SparseTokenGS: Gaussian-based Sparse-View CBCT Reconstruction via Reusable Token Pool
arXiv:2610.38360v1 Announce Type: cross Abstract: Sparse-view cone-beam computed tomography is widely used for fast, low-dose volumetric imaging and lesion localization in dentistry and image-guided interventions, but it introduces severe artifacts. Feed-forward Gaussian methods transfer the reconstruction cost to training and decode each coordinate from projection-aligned features and neighboring anchors. However, information from the whole scan is written only when the field is constructed an…
