基于探测器宽度的FBP改进算法

An Improved FBP Arithmetic Based on Detector’s Width

    摘要
  • 摘要: 在实际的CT重建过程中,探测器是有大小的,如果我们在重建算法设计中考虑到这一点,对重建图像来说,将会得到更多更精确的信息量。本文针对实际探测器的结构特点,提出一种新的改进FBP重建算法,将算法与实际结合,并通过实际的工业CT系统进行实验。实验结果表明,改进方法重建出的图像边缘和细节都要比未改进的方法好,而且还有抑制噪声的作用,对工业CT的实际应用有一定的意义。

     

    Abstract: In the process of practical CT reconstruction,the detector has its size.We will get more accurate information for reconstruction if we take it into our account,when we design our reconstruction arithmetic.Based on the detector’s structure,this paper gives a new improved FBP-Arithmethm,and we take it into practical experiment.The outcome indicates that the improved FBP-Arithmethm will give a better result in the reconstructed image’s edge and detail information.Also has the effect of restrain the yawp,it will have some significance in the practical ICT system.
