| 摘 要： | 2012年以来我国发布了一系列关于工业CT的国家标准。虽然起到了相当的积极作用,但是仍然暴露出一些明显的不足之处。本文就名词术语标准的制定、空间分辨率的检测条件、对比度分辨率、低对比度空间分辨率、加强对于圆盘模体测定技术的研究和测定透射散射比等问题提出若干修订的建议。

| 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. |

| Keywords: | computed tomography spatial resolution contrast resolution low-contrast spatial resolution disk phantom transmission to scattering ratio |
