ISO 15708-4:2017规定了与各种检查任务有关的CT系统性能鉴定指南。它适用于工业成像（即非医疗应用），并给出一组一致的CT性能参数定义，包括这些性能参数与CT系统规范的关系。ISO15704-4:2017涉及计算轴向断层扫描和排除其他类型的断层扫描，如平移断层扫描和断层合成术。

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.
