recommendations! Published in 2018 at "Measurement Science and Technology"

DOI: 10.1088/1361-6501/aa9dd9

Abstract: In synchrotron x-ray tomography, systematic defects in certain detector elements can result in arc-shaped artifacts in the final reconstructed image of the scanned sample. These ring artifacts are commonly found in many applications of synchrotron… read more here.

DOI: 10.1088/1361-6560/aa7017

Abstract: Ring artifacts in cone beam computed tomography (CBCT) images are caused by pixel gain variations using flat-panel detectors, and may lead to structured non-uniformities and deterioration of image quality. The purpose of this study is… read more here.

DOI: 10.1109/access.2020.2977096

Abstract: The development of energy-resolving photon-counting detectors provides a new approach for obtaining spectral information in computed tomography. However, the responses of different photon counting detector pixels can be inconsistent, which will always cause stripe artefacts… read more here.

DOI: 10.1109/tmi.2025.3545121

Abstract: In Computed Tomography (CT) imaging, the ring artifacts caused by the inconsistent detector response can significantly degrade the reconstructed images, having negative impacts on the subsequent applications. The new generation of CT systems based on… read more here.
