| Abstract: | The degradation of radiography is one of the important factors, which results in degradation of inspecting sensitivity. By the restoration of radiography, the quality of radiographic image and inspecting sensitivity of radiographic system can be improved. After analyzed the effect and factors of degradation of radiography, the paper introduced the obtaining ways of point spread function and line spread function. The efficiency of restoration for a real high energy X ray radiographic image had being shown. |
