摘要：

Tomographic images are often superimposed by so called ring artefacts. Ring artefacts are concentric rings in the images around the center of rotation of the tomographic setup caused e. g. by differences in the individual pixel response of the detector. They complicate the post processing of the data, i.e. the segmentation of individual image information. Hence, for a quantitative analysis of the tomographic images a significant reduction of these artefacts is essential. In this paper, a simple but efficient method to eliminate such artefacts during the reconstruction is proposed. (c) 2006 Optical Society of America.
