DOI: 10.1002/jum.16748

Abstract: Repetitive valgus stress during pitching in baseball can lead to medial elbow instability. Although ring‐down artifact (RDA) has been considered an indicator of valgus instability, its pathological significance remains unclear. This study aimed to clarify… 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: 10.1107/s1600577522002739

Abstract: Streaks and Poissonian noise in tomography data are attenuated using a new two-stage multiscale volumetric filtering framework where the degradations are modeled as correlated noise. The procedure is fully automatic, offers improved feature preservation, and… 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.

DOI: 10.1371/journal.pone.0268410

Abstract: Ring artifact elimination is one of the popular problems in computed tomography (CT). It appears in the reconstructed image in the form of bright or dark patterns of concentric circles. In this paper, based on… read more here.
