Propagation-based phase-contrast X-ray computed tomography (PB-PC-CT) offers superior contrast for materials with similar absorption properties over conventional methods, but its phase retrieval is challenging. Relying on multiple measurements increases radiation dose, while single-measurement techn...

In computed tomography (CT), metal artifacts pose a persistent challenge to achieving high-quality imaging. Despite advancements in metal artifact reduction (MAR) techniques, many existing approaches have not fully leveraged the intrinsic a priori knowledge related to metal artifacts, improved model...

X-ray scatter presents a significant challenge in computed tomography (CT) by introducing artifacts and diminishing contrast, ultimately affecting measurement accuracy in reconstructed images. While Monte Carlo (MC) simulation is the gold standard for scatter correction, its high computational cost ...
