功系统）所测值之间具有良好的相关性。在犬腔静脉血流研究中，这一结果在体内得到了证实。使用该设备对88名年龄在18至55岁（平均34.3岁）的健康成年志愿者的门静脉血流进行了研究。静息空腹受试者的血流为889±284 ml/分钟（平均值±标准差）或16.3±5.0 ml/分钟/千克体重（平均值±标准差）。
