MGMAR: Metal-Guided Metal Artifact Reduction for X-ray Computed Tomography
Hyoung Suk Park, Kiwan Jeon
An X-ray computed tomography (CT), metal artifact reduction (MAR) remains a major challenge because metallic implants violate standard CT forward-model assumptions, producing sever…
Adaptive Multi-resolution Hash-Encoding Framework for INR-based Dental CBCT Reconstruction with Truncated FOV
Hyoung Suk Park, Kiwan Jeon
Implicit neural representation (INR), particularly in combination with hash encoding, has recently emerged as a promising approach for computed tomography (CT) image reconstruction…
A robust multi-domain network for short-scanning amyloid PET reconstruction
Hyoung Suk Park, Young Jin Jeong, Kiwan Jeon
This paper presents a robust multi-domain network designed to restore low-quality amyloid PET images acquired in a short period of time. The proposed method is trained on pairs of…
Nonlinear ill-posed problem in low-dose dental cone-beam computed tomography
Hyoung Suk Park, Chang Min Hyun, Jin Keun Seo
This paper describes the mathematical structure of the ill-posed nonlinear inverse problem of low-dose dental cone-beam computed tomography (CBCT) and explains the advantages of a…
Metal Artifact Reduction with Intra-Oral Scan Data for 3D Low Dose Maxillofacial CBCT Modeling
Chang Min Hyun, Taigyntuya Bayaraa, Hye Sun Yun +3
Low-dose dental cone beam computed tomography (CBCT) has been increasingly used for maxillofacial modeling. However, the presence of metallic inserts, such as implants, crowns, and…
