Coarse-to-Fine Registration of Jawbone CT and Intraoral Scan Data Using GeDi and ICP with Pseudo-IOS Ground Truth
Sho Mitarai, Hikaru Kayo, Hisashi Ozaki +2
In digital dentistry and oral surgery, the registration of jawbone CT and intraoral scanner (IOS) data is essential for integrating internal bone structure with high-resolution den…
Cone-Beam CT Image Quality Enhancement Using A Latent Diffusion Model Trained with Simulated CBCT Artifacts
Naruki Murahashi, Mitsuhiro Nakamura, Megumi Nakao
Cone-beam computed tomography (CBCT) images are problematic in clinical medicine because of their low contrast and high artifact content compared with conventional CT images. Altho…
Limited-Angle CT Reconstruction Using Multi-Volume Latent Consistency Model
Hinako Isogai, Naruki Murahashi, Mitsuhiro Nakamura +1
Limited-angle computed tomography (LACT) reconstruction is an inverse problem with severe ill-posedness arising from missing projection angles, and it is difficult to restore high-…
Construction of an Organ Shape Atlas Using a Hierarchical Mesh Variational Autoencoder
Zijie Wang, Ryuichi Umehara, Mitsuhiro Nakamura +1
An organ shape atlas, which represents the shape and position of the organs and skeleton of a living body using a small number of parameters, is expected to have a wide range of cl…
