最大熵法重建CT图像

Maximum Entropy Method for the Reconstruction of CT Image

摘要: 针对现有CT设备上重建图像存在的"伪影"问题,提出了用最大墒法重建CT图像.鉴于现成的CT设备数据之间严格的关系难以找到,设计了模拟投影数据,用最大熵法重建图像的全软件,并针对二值图像进行了实验,得出了相应的结论.

Abstract: There is "pseudo-lines" in some CT images. To solve this problem, the Maximum Entropy Method is introduced for the reconstruction of CT image. In view of the difficulty to figure out the strict relation between projection data and CT image, the simulation data is adoped. Besides all the software in question is designed, and the experimental result the conclusion from it are give as well.
