The ASTRA Toolbox

The ASTRA Toolbox is a MATLAB and Python toolbox of high-performance GPU primitives for 2D and 3D tomography.

We support 2D parallel and fan beam geometries, and 3D parallel and cone beam. 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 MATLAB and Python to enable building new algorithms.

Installation instructions

Windows, binary

Add the mex and tools subdirectories to your MATLAB path, or copy the Python astra module to your Python site-packages directory. We require the Microsoft Visual Studio 2015 redistributable package. If this is not already installed on your system, it is included as vc_redist.x64.exe in the ASTRA zip file.

Linux/Windows, using conda for python

Requirements: conda python environment, with 64 bit Python 2.7, 3.5 or 3.6.

There are packages available for the ASTRA Toolbox in the astra-toolbox channel for the conda package manager. To use these, run the following inside a conda environment.

conda install -c astra-toolbox astra-toolbox

Linux, from source

For Matlab

Requirements: g++, boost, CUDA (5.5 or higher), Matlab (R2012a or higher)

cd build/linux
./autogen.sh   # when building a git version
./configure --with-cuda=/usr/local/cuda \
            --with-matlab=/usr/local/MATLAB/R2012a \
            --prefix=$HOME/astra \
            --with-install-type=module
make
make install

Add $HOME/astra/matlab and its subdirectories (tools, mex) to your matlab path.

If you want to build the Octave interface instead of the Matlab interface, specify --enable-octave instead of --with-matlab=... . The Octave files will be installed into $HOME/astra/octave .

NB: Each matlab version only supports a specific range of g++ versions. Despite this, if you have a newer g++ and if you get errors related to missing GLIBCXX_3.4.xx symbols, it is often possible to work around this requirement by deleting the version of libstdc++ supplied by matlab in MATLAB_PATH/bin/glnx86 or MATLAB_PATH/bin/glnxa64 (at your own risk), or setting LD_PRELOAD=/usr/lib64/libstdc++.so.6 (or similar) when starting matlab.

For Python

Requirements: g++, boost, CUDA (5.5 or higher), Python (2.7 or 3.x)

cd build/linux
./autogen.sh   # when building a git version
./configure --with-cuda=/usr/local/cuda \
            --with-python \
            --with-install-type=module
make
make install

This will install Astra into your current Python environment.

macOS, from source

Use the Homebrew package manager to install boost, libtool, autoconf, automake.

cd build/linux
./autogen.sh
CPPFLAGS="-I/usr/local/include" NVCCFLAGS="-I/usr/local/include" ./configure \
  --with-cuda=/usr/local/cuda \
  --with-matlab=/Applications/MATLAB_R2016b.app \
  --prefix=$HOME/astra \
  --with-install-type=module
make
make install

Windows, from source using Visual Studio 2015

Requirements: Visual Studio 2015 (full or community), boost (recent), CUDA 8.0, Matlab (R2012a or higher) and/or WinPython 2.7/3.x.

Using the Visual Studio IDE:

Set the environment variable MATLAB_ROOT to your matlab install location. Copy boost headers to lib\include\boost, and boost libraries to lib\x64. Open astra_vc14.sln in Visual Studio. Select the appropriate solution configuration (typically Release_CUDA|x64). Build the solution. Install by copying AstraCuda64.dll and all .mexw64 files from bin\x64\Release_CUDA and the entire matlab/tools directory to a directory to be added to your matlab path.

Using .bat scripts in build\msvc:

Edit build_env.bat and set up the correct directories. Run build_setup.bat to automatically copy the boost headers and libraries. For matlab: Run build_matlab.bat. The .dll and .mexw64 files will be in bin\x64\Release_Cuda. For python 2.7/3.5: Run build_python27.bat or build_python35.bat. Astra will be directly installed into site-packages.

Testing your installation

To perform a (very) basic test of your ASTRA installation in Python, you can run the following Python command.

import astra
astra.test()

To test your ASTRA installation in Matlab, the equivalent command is:

astra_test
