ISO 15708-2:20 17规定了X射线计算机断层扫描（CT）的一般原理、使用的设备以及样品、材料和几何形状的基本考虑因素。 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 15708-2:20 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 15708-2:2017 specifies the general principles of X-ray computed tomography (CT), the equipment used and basic considerations of sample, materials and geometry. 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 15708-2:2017 deals with computed axial tomography and excludes other types of tomography such as translational tomography and tomosynthesis.
