MeVisLab is a development environment for medical image processing and visualisation, built by MeVis Medical Solutions and Fraunhofer MEVIS. You assemble processing networks by connecting modules on a canvas instead of writing a whole application. If you searched for a MeVisLab download, you are most likely a researcher, a student or a developer who needs to prototype an image-analysis workflow, for example on CBCT data.
It is not ready-made dental software. There is no official dental module, no patient management and no implant planner. MeVisLab is conditionally free: a free SDK with restrictions is available, and a professional edition exists for commercial work, so this page treats it as shareware (conditionally free).

What it does
- Lets you build image-processing and visualisation workflows by connecting modules in a graphical network editor.
- Lets developers add their own modules in C++, including modules based on ITK, Open Inventor and machine-learning code.
- Supports macro modules, which wrap a sub-network and its panel into one reusable block.
- Provides Python scripting inside the environment; the 4.2 release is based on Python 3.13 and Qt 6.9.
- Allows modules to be encrypted before you hand them to another user.
- Includes documentation, tutorials and release notes on the official site.
How dental teams use it
Dental use means research and development. A university group or a software team can use MeVisLab to explore a question on 3D dental data before building a final tool. The result is a prototype, not a cleared medical device.
Prototype a CBCT processing chain
- Load a 3D DICOM series with an import module.
- Connect filter and segmentation modules and watch each intermediate result in a viewer module.
- Save the network so a colleague can open it and reproduce the same steps.
Teach image processing
Students can see what each processing step does to a volume because every module has a visible input and output. This is easier to follow than reading code, and the free SDK is enough for small exercises.
Build a research viewer
A developer can wrap a network in a macro module with its own panel, so clinicians in a research study see only a few controls instead of the whole graph. Remember that results from the non-commercial SDK may not be used for commercial purposes.
Install and first run
- Open the download page on the official site and choose the installer for Windows or Linux.
- Run the installer. Without a licence file, the free SDK terms apply.
- Start MeVisLab and open one of the bundled example networks to learn how modules connect.
- For commercial work or to lift the limits, ask MeVis about the Professional SDK. The vendor also offers evaluation licences; check the current terms on the official site.
Limitations
- The free SDK allows at most five own or third-party modules to be instantiated at a time.
- Scripting in own and third-party modules is limited to 2 KB, and importing your own or third-party Python modules is not possible.
- Panels of own and third-party modules show a licence disclaimer.
- Results of the non-commercial SDK may not be used commercially, and redistributing the SDK itself is not permitted.
- It has a learning curve; it is a toolkit for developers, not a viewer you open and use in a minute.
- The official 4.2 announcement lists Windows and Linux; do not plan on macOS support.
MeVisLab vs alternatives
| Tool | Choose it when |
|---|---|
| MeVisLab | You want to prototype with ready modules in a visual network |
| MRIcroGL | You only need to view a volume in 3D and convert DICOM to NIfTI |
| ImageJ / Fiji | You need measurements and quick analysis with plugins |
| ITK and VTK | You prefer writing code against open-source libraries without licence limits on module count |
For a ready-to-use open-source medical viewer, medInria is another option on this site.
FAQ
Is MeVisLab free?
Partly. A free SDK is available without a licence file, with the restrictions listed above and for non-commercial institutions only. Commercial use needs the Professional SDK.
Where is the MeVisLab download?
On the download page of the official site, mevislab.de. Check the licence terms before you install.
Is there MeVisLab for Mac?
The official 4.2 release announcement lists Windows and Linux builds only. Check the download page for the current platform list before planning a Mac setup.
What is the MeVisLab licence?
Licences are issued per named person. The free SDK is for non-commercial institutions; the Professional SDK is for companies and commercial goals.
Can MeVisLab do segmentation?
Yes, it is used to build segmentation workflows from modules or custom code. It does not ship a ready dental segmentation tool.
Is there a MeVisLab tutorial?
Yes. The official site offers documentation and getting-started tutorials that explain networks, modules and macros.
Is MeVisLab on GitHub?
The vendor distributes the SDK through its own download page on mevislab.de, so use that rather than a third-party copy.
Can I use MeVisLab output for patient care?
MeVisLab is a development platform, not a cleared diagnostic product. Any clinical tool built with it must go through its own regulatory process.
Last checked against official sources: 9 October 2026 (developer website: mevislab.de). Versions and licence terms change — confirm on the developer's site before deploying in a clinic.
