MACE CT Reconstruction for Modular Material Decomposition from Energy Resolving Photon-Counting Data

Natalie M. Jadue, Madhuri Nagare, Jonathan S. Maltz +2

X-ray computed tomography (CT) based on photon counting detectors (PCD) extends standard CT by counting detected photons in multiple energy bins. PCD data can be used to increase t…

PPFM: Image denoising in photon-counting CT using single-step posterior sampling Poisson flow generative models

Dennis Hein, Staffan Holmin, Timothy Szczykutowicz +4

Diffusion and Poisson flow models have shown impressive performance in a wide range of generative tasks, including low-dose CT image denoising. However, one limitation in general,…
