Poisson diffusion probabilistic model for low‐dose SPECT sinogram denoising
The proposed PDPM demonstrates promising performance in the denoising of low-dose SPECT sinograms. We presented a preliminary framework for PDPM and refined it to create the final version of PDPM, which is designed for the task of low-dose SPECT sinogram denoising. Our PDPM achieved favorable denoising results on both simulated and clinical datasets.
