数字辐射扫描成像系统水平分辨率的提高

Improvement of horizontal resolution in digital radiography system

对辐射成像无损检测系统中的水平采样模型和模糊影响进行了分析 ,提出重叠采样提高水平扫描分辨率的方法 ,并通过实验测量水平冲击响应函数 ,利用逆滤波算法对采样模糊后的图像进行了恢复。

This paper analyzes horizontal sampling model of digital radiography system and presents the overlap sampling method to improve horizontal resolution. Horizontal pulse response function are given through experiment measurement. Inverse filtering method is used to restore image blurred by overlap sampling and get good result.
