Please have a look at the requirements for running MITK Diffusion with all its features successfully!
The latest builds come as executable setup wizards that install MITK Diffusion on your system or alternatively as simple .tar.gz or .zip archive where you can execute MITK Diffusion and the command line apps "manually". You can find the newest installers here.
If you encounter any bugs, please report them here on github or use the MITK-users mailing list. We are grateful for any feedback!
For Windows users: MITK Diffusion requires the Microsoft Visual C++ 2017 Redistributable to be installed on the system. The MITK Diffusion installer automatically installs this redistributable for you if not already present on the system, but it needs administrative privileges to do so. So to install the redistributable, run the MITK Diffusion installer as administrator.

- Simulation of the k-space acquisition including
- Compartment specific relaxation effects
- Artifacts such as noise, spikes, ghosts, aliasing, distortions, signal drift, head motion, eddy currents and Gibbs ringing
- Definition of important acquisition parameters such as bvalues and gradient directions, TE, TR, dwell time, partial Fourier, ...
- Manual definition of fiber configurations, e.g. for evaluation purposes
- Automatic generation of random fiber configurations
Other features
- Integrated screenshot maker
- Command line tools for most functionalities
- Great python package for logging your (MITK or other) command line experiments:

pip3 install cmdint
- TractSeg reference data of 72 semiautomatically defined bundles in 105 HCP subjects: https://zenodo.org/record/1285152
- TractSeg python package: https://github.com/MIC-DKFZ/TractSeg
- Simulated dMRI images and ground truth of random fiber phantoms in various configurations: https://doi.org/10.5281/zenodo.2533250
- ISMRM 2015 Tractography Challenge Data: https://doi.org/10.5281/zenodo.572345 & https://doi.org/10.5281/zenodo.1007149
Illustration of simulated dMRI images with various artifacts (a bit excessive for illustration purposes): eddy current distortions (1), motion and spike (2), intensity drift (3), motion, eddy and noise (4), ringing (5), B0 inhomogeneity distortions (6), from left to right.
Please not that we moved away from a separate MITK Diffusion application and are instead building configurations of the MITK Workbench. In a (near)-future version of MITK, customizations of the Workbench will be possible to change the display and executable name etc. A workaround is to use the MITK branch https://github.com/MITK/MITK/tree/feature/T30337-WorkbenchCustomizations2, which already enables some of those customizations but the final mechanism fot that will be different.
-
Install Qt on your system (currently 6.6.1).
-
Clone MITK from github using Git version control.
-
Clone MITK Diffusion from github.
-
Configure the MITK Superbuild using CMake.
- Choose the MITK source code directory and an empty binary directory.
- Click "Configure".
- Set the option MITK_EXTENSION_DIRS to "/path/to/my/mitk-diffusion-repository".
- Click "Configure".
- Set the option MITK_BUILD_CONFIGURATION to "DiffusionRelease" or any other desired configuration. There are various configurations to build e.g. only IVIM modules or only tractography. The DiffusionRelease/DiffusionDebug configurations contain all modules.
- Click "Generate".
-
Start the Superbuild:
- Linux: Open a console window, navigate to the build folder and type "make -j8" (optionally supply the number threads to be used for a parallel build with -j).
- Windows (requires visual studio): Open the MITK Superbuild solution file and build all projects.
- The Superbuild may take some time.
- After the Superbuild has finished, change the cmake binary directory from "/path/to/my/build" to "/path/to/my/build/MITK-build" and configure+generate again.
- Build again in "/path/to/my/build/MITK-build" using make (linux/mac) or the VS solution file.
- The build may again take some time and should yield the binaries in "/path/to/my/build/MITK-build/bin"
More detailed build instructions can be found in the documentation.
