X光图像的增强与复原

Enhancement and restoration of X-ray imaging

本文提出了两种X光图像处理方法,其中增强方法是运用调节参量在计算机上完成的,结果令人满意.复原法主要是在只考虑散射和光源尺寸的条件下来计算MTF(散射主要考虑增感屏的影响)在特殊情况下,可得到MTF的解析形式,它与计算机结果是一致的.

In this paper, we sug est a useful method of enhancement and restoration for X-ray imaging. Enhancement of X-ray imaging is done by adjusting paramenter in computer and result is satisfactory. MTF of X-ray images for stationary body is studid. For simplicity, only the degradation within the intensifying screens and the effects of the extended X-ray source size are considerd. We have described the specific analytic MTF in certain casses and results are agrement with foreig computing results.
