Datasets were used to demonstrate the improvement of a tomographic data after distortion correction was applied. Details in the conference paper: Nghia T. Vo, Robert C. Atwood, and Michael Drakopoulos "Preprocessing techniques for removing artifacts in synchrotron-based tomographic images", Proc. SPIE 11113, Developments in X-Ray Tomography XII, 111131I (10 September 2019); https://doi.org/10.1117/12.2530324 Distortion coefficients were calculated using vounwarp package: https://github.com/DiamondLightSource/vounwarp/blob/master/vounwarp/examples/example_01.py Slices can be reconstructed using the Savu pipeline: flat-field correction, distortion correction, center of rotation calculation, ring artifact removal, and FBP reconstruction.
