摘　　要：对于以影象增强器为检测系统的目标旋转式工业ＣＴ，分析了其图象退化的因素，采用对一维投影数据进行图象恢复的方法来提高ＣＴ图象质量。文中给出图象恢复公式，从计算机模拟和实验图象恢复的结果可看到所用方法提高了图象清晰度。The factors that causing the image degradation during the imaging procedure, was analysed for the industrial CT with the way of object rotation, using a detective system combined by image intensifier and digital TV system. The image restoration was implemented in one dimension projection data to improve the quality of CT image. The formula of restoration was given. We can see that using this method the clearness was improved from the results of computer simulation and experimental image restoration.
