A testing system of DR based on the Flat-panel detector

The developing direction of X-ray testing system is to use the Flat-panel detector instead of film-screen images. Although the Flat-panel detector has many advantages, its image quality can't be better than that of film-screen (B level). By lots of experiments, the paper determines the best experiment conditions of imaging, analyzes the reasons for affecting the image quality and the performance of Flat-Panel detector, reduces noise at most. By applying the methods of imaging processing such as filtering and sharpening, the paper improves the image quality of Flat-panel, which is validated by a number of experiments of blade and IQI.
