Background Dental hardware produces streak artifacts on computed tomography (CT) images reconstructed with the standard weighted filtered back projection (wFBP) method. Purpose To perform a preliminary evaluation of an iterative metal artifact reduction (IMAR) technique to assess its ability to improve anatomic visualization over wFBP in patients with dental amalgam or other hardware. Mater...
For the task of metal artifact reduction (MAR), although deep learning (DL)-based methods have achieved promising performances, most them suffer from two problems: 1) CT imaging geometry constraint is not fully embedded into network during training, leaving room for further performance improvement; 2) model interpretability lack sufficient consideration. Against these issues, we propose a novel...
