We now have development Python packages available from ASTRA git master on conda. : Windows Matlab/Python packages of the current 1.9.0.dev version of ASTRA git master are now available for download below. See the News section for more information. : In the latest development version of ASTRA (1.9.9.dev), we have made some consistency improvements to the grey value output ranges of the FP and BP operations. See the entry for in our News section for more information on these gray value output range consistency improvements. This official release wraps up all the consistency and compatibility improvements from the development releases over the past few years. The source code of the ASTRA Toolbox is available on GitHub. The basic forward and backward projection operations are GPU-accelerated, and directly callable from MATLAB and Python to enable building new algorithms. All of them have highly flexible source/detector positioning.Ī large number of 2D and 3D algorithms are available, including FBP, SIRT, SART, CGLS. We support 2D parallel and fan beam geometries, and 3D parallel and cone beam. The ASTRA Toolbox is a MATLAB and Python toolbox of high-performance GPU primitives for 2D and 3D tomography.
