TIGRE: Tomographic Iterative GPU-based Reconstruction Toolbox

TIGRE: Tomographic Iterative GPU-based Reconstruction Toolbox
TIGRE is a GPU accelerated software for big scale 3D tomographic reconstruction, being capable of reconstructing geometries such as Cone Beam Computed Tomography and Parallel Beam Computed Tomography.
TIGRE additionally includes a big set of iterative methods for image reconstruction, methods that can achieve better images with less projections. The algorithms included are:

-FDK (inverse radon)
-SART, OS-SART, SIRT (Gradient descend-based)
-CGLS (Krylov subspace based)
-ADS-POCS, OSC-POCS, B-ADS-POCS-β, SART-TV (Total variation regularization)
-MLEM (Statistical inversion)

TIGRE is released by University of Bath and CERN under a modified BSD license, making it available for everyone to use and modify, and the authors do encourage people to contribute to the code bug fixes, new methods or anything that can help it be better!
