摘要: A method for the reduction of artifacts based on an unequal representation same material classes in various locations, particular cupping artifacts, a three-dimensional image data set, reconstructed from two-dimensional x-ray projection images is provided. An datum, describing attenuation value, allocated respectively to voxel, wherein at least two class regions are located post-processing step, which receive, particular, data, homogeneously distributed and lies expected interval values, and, considering one characteristic regions, calculates smooth homogenization function, be applied entire set set.
