| Abstract(in English) | A number of coded aperture imaging(CAI) techniques have been used or proposed for X-ray imaging. In URA(Uniformly redundant array) camera, the pinhole is replaced by multi-pinholes arrays arranged in m-sequences. Since the URA camera can view the object with a large solid angle, it can also provide some tomographic resolution for three-dimensional object. Since the reconstructed tomographic images contain serious defocus artifacts, we propose a new method based on SA to reconstruct the tomographic images from the coded image and we also propose a fast algorithm to reduce the large computation cost. Since the complicated a priori constraints can be easily incorporated by the appropriate modification of the cost function in SA-based method. it is well suited for reconstruction from to noisy coded images. |
