The ASTRA Toolbox provides high-performance GPU primitives for 2D and 3D tomography. It supports 2D parallel and fan beam, and 3D parallel and cone beam geometries. All of them have highly flexible source/detector positioning. A large number of 2D and 3D algorithms are available, including FBP, SIRT, SART, CGLS. The basic forward and backward projection operations are GPU-accelerated, and directly callable from Python to enable building new algorithms.
If you use the ASTRA Toolbox for your research, we would appreciate it if you would refer to the following papers:
