Extremely Sparse-View Computed Tomography from 2D Projections via Pose-Aware Diffusion Priors
arXiv:2610.38319v1 Announce Type: cross Abstract: Extremely sparse-view computed tomography (xSV-CT) is critical when scanning time, motion, or radiation tolerance limits each scan to only a few projections. In many such scenarios, the same acquisition limits also constrain dataset construction, making pre-reconstructed 3D volumes from dense scans unavailable. This exposes a gap in current sparse-view approaches: Optimization-based methods, which use the sparse measurements directly but lack da…
