PET image denoising based on denoising diffusion probabilistic models

Kuang Gong, Keith A. Johnson, Georges El Fakhri +2

Due to various physical degradation factors and limited counts received, PET image quality needs further improvements. The denoising diffusion probabilistic models (DDPM) are distr…

MR-Based PET Attenuation Correction using a Combined Ultrashort Echo Time/Multi-Echo Dixon Acquisition

Paul Kyu Han, Debra E. Horng, Kuang Gong +7

We propose a magnetic resonance (MR)-based method for estimation of continuous linear attenuation coefficients (LAC) in positron emission tomography (PET) using a physical compartm…
