ISO 15708-4:20 17规定了CT系统在各种检查任务方面的性能鉴定指南。 它适用于工业成像（即非医疗应用），并给出了一组一致的CT性能参数定义，包括这些性能参数与CT系统规格的关系。 ISO 15708-4:20 17涉及计算机轴向断层扫描，不包括其他类型的断层扫描，如平移断层扫描和断层合成。

ISO 15708-4:2017 specifies guidelines for the qualification of the performance of a CT system with respect to various inspection tasks. It is applicable to industrial imaging (i.e. non-medical applications) and gives a consistent set of CT performance parameter definitions, including how those performance parameters relate to CT system specifications. ISO 15708-4:2017 deals with computed axial tomography and excludes other types of tomography such as translational tomography and tomosynthesis.
