International audienceIn X-ray Computed Tomography, ring artifacts can be caused by imperfect elements in a detector or also by defects or impurities in the scintillator's crystals. The artifacts appear on Computed Tomographic images as concentric rings superimposed on the images of the structures being scanned. The presence of such artifacts significantly complicates the post processing techniques such as noise reduction, binarization, or segmentation of image information. The efficacy of these techniques depends on the consistency of the method of classification and detection of ring artifacts. In this paper we present a simple, fast and efficient method to detect ring artifacts on Computed Tomographic images in the Polar domain
