About



First a very quick history of Orthanc and its maintainers:
  • 2011 : Sébastien Jodogne created and developed Orthanc alone while working at the University Hospital of Liège – Belgium (CHUL).
  • 2015 : Together with myself (Alain Mazy) and other stakeholders, Sébastien founded Osimis to provide professional services around or on top of Orthanc, as well as to propose certified products that can be deployed within US/EU hospitals.
  • 2021 : Both Sébastien and I left the Osimis management team. Sébastien became professor at University of Louvain – Belgium (UCLouvain) and I went back to freelancing as a Software Developer.

The situation in February 2022 is as follows:
  • Osimis has decided to reduce its support to Orthanc development and focus on AI integration.  Therefore, I’m willing to find a new sustainability model for the Orthanc eco-system.
  • Sébastien continues to develop Orthanc for research and teaching purposes as part of his work at the University, and to maintain the project according to the mission statement of the Orthanc project: “Share technical knowledge about medical imaging.”
  • I will maintain Orthanc with a focus on general community users like software vendors integrating Orthanc in their apps or users running Orthanc as a small PACS.
  • Osimis is still providing the build/hosting infrastructure for the Orthanc project and is funding me a few days a month to keep the project active from an industrial point of view.
  • The Orthanc IP belongs to CHUL – Osimis – UCLouvain and this will remain.  Although this hinders accepting external contributions, this situation is currently fine for the maintainers. Should the project sustainability require it, the maintainers would have the opportunity to fork the project to make sure it keeps going forward. A fork is annoying for everyone, users and maintainers, so it is best to stay away from it.

Unfortunately, with only a few days funded each month, I do not have enough time to create real new features in Orthanc or to effectively maintain it.

Therefore, I am calling for the community to help fund the Orthanc project and mutualize the development cost between as many backers/sponsors/donators as possible.

If you are a Medical Doctor using Orthanc in your daily activity or a freelancer providing Orthanc support, remember that you have paid for your desk or your printer but, so far, you have probably not paid anything for Orthanc. If you think Orthanc is as important to your business as your desk or your printer, then feel free to become a backer of the Orthanc project on Open Collective.

If you are a small clinic using Orthanc in your daily activity, a software company that is integrating Orthanc in its solution, remember that you have paid for your X-Ray, office coffee machine or cloud infrastructure but, so far, you have probably not paid anything for Orthanc. If you think Orthanc is as important to your business as your X-Ray, your office coffee machine or your cloud infrastructure then feel free to become a sponsor of the Orthanc project on Open Collective.

My first goal in funding is to reach 5.600 EUR a month in order to pay 80h a month to maintainers so as to get back to more regular bug fixes, new features, and community support!

Note that, when contributing financially to a free and open-source project, you are not hiring the maintainers for your own needs. You are invited to suggest new features and request bug fixes, but the maintainers are driving the development and roadmap, trying to accommodate the needs of the whole community. 

Thanks a lot for your support.

Alain
