VascuSR: Iterative Anatomy-Aware Diffusion for CT Super-Resolution

Researchers present VascuSR, an iterative anatomy-aware diffusion method for generative super-resolution of computed tomography (CT) images, addressing the problem that missing high-frequency content is not uniquely determined by low-resolution input and that visually plausible reconstructions may contain anatomical errors. The work targets recovery of sharp detail from severely downsampled CT observations.
