为解决国家和地区使用的X射线诊断辐射剂量仪及其相关X射线探测仪辐射计量的检定和校准问题,必须在全国范围内构建医学诊断X射线标准辐射场,提供标准辐射剂量值。按照IEC 61267医用诊断X射线设备辐射特性使用的条件标准,分析辐射质和标准辐射条件,介绍RQR、RQA、RQC、RQT、RQN、RQB、RQR-M、RQA-M、RQN-M、RQB-M的具体技术要求和建立方法 ,为国内计量部门、专业实验室、X射线设备生产企业提供建设方案和技术支持。
To solve the problem of test and calibration of X-ray diagnostic radiation dosimeter and its associated X-ray detection equipment used in China currently,standard medical diagnostic X-ray radiation fields must be built to provide the standard radiation dose values in whole the provinces. In accordance with IEC 61267 Medical diagnostic X-ray equipment-Radiation conditions for use in the determination of characteristics to analyze the radiation qualities and standards of radiation conditions,RQR,RQA,RQC,RQT,RQN,RQB,RQR-M,RQA-M,RQN-M and RQB-M are introduced as for specific technical requirements and the design methods to provide building programs and technical support for domestic Quality inspection agencies, specialized laboratories and the X-ray equipment manufacturers.
