研究了模拟血液液体 (BMF) 的多普勒反向散射特性，以评估其在多普勒测试对象中的适用性。使用带有 C 柔性管的弓装置和由滚子泵或齿轮泵产生的 BMF 流进行测量。 SciMed 多普勒系统用于通过连接到音频输出的均方根功率计来测量反向散射多普勒功率。研究调查了 BMF 的反向散射多普勒功率与以下因素的依赖性： 循环时间；批次和操作员准备工作；贮存;筛子尺寸；流速；和泵类型。与重悬于盐水中的人类红血细胞进行比较。反向散射特性稳定且符合国际电工委员会的要求。 BMF 适用于多普勒性能评估的测试对象。 (C) 1998 年世界超声医学与生物学联合会。
The Doppler backscatter properties of a blood-mimickig fluid (BMF) were studied to evaluate its suitability for use in a Doppler how test object. Measurements were performed using a Bow rig with C-flex tubing and BMF flow produced by a roller pump or a gear pump. A SciMed Doppler system was used to measure the backscattered Doppler power with a root-mean-square power meter connected to the audio output. Studies investigated the dependence of the backscattered Doppler power of the BMF with: circulation time; batch and operator preparations; storage; sieve size; flow speed; and pump type. A comparison was made with human red bleed cells resuspended in saline. The backscatter properties are stable and within International Electrotechnical Commission requirements. The BMF is suitable for use in a test object for Doppler performance assessment. (C) 1998 World Federation for Ultrasound in Medicine & Biology.
