Clinical Metadata Guided Limited-Angle CT Image Reconstruction

ArXi:2509.01752v2 Announce Type: replace Limited-angle computed tomography (LACT) offers improved temporal resolution and reduced radiation dose for cardiac imaging, but suffers from severe artifacts due to truncated projections. To address the ill-posedness of LACT reconstruction, we propose a two-stage diffusion framework guided by structured clinical metadata. In the first stage, a transformer-based diffusion model conditioned exclusively on metadata, including acquisition parameters, patient graphics, and diagnostic impressions, generates coarse anatomical priors from noise.
