Realization of high-end PET devices that assist conventional PET devices in improving image quality via diffusion modeling
A diffusion model based on null-space constraints is a flexible framework that can effectively utilize the prior information provided by high-end scanners to improve the image quality of conventional scanners in cross-center and cross-device scenarios.
