摘要
医药行业标准YY/T 0481—2004《医用诊断X射线设备测定特性用辐射条件》在2012年进行了修订换版。该文首先通过比较新旧两个版本标准的主要变化内容来介绍了建立标准辐射质量和标准辐射条件所要重点解决的关键技术问题,包括辐射质量和辐射条件的表述、X射线管电压的测量,实用峰值电压的测量,然后介绍了标准辐射质量和辐射条件的建立程序。
The standard of YY/T 0481--2004 Medical diagnostic X ray equipment - Radiation conditions for use in the determination and characteristics has been revised and replaced in 2012. This paper first introduces the key technical problems to be solved in establishing standard radiation quality and radiation conditions by comparing the main changes of the two versions standards, including the expression of radiation quality and radiation conditions, the measurement of X ray tube voltage, and the measaring of the practical peak voltage. Then it introduces a procedure for establishing standard radiation quality and radiation conditions.
