DM4CT: Benchmarking Diffusion Models for Computed Tomography Reconstruction - Real-World Synchrotron CT Dataset
Creators
Description
This dataset contains synchrotron X-ray CT scans of two rock samples. For each sample, both the raw projection dataand the reconstructed slices are provided. The reconstructions include flat-field correction (using median dark and flat fields), log transformation, and ring artifact reduction.
This dataset accompanies the manuscript:
“DM4CT: Benchmarking Diffusion Models for Computed Tomography Reconstruction”
and is also suitable for evaluating other advanced CT reconstruction methods under realistic and practical conditions.
