Explore of Different Line-pairs Test Spatial Resolution CT

    Graphical Abstract
    • 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.
