CT-Conditioned Diffusion Prior with Physics-Constrained Sampling for PET Super-Resolution
arXiv CS.CV
•
ArXi:2603.13901v1 Announce Type: new PET super-resolution is highly under-constrained because paired multi-resolution scans from the same subject are rarely available, and effective resolution is determined by scanner-specific physics (e.g., PSF, detector geometry, and acquisition settings). This limits supervised end-to-end
