Ring Artifacts Removal Based on Implicit Neural Representation of Sinogram Data
Ligen Shi, Xu Jiang, YunZe Liu +4
Inconsistent responses of X-ray detector elements lead to stripe artifacts in the sinogram data, which manifest as ring artifacts in the reconstructed CT images, severely degrading…

Iterative approach to reconstructing neural disparity fields from light-field data
Ligen Shi, Chang Liu, Xing Zhao +1
This study proposes a neural disparity field (NDF) that establishes an implicit, continuous representation of scene disparity based on a neural field and an iterative approach to a…

Ray-driven Spectral CT Reconstruction Based on Neural Base-Material Fields
Ligen Shi, Ping Yang, Chang Liu +3
In spectral CT reconstruction, the basis materials decomposition involves solving a large-scale nonlinear system of integral equations, which is highly ill-posed mathematically. Th…
