ISO 15708-3:2017概述了计算机断层扫描（CT）系统的操作和结果解释，目的是为操作员提供技术信息，以便选择合适的参数。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。ISO157083:2017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 15708-3:2017 presents an outline of the operation of a computed tomography (CT) system and the interpretation of results with the aim of providing the operator with technical information to enable the selection of suitable parameters. 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 15708-3:2017 deals with computed axial tomography and excludes other types of tomography such as translational tomography and tomosynthesis.
