Splat-based Metal Artifact Reduction in Cone-Beam CT via Polychromatic Modeling
Kiseok Choi, Inchul Kim, Jaemin Cho +2
Cone-beam computed tomography (CBCT) enables volumetric reconstruction from X-ray projections, but suffers from severe artifacts--especially beam hardening--when imaging materials…
Splat-Based Metal Artifact Reduction in Cone-Beam CT via Compact Attenuation Modeling
Kiseok Choi, Jaemin Cho, Inchul Kim +1
X-ray computed tomography (CT) suffers from severe metal artifacts when high-attenuation objects such as dental fillings or orthopedic implants are present. These artifacts origina…
Revisiting Pose Sensitivity in Splat-based Computed Tomography under Sparse-view Reconstruction
Kiseok Choi, Hyeongjun Cho, Inchul Kim +1
X-ray computed tomography (CT) reconstructs volumetric representations of objects from projection images obtained by transmitting X-rays through a target. Recent splat-based tomogr…
Benchmarking Burst Super-Resolution for Polarization Images: Noise Dataset and Analysis
Inseung Hwang, Kiseok Choi, Hyunho Ha +1
Snapshot polarization imaging calculates polarization states from linearly polarized subimages. To achieve this, a polarization camera employs a double Bayer-patterned sensor to ca…
