The element response inconsistency of flat-panel detector may result in ring artefacts in cone-beam CT image reconstruction. Ring artefacts severely affect the quality of CT reconstructed image, thus removing ring artefacts is very meaningful for image analysis and subsequent processing. This paper presents an algorithm for processing reconstructed image, and has achieved a result through simulating. This approach proves very effective in removing ring artefacts from images.
