Double-Constraint Diffusion Model with Nuclear Regularization for Ultra-low-dose PET Reconstruction
A frozen diffusion PET model outfitted with a low-rank nuclear transformer and dose-specific encoding controllers reconstructs ultra-low-dose images and selects the right controller when the dose is unknown.
