Due to the launch of the new dynamic medical FLOSS project listing/portal at www.medfloss.org, this page here will not be updated anymore.
https://apfelkraut.org/freemedsw, last updated: 19. January 2010.
Major updates of this overview or related news will be announced on my blog under category Open Source .
This link collection should provide an overview of Open Source software for the health care sector.
My understanding of Open Source is like it is defined by the Open Source Initiative (OSI) in „The Open Source Definition“. To the best of my knowledge I included only projects that are conform to this definition. Most of them are published under one of the popular open source licenses like GPL, LGPL, MPL or the Apache license (Overview of open source licenses by the OSI).
Furthermore only active projects are included (last news or releases not older than a year).
I do not provide any guarantee for the correctness of the here listed information. I would greatly appreciate it if you could leave a comment or send me a message in case of a broken link, incorrect information or improvement suggestion(s).
- You can submit new projects here.
As this is at the moment only a static page, I cannot assign a project to different categories. So I listed them under the category to which they fit most. For example: practice/hospital management systems normally offer also features to create a EMR, but their primary purpose is to support the users in managing their practice/hospital.
- Clinical Research
- DICOM Tool(kit)
- DICOM Viewer/Server
- Disaster/Disease Management
- Electronic Medical Record
- HL7 Tool(kit)
- Hospital Management
- Integration Tool(kit) / Middleware
- Practice Management
- Signal Processing
- Veterinary Medicine
- Linux Distribution
There are other similar listings to which I referred to while creating this one. For details please see Further Sources at the end of this page.
Project attributes are listed in the following way:
<project name> [<used license> | <platform> | <client type>] – <project description>
<platform>: Lists all platforms on which the application can be installed and executed. In case of a client-server system that offers web-based access, this represents just the supported platform(s) for the server.

It is intended to serve not only for the classification of surgical procedures but also for a wide variety of other applications – electronic healthcare records (EHCRs), clinical user interfaces, decision support systems, knowledge access systems, and natural language processing. The ontology is constructed according to carefully selected principles so that the reasons for classification are always explicit within the model and therefore available for processing and analysis by each application. This leads to an ontology in which most information lies in the descriptions and definitions. The hierarchies are built bottom-up automatically based on these definitions. The GALEN CORE Model can be browsed via the OpenGALEN Browser.
