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.
