PROBLEM TO BE SOLVED: To provide an image reconstruction processing method and an image processing method that can reduce noises even when spatial correlativity of an error occurring in an image is strong.SOLUTION: Being different from a conventional technique regularizing a differential space of an image, regularization function evaluating a degree of mutual similarity of a weighted addition value along a linear space is used to perform reconstruction processing and prepare a digital image of a plurality of dimensions after the reconstruction processing is performed. That is, processing (regularization process) for regularizing a projection space is performed by incorporating the regularization process to the reconstruction processing. In this case, a line integrated value corresponding to the weighted addition value is obtained along a streak artifact SA occurring along the linear space. The regularization function described in the above is used to perform the reconstruction processing and prepare the digital image of the plurality of dimensions after the reconstruction processing is performed, and thus, noise can be reduced even when spatial correlativity of an error occurring in the image is strong.SELECTED DRAWING: Figure 7 |
