MGMAR: Metal-Guided Metal Artifact Reduction for X-ray Computed Tomography

arXiv CS.AI

ArXi:2603.13447v1 Announce Type: cross An X-ray computed tomography (CT), metal artifact reduction (MAR) remains a major challenge because metallic implants violate standard CT forward-model assumptions, producing severe streaking and shadowing artifacts that degrade diagnostic quality. We propose MGMAR, a metal-guided MAR method that explicitly leverages metal-related information throughout the reconstruction pipeline. MGMAR first generates a high-quality prior image by
