标准摘要
[中文适用范围]： 本文件规定了计算机放射线照相的基本技术，旨在经济地获得令人满意且可重复的结果。 这些技术基于该主题的基本理论和测试测量。 本文件规定了使用存储荧光成像板 (IP) 进行缺陷检测的工业计算 X 射线和伽马射线照相的一般规则。 它基于 ISO 5579 中规定的基于胶片的金属材料射线照相检查的一般原则。 辐射源、探测器和相应几何形状的基本设置旨在按照 ISO 5579 和相应的产品标准，例如焊接 ISO 17636 和铸造 EN 12681。 本文件没有规定缺陷的验收标准。 计算机放射线照相（CR）系统提供只能在计算机上查看和评估的数字灰度值图像。 本实践描述了探测器选择和射线照相实践的推荐程序。 计算机、软件、显示器、打印机和查看条件的选择很重要，但不是本文档的重点。 它指定的程序提供了允许曝光和采集数字射线照片的最低要求和实践，其缺陷检测灵敏度与胶片射线照相相当，并且符合 ISO 5579 中的规定。 某些应用标准，例如 EN 16407，可能需要不同的且不太严格的标准。 练习条件。 [外文原描述]： ISO 16371-2:2017 specifies fundamental techniques of computed radiography with the aim of enabling satisfactory and repeatable results to be obtained economically. The techniques are based on the fundamental theory of the subject and tests measurements. ISO 16371-2:2017 specifies the general rules for industrial computed X-rays and gamma radiography for flaw detection purposes, using storage phosphor imaging plates (IP). It is based on the general principles for radiographic examination of metallic materials on the basis of films, as specified in ISO 5579. The basic set-up of radiation source, detector and the corresponding geometry are intended to be applied in accordance with ISO 5579 and corresponding product standards such as ISO 17636 for welding and EN 12681 for foundry. ISO 16371-2:2017 does not lay down acceptance criteria of the imperfections. Computed radiography (CR) systems provide a digital grey value image which can be viewed and evaluated on basis of a computer only. This practice describes the recommended procedure for detector selection and radiographic practice. Selection of computer, software, monitor, printer and viewing conditions are important but not the main focus of ISO 16371-2:2017. The procedure it specifies provides the minimum requirements and practice to permit the exposure and acquisition of digital radiographs with a sensitivity of imperfection detection equivalent to film radiography and as specified in ISO 5579. Some application standards, e.g. EN 16407, can require different and less stringent practice conditions.
