ISO 16371-2:2017规定了计算机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。这些技术是基于主题的基本理论和测试测量。ISO 16371-2:2017规定了使用存储荧光成像板（IP）进行工业计算X射线和伽马射线探伤的一般规则。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、探测器和相应几何结构的基本设置应符合ISO 5579和相应的产品标准，如ISO 17636焊接标准和EN 12681铸造标准。 ISO 16371-2:2017未规定缺陷的验收标准。计算机射线照相（CR）系统提供数字灰度图像，仅可在计算机上查看和评估。 本规程描述了探测器选择和射线照相规程的推荐程序。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ISO 16371-2:2017的主要重点。 其规定的程序提供了允许曝光和获取数字射线照片的最低要求和实践，其缺陷检测灵敏度相当于胶片射线照相，并符合ISO 5579的规定。一些应用标准，例如EN 16407，可能要求不同且不太严格的实践条件。

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.
