为了研究超声检测肿瘤的问题，拥有便携式多普勒血流测试对象作为标准化工具非常重要。血流多普勒测试对象旨在模拟人体动脉中的血流。为了使测试有意义，主要测试对象成分（组织和血液模拟物）的声学特性应与相应人体组织的特性密切匹配，而理想情况下管子的影响应很小。血液模拟物还应该代表血液的血液动力学特性。可接受的流量测试对象被设计为紧密模拟动脉中的血流。我们评估了三种仿血液体的特性：两种最近在文献中进行了描述，第三种是局部设计。其中之一与体外工作的必要特征特别匹配。
In order to investigate the problems of detecting tumours by ultrasound it is very important to have a portable Doppler flow test object to use as a standardising tool. The flow Doppler test objects are intended to mimic the flow in human arteries. To make the test meaningful, the acoustic properties of the main test object components (tissue and blood mimic) should match closely the properties of the corresponding human tissues, while the tube should ideally have little influence. The blood mimic should also represent the haemodynamic properties of blood. An acceptable flow test object has been designed to closely mimic blood flow in arteries. We have evaluated the properties of three blood mimicking fluid: two have been described recently in the literature, the third is a local design. One of these has emerged as being particularly well matched to the necessary characteristics for in-vitro work.
