The authors employed input vascular impedance measurements, based on the non-invasive ultrasound measurements of blood flow and pressure in common carotid artery, to evaluate human cerebro-vascular system. An analysis involved a 4-element substitute model of vascular system which included: compliance, inertia, vascular resistance, and peripheral resistance. Preliminary clinical examination of both sick and healthy individuals indicate that total real resistance measured in the common carotid artery depends on the patency of branching arteries. At the same time, ratio of vascular resistance Ro do peripheral resistance Rp may be an indicator of the atheromatous lesions to the arteries below measurement point. Ratio Ro greater than 0.5 is being considered as an index of pathology.
作者采用基于无创超声测量颈总动脉血流和压力的输入血管阻抗测量方法，来评估人体脑血管系统。分析涉及一个由四个元件组成的血管系统替代模型，该模型包括：顺应性、惯性、血管阻力和外周阻力。对患病个体和健康个体的初步临床检查表明，在颈总动脉中测得的总实际阻力取决于分支动脉的通畅情况。同时，血管阻力Ro与外周阻力Rp之比可能是测量点以下动脉粥样病变的一个指标。Ro大于0.5的比值被视为病理学指标。
