定义参数并概述测量脉冲回波医疗诊断系统性能的测试方法，该系统采用单元件传感器，并在0.5 MHz至25 MHz声频率范围内工作。为测量和报告完整诊断系统的主要性能参数提供了普遍可接受的基础。选择了规定的性能参数和相应的测量方法，以便为同类诊断应用中不同品牌的类似设备之间的比较提供依据。通过使用推荐方法获得的一组结果和值将为预测设备在适当诊断应用中的性能提供有用的标准。 为了使建议适用于一般应用，规定了不需要特殊和昂贵设备来实施的方法。如果一个基本诊断系统针对特定系统部件（如传感器）容纳多个选项，则在适当情况下，每个选项都应视为一个单独的系统。具有技术报告的状态。

Defines parameters and outlines test methods for measuring performance of pulse-echo medical diagnostic systems that employ single-element transducers and operate in the 0.5 MHz to 25 MHz acoustic frequency range. Provides a generally acceptable basis for measuring and reporting the principal performance parameters of complete diagnostic systems. The performance parameters specified, and the corresponding methods of measurement, have been chosen in order to provide a basis for comparison between similar apparatus of different makes intended for the same kind of diagnostic application. The set of results and values obtained from the use of the recommended methods will provide useful criteria for predicting the performance of equipment in appropriate diagnostic applications. In order that the recommendations should be suitable for general applications, methods have been specified which do not require unusual and expensive equipment for their implementation. Where one basic diagnostic system accommodates more than one option in respect of a particular system component, such as the transducer, it is intended that, wherever appropriate, each option be regarded as a separate system. Has the status of a technical report.
