Shared-Structure 4D Spectral Gaussian Representation for Sparse-View Spectral CT Reconstruction
A SharedStructure 4D Spectral Gaussian Representation (4D-SG) is proposed that learns shared Gaussian geometry from full spectrum structural projections and uses a Gaussian-wise Spectral Density Curve Network (GSC-Net) to predict Gaussian raw density transformations.
