A new signal processing approach to estimation of local arterial pulse wave velocity (PWV) in superficial arterial segments using long-axis ultrasound measurements is proposed. The method is designed to be resistant to estimation bias due to pulse wave reflections. It is evaluated using a laboratory test tank, and it appears to estimate local PWV with less bias than previously accepted methods, and with similar estimation variance to those methods.
提出了一种新的信号处理方法，用于通过长轴超声测量来估计浅表动脉段的局部动脉脉搏波速度（PWV）。该方法旨在抵抗由于脉搏波反射引起的估计偏差。使用实验室测试槽对其进行了评估，结果表明，与先前公认的方法相比，该方法估计局部PWV时偏差更小，且估计方差与那些方法相似。
