Residual Diffusion with Adaptive Data Consistency for Sparse-View CT Reconstruction

2026-07-03

Abstract excerpt

<title>Abstract</title> <p>Sparse-view computed tomography (CT) reduces radiation exposure by acquiring fewer projections but introduces severe streak artifacts due to incomplete angular sampling. Diffusion models offer expressive generative priors for reconstruction, yet conventional approaches typically initialize from Gaussian noise, requiring many reverse steps and incurring high inference cost. We propose a...
