| Abstract: | In this paper,a new image reconstruction algorithm named maximum entropy reprojecting is developed for missing projection data from some objects are opaque for parts of ray.The results of comparing simulation experiments on the general computer indicate that the quality of reconstructed images by the new algorithm are much better than the tradional maximum entropy algorithm.So the algorithm has reliable propect in application. |
