New Bayesian PET Reconstruction Uses Flow Matching Priors

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new Bayesian framework for positron emission tomography (PET) image reconstruction, addressing challenges like ill-posedness and noise in low-dose scans. This novel approach utilizes a generative prior learned through flow matching from high-quality PET images. The reconstruction is framed as a Bayesian inference problem, solved using latent-space posterior sampling with the unadjusted Langevin algorithm, offering improved performance and uncertainty quantification compared to existing methods.

    Bayesian PET Reconstruction with Learned Flow Matching Priors via Langevin Sampling

    arXiv:2610.41337v1 Announce Type: cross Abstract: Image reconstruction for positron emission tomography (PET) is a challenging inverse problem due to its inherent ill-posedness and Poisson counting noise, particularly in low-dose acquisitions. In this work, we introduce a novel B…
