Computed tomography (CT) reconstruction from X-ray projections acquired within a limited angle range is challenging, especially when the angle range is extremely small. Both analytical and iterative models need more projections for effective modeling. Deep learning methods have gained prevalence due to their excellent reconstruction performances, but such success is mainly limited within the same dataset and does not generalize across datasets with different distributions. Hereby we propose… Expand

DuDoTrans: Dual-Domain Transformer Provides More Attention for Sinogram Restoration in Sparse-View CT Reconstruction
Dual-Domain Transformer (DuDoTrans) is proposed to simultaneously restore informative sinograms via the longrange dependency modeling capability of Transformer and reconstruct CT image with both the enhanced and raw sinograms, which confirms the effectiveness and generalizability of DuDoTrans with fewer involved parameters.
