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…
