不同线对卡测试CT空间分辨率差异探讨

Explore of Different Line-pairs Test Spatial Resolution CT

    摘要
  • 摘要: 空间分辨率是描述工业CT系统性能的重要指标,目前测试方法有线对卡法和圆盘法,而线对卡没有统一的制作标准,常用的有条卡、圆孔形和方孔形等。本文通过理论分析和实验确定这些不同线对卡测试CT空间分辨率的结果差异及产生原因。

     

    Abstract: The spatial resolution of a CT system is important, but the two established methods to measure the spatial resolution, MTF and line-pairs. Make the line-pairs no unified standard, commonly use line-pairs has bar, hole and quadratic shape. In this paper, through theoretical analysis and test to determine the different line-pairs to test the results of the spatial resolution of CT differences and reasons.
