Visual comparison of the low-count denoised images from locally trained models and from our FedFTN. The local single model means FTN-modulated denoising networks trained at one specific low-count level at the specific institution. The local unified model means FTN-modulated denoising networks trained with all three low-count levels within each institution. The PET images with the lowest count levels at each institution are visualized here.
