1 Scope

This standard defines the terms of industrial computer tomography (CT) testing. This standard applies to industrial computer tomography (CT) testing and related fields.

2 general terms

2.1 Computed tomography computerized tomography A Method for Detecting Physical Features of Faults from Reconstructed Objects from Projection Data. Note. CT is called computed tomography in the medical field. 2.2 Industrial computer tomography industrialcomputedtomography; ICT Industrial CT Computer tomography for industrial applications. 2.3 Resolvingpower, resolution The ability of a CT system to discern the physical characteristics (structure or density) of an object. 2.4 Spatial resolution spatialresolvingpower Spatial resolution spatialresolution CT system to identify and distinguish the ability to measure the geometry of the measured object is a measure of the CT system is one of the main technical indicators, spatial resolution Usually in mm, the spatial resolution is usually in lp/mm. 2.5 Contrast sensitivity contrast sensitivity The ability of a CT system to distinguish the contrast between a given size area and the surrounding area in an object is limited by the system's signal-to-noise ratio. 2.6 Density resolution densityresolvingpower Density resolution densityresolution Under certain conditions, the capability of the CT system to distinguish the density of the specified size area from the surrounding area in the object is the main part of the CT system One of the technical indicators. 2.7 Artifact artifact CT images appear on the surface of the measured object structure, internal characteristics do not match the physical characteristics of the image. 2.8 CT number CTnumber CT image measurement, used to characterize the corresponding position of the CT image of the measured object and the reference object relative to the attenuation coefficient of radiation
