Abstract

Since 2012 a set of National Standards on Industrial Computed Tomography has been issued in China. Although they have taken some active effect, a lot of obvious deficiency is exposed. In this paper some proposals of revise about definition of technical terms, testing condition of spatial resolution, contrast resolution, low-contrast spatial resolution, study of testing using disk phantom, measure of transmission to scattering ratio etc. are presented.
- computed tomography,
- spatial resolution,
- contrast resolution,
- low-contrast spatial resolution,
- disk phantom,
- transmission to scattering ratio
