摘要： Ultrasound is used to provide input data for a blood pressure estimation scheme. The use of transcutaneous ultrasound provides arterial lumen area and pulse wave velocity information. In addition, ultrasound measurements are taken in such a way that all the data describes a single, uniform arterial segment. Therefore a computed area relates only to the arterial blood volume present. Also, the measured pulse wave velocity is directly related to the mechanical properties of the segment of elastic tube (artery) for which the blood volume is being measured. In a patient monitoring application, the operator of the ultrasound device is eliminated through the use of software that automatically locates the artery in the ultrasound data, e.g., using known edge detection techniques. Autonomous operation of the ultrasound system allows it to report blood pressure and blood flow traces to the clinical users without those users having to interpret an ultrasound image or operate an ultrasound imaging device.

摘要翻译：超声波用于提供血压估计方案的输入数据。使用经皮超声提供动脉管腔面积和脉搏波速度信息。另外，以这样的方式进行超声测量，使得所有数据描述单个均匀的动脉段。因此，计算区域仅与存在的动脉血容量相关。此外，测量的脉搏波速度与测量血容量的弹性管（动脉）的段的机械性质直接相关。在患者监视应用中，例如使用已知的边缘检测技术，通过使用自动定位超声数据中的动脉的软件来消除超声装置的操作者。超声系统的自主操作允许它向临床用户报告血压和血流迹线，而不需要用户解释超声图像或操作超声成像装置。
