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…
ReCo-Diff: Residual-Conditioned Deterministic Sampling for Cold Diffusion in Sparse-View CT
Yong Eun Choi, Hyoung Suk Park, Kiwan Jeon +2
Cold and generalized diffusion models have recently shown strong potential for sparse-view CT reconstruction by explicitly modeling deterministic degradation processes. However, ex…
An Iterative Reconstruction Method for Dental Cone-Beam Computed Tomography with a Truncated Field of View
Hyoung Suk Park, Kiwan Jeon
In dental cone-beam computed tomography (CBCT), compact and cost-effective system designs often use small detectors, resulting in a truncated field of view (FOV) that does not full…
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…
Neural Representation-Based Method for Metal-induced Artifact Reduction in Dental CBCT Imaging
Hyoung Suk Park, Kiwan Jeon, Jin Keun Seo
This study introduces a novel reconstruction method for dental cone-beam computed tomography (CBCT), focusing on effectively reducing metal-induced artifacts commonly encountered i…
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…
Automatic 3D Registration of Dental CBCT and Face Scan Data using 2D Projection Images
Hyoung Suk Park, Chang Min Hyun, Sang-Hwy Lee +2
This paper presents a fully automatic registration method of dental cone-beam computed tomography (CBCT) and face scan data. It can be used for a digital platform of 3D jaw-teeth-f…
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…
Unpaired image denoising using a generative adversarial network in X-ray CT
Hyoung Suk Park, Jineon Baek, Sun Kyoung You +2
This paper proposes a deep learning-based denoising method for noisy low-dose computerized tomography (CT) images in the absence of paired training data. The proposed method uses a…
CT sinogram-consistency learning for metal-induced beam hardening correction
Hyung Suk Park, Sung Min Lee, Hwa Pyung Kim +1
This paper proposes a sinogram consistency learning method to deal with beam-hardening related artifacts in polychromatic computerized tomography (CT). The presence of highly atten…
Characterization of Metal Artifacts in X-ray Computed Tomography
Hyoung Suk Park, Jae Kyu Choi, Jin Keun Seo
Metal streak artifacts in X-ray computerized tomography (CT) are rigorously characterized here using the notion of the wavefront set from microlocal analysis. The metal artifacts a…
