摘要
通过介绍数字平板探测器的基本组成及特点,利用射线成像系统的基本理论,根据工业DR/CT系统的调制传递函数(modulation transfer function简称MTF),并对该函数进行进一步推导,结合平板探测器的特点,完成了成像系统的优化设计,并得到了较好的成像效果。实际系统设计表明,该方法具有通用性。
On the analysis of the essential composing and the characteristic of the digital flat panel detector,using the basic theory of radiographic system,the modulation transfer function of industrial DR/CT system was further deducted and improved.Combined with the characteristic of the digital flat panel detector,the improved design of radiographic system was finished and the better effect was obtained.The practical design showed that the method is of university.
