Joint image reconstruction method with correlative multi-channel prior for X-ray spectral computed tomography (SOFTWARE)

The presented software reproduces numerical results of Inverse Problems journal paper. Software generates realisitic synthetic multi-energetic tomographic projection data and reconstructs it. Novel prior-correlative multi-channel algorithm is compared with other state-of-the-art reconstruction algorithms. Note that a GPU (Nvidia) card is required to use the software.
