We take into account the non-constant sample-to-detector distance for large samples by creating a 3D grid, where each pixel represents a distinct 2θ axis. The XRD-CT data, both the simulated and the experimental presented in the following sections, are interpolated using this 3D grid and subsequently their 3D Radon transform is calculated. The simulated data were created using a sample-to-detector distance of 1000 mm, translation step size of 0.2 mm, and a 100 keV X-ray energy. The simulated XRD-CT data consist of 121 translation steps, 121 projections covering 0-180 °angular range and 2000 scattering angles, which form a sinogram volume with the size 121 x 121 x 2000. ParallaxNet was used to reconstruct the whole dataset in ca. 7.4 h and 5000 epochs (iterations).
