摘要

目的研究射线成像系统中对比度与分辨率的关系．方法用线性系统理论分析狭缝图像通过系统调制传递函数后对比度所受到的影响．结果对单缝和多缝两种情况进行分析，得到了对比度与分辨率的关系．结论所获得的结果在对疵病尺寸进行定理检测时有重要意义．

Abstract

Aim\ To study the relationship between contrast and spatial resolution in radiographic system. Methods\ According to the theory of linear system

how contrast of slots image is affected by modulation transfer function is analyzed. Results\ After analyzing one slot and multiple slots

the relationship between contrast and spatial resolution is abtainted. Conclusion\ The result is significant to the quantitative measurement of the size of flaw.
