Reconstructing 3D voxels from ultra-sparse-view 2D X-ray images using a dual-domain balanced network
Ultra-sparse cone-beam computed tomography (CBCT) reconstruction is important for low-dose and rapid 3D imaging, including C-arm-assisted interventions, yet the Feldkamp-Davis-Kress (FDK) algorithm and simultaneous iterative reconstruction technique (SIRT) degrade under sparse views. We propose a cross-domain framewo...
