| Abstract: | Objective To investigate the appearance, causes and countermeasures of the image artifacts in a computed radiographic system. Methods Random 1968 CR images were analyzed by GE Radworks. Results Among the 1,968 images which were choosed at random, 66 images with artifacts were found and processed. The artifacts in computed radiographic system are relevant to system software and hardware, dust as well as operators. Conclusion Familiarization with the appearance and causes of CR image artifacts helps to prevent or reduce artifacts. |
