标准摘要
[中文适用范围]: 本技术规范适用于医疗诊断超声领域。本技术规范规定: – 包含嵌入式热传感器以确定超声波加热的测试对象的重要特性和术语; – 为特定应用定义特定类型测试对象的要求; – 确保达到性能规范的设计特征示例; – 验证程序; – 使用测试对象确定标准化温升的一般测试方法。注 1:本技术规范特别涉及包含嵌入式热传感器(例如热电偶或热敏电阻)的测试对象。尽管可以使用非嵌入式温度测定方法来实现相同的目的,但这些超出了本技术规范的范围。注2:本技术规范中规定的测试对象用于测量温升,而不是用于确定热指数,根据定义,热指数是声场量的代数组合,因此不是物理可测量的量。 [外文原描述]: This Technical Specification is applicable to medical diagnostic ultrasonic fields.
