MITK v2024.12
News for MITK Workbench users
We are proud to release MITK v2024.12. In the past 6 months we resolved about 200 tasks and issues in over 300 commits. While our winter releases tend to be manily bugfix releases, we take the opportunity to highlight several new features and quality of life improvements in these release notes. You find the complete changelog at the end of this release notes.
Segmentation
Rename label groups
Labels can be organized in groups (used to be named "layers" in the past). In fact it is the only way to create overlapping labels, since labels within a group cannot share the same pixels. It is now possible to rename groups, which otherwise have generic default names like "Group 1".
Decrease label opacity
User feedback showed that opinions on a good opacity of segmentations vary greatly. If you prefer to work with less label opacity to still clearly see the labeled pixels below, you can now dial down the "Opacity factor" in the Segmentation preference page.
Create smoothed polygon models (fast)
Hidden in the context menu of the Data Manager you find the option to create smoothed polygon models for your pixel-based segmentations. It took a while to show results when using this feature for segmentations with many labels like the results of TotalSegmentator. Well, no more! The models are now generated in parallel for each label. In that regard, you are now also able to change the opacity of multiple data nodes at once, making the postprocessing of TotalSegmentator and alike for display blazingly fast.
DICOM Browser
The DICOM Browser allows users to locate and load DICOM images organized in a hierarchy of patients, studies, and series. It consists of three main components:
- Local Storage: Quickly access previously imported or retrieved DICOM images.
- Import: Scan directories to identify and manage DICOM images.
- Query/Retrieve: Connect to a PACS server to query and retrieve images.
The DICOM Browser is part of MITK since many years, but was significantly overhauled for MITK v2024.12. Give it a try to explore and import your DICOM data.
New command-line app to split 4-dimensional images
The new MitkSplit4Dto3DImages app allows you to easily split a 3d+t (4-d) image into its time steps as separate 3-d images.
News for developers
The following sections primarily address developers to summarize important or backward-incompatible changes since the last MITK release.
Migration from Phabricator to GitLab and GitHub
Since our last release, we migrated from Phabricator to GitLab for internal repository hosting and issue management. We still mirror MITK to our official GitHub page and in fact started to utilize more features of GitHub again like
issues for external reporters (including templates) and detailed release notes as well as changelogs on the releases page. In particular, our snapshot releases are now also listed on that page as pre-releases including downloads for the installers.
Reduced build times
We were able to greatly reduce the build time of MITK in particular on Windows with the combination of precompiled headers and using the Multi-ToolTask scheduler of Visual Studio.
🛠 Third-party dependency changes
The following table shows a complete list of changed third-party dependencies.
| Dependency | Old version | New version |
|---|---|---|
| v2.10.19 (patched) | ||
| CTK | 37aff992 (patched, 2023-12-15) |
adab52fb (patched, 2024-11-26) |
🔥 Disclaimer for API-breaking changes
We discontinued the extensive listing of API-breaking changes as the vast majority of them are straight forward to resolve or do not affect the majority of developers at all. The ratio between the time and effort spent for writing these reports and actual developer feedback turned out to be greatly imbalanced.
In case you experience any trouble while migrating to the latest version of MITK, please do not hesitate to create an issue on our GitHub page.

MITK v2024.06.2
Note
This is a hotfix release. The overview below is limited to the fixed issues since the original MITK v2024.06 release.
TotalSegmentator v2.2 installation
TotalSegmentator v2.2 fails to install since NumPy v2 is available. We fixed the NumPy dependency to v1 as countermeasure.
Packaging MITK on Windows with Qt v6.7
Qt changed the name of the Windows style plugin in Qt v6.7. MITK is using the new plugin name for packaging with Qt v6.7 and later now.
Typos
We fixed a few semicolons in the Segmentation Utilities GUI that were supposed to be colons.
MITK v2024.06
News for MITK Workbench users
We are proud to release MITK v2024.06, the most feature-heavy release in years! In the past 6 months we resolved about 230 tasks and issues in over 660 commits. We are already excited about your feedback on many improvements and features.
Customizable MITK Workbench
You are now optionally greeted by a dialog at application start to tailor the MITK Workbench to your specific needs.
Select from a few pre-defined plugin presets or easily define your own to only display the tools and plugins you actually need for your work.
Segmentation
MR image support with TotalSegmentator v2.2
The TotalSegmentator segmentation tool was updated to version 2.2 of TotalSegmentator. Besides the already supported 117 classes for CT images, 56 classes for MR images are now supported with the total_mr task. See the following official image from the TotalSegmentator GitHub page for an overview of all new MR image classes:
MedSAM
The new MedSAM AI-based 2-d segmentation tool is similar to the Segment Anything tool, but is explicitly tailored for medical images. Segmenting anatomical structures and pathologies with a few clicks is now easier than ever.
MONAI Label
We are excited to announce the introduction of the MONAI Label tool, developed focusing on inferencing capabilities. MITK now supports both automatic and click-based interaction mod 8000 es, allowing users to leverage the strengths of AI-driven segmentation in particular using the Radiology app.
Utilities
The Segmentation Utilities plugin supports multiple labels per image now in all of its tools like Boolean Operations, Morphological Operations, Image Masking, Image/Contour/Mesh-to-Segmentation conversion and the completely new Extract from Segmentation tool, which can be used to extract labels into separate binary images.
General improvements
- Labels can be easily identified in an instant now when hovering over them in the Segmentation plugin, since they are displayed highlighted in the image accordingly.
- While we support multiple labels in segmentation interpolation since MITK v2023.04, it is much more robust and reliable now.
- Many segmentation tools can be used more intuitively now and contribute to an overall improved user experience.
Statistics
The Statistics plugin supports multiple labels per image now and is performing faster than ever.
ModelFit and Perfusion
We are excited to announce the integration of ModelFit into the latest MITK release!
This new feature as part of the Workbench provides robust tools for model-fitting including an extensive framework for the specialized application of model-fitting in the area of dynamic contrast-enhanced MRI.
Please have a closer look at the key features here.
We also added the following command-line apps to our official installers:
- PixelDumpMiniApp: Dump (potentially masked) pixel values of passed images into a CSV file.
- Fuse3Dto4DImageMiniApp: Fuse several 3-d images with the same geometry into a dynamic 4-d (3d+t)
- GenericFittingMiniApp: Make a pixel-based fitting on the intensity signal over time for a given model function.
MxN image viewer
To simplify the comparison of images in the MxN view, we have added the option to set a "Data-Based Layout".
This allows users to select a set of images and automatically get a window layout containing all the view directions for each image.
The possible amount of windows is only limited by your imagination (and the size of your screen)!
News for developers
The following sections primarily address developers to summarize important or backward-incompatible changes since the last MITK release.
Qt 6
We finally switched from Qt 5 to Qt 6 (minimum v6.6.2).
The migration from Qt 5 to Qt 6 potentially has the biggest impact on your code since the last release. A lot of mainly minor adaptions were necessary on our side. We recommend to frequent the official Qt documentation and porting guide.
MITK-IGT
Just like MITK-Diffusion a few years ago, MITK-IGT followed to move into a separate MITK extension. MITK-IGT provides highly valuable and proven image-guided therapy functionality.
Improved integration of MITK extensions into the MITK superbuild
It is now possible to have (more) influence on MITK's third-party dependencies. Individual dependencies of MITK extensions can be optionally processed before MITK's own dependencies, allowing them to be used in MITK's dependencies. For example, if you add OpenCV to your MITK extension dependencies, you are now able to also activate the OpenCV bridge functionality of ITK, since it is configured and built after OpenCV.
MITK extensions also have improved documentation capabilities now, as you can customize Doxygen's EXAMPLE_PATH to provide your own examples.
Command-line apps moved into apps subfolder
For the sake of clarity we moved all command-line apps in our installers and packages from the top level into the apps subfolder. Please adapt your scripts and workflows accordingly.
Command-line argument style on Windows
On Windows, the MITK Workbench and alike exclusively used Windows-style command-line arguments like /BlueBerry.clean in the past. Please use Unix-style command-line arguments like --BlueBerry.clean from now on on all supported platforms.
🛠 Third-party dependency changes
The following table shows a complete list of changed third-party dependencies. The most notable change is the upgrade from Qt 5 to Qt 6 (minimum v6.6.2).
We recommend to use the Qt online installer to install the following required Qt 6 components:
- Qt 5 Compatibility Module
- Qt State Machines
- Qt WebEngine
On Windows, the Qt installer offers a welcome and straight forward way to install OpenSSL v3.x as well.
