Ultra-sparse-view cone-beam CT (CBCT) acquisition reduces imaging dose in image-guided radiotherapy; however, extreme angular sparsity introduces severe streak artifacts and structural inconsistency that challenge conventional and learning-based reconstructio...

To generate physiologically plausible 4D medical image sequences from extremely sparse inputs by integrating external breathing signals, overcoming the limitation of requiring dense supervision in current spatiotemporal interpolation methods.
