Welcome to the Orthanc conference!

OrthancCon 2019 will be the first edition of the international conference about Orthanc, and will explore the field of free, libre and open-source software for medical imaging. The conference will take place in December 2019 in Liège (Belgium), the city where Orthanc was born. This will be the ideal place to meet the whole community of users and developers of Orthanc!

Besides medical imaging, the conference will also promote free, libre and open-source software for healthcare. To this end, OrthancCon 2019 will be a joint organization with our friends from GNUHealthCon 2019, the annual conference that brings together enthusiasts and developers of GNU Health, the acclaimed health and hospital information system.

OrthancCon 2019 will notably feature:

  • Talks from free software projects in healthcare and medical imaging.
  • Real-world deployments of Orthanc, and applications built using Orthanc.
  • Tutorials and hands-on sessions about DICOM and medical imaging.
  • The presence of the developers of Orthanc and of its commercial partner Osimis.
  • The official release of the Stone of Orthanc, our next-generation free toolkit for rendering medical images.


OrthancCon will take place in the GIGA tower (B34), on the beautiful site of the University Hospital of Liège, where the Orthanc project was conceived!

University Hospital of Liège

The hospital is located in the exceptional campus of the Sart-Tilman, roughly ten kilometers South of Liège city center, over several hundred hectares of lushy green space and forest. By choosing this great location at the interface between a university, a hospital and a science park, we want to stress the fact that social medicine is a highly interdisciplinary field.

Liège center offers a large choice of hotels for any budget. The hospital can be reached by public transportation, notably using the TEC bus lines 48 and 58 (about 30 minutes per trip). As an alternative location, if you don't mind missing the festive, fervent spirit of Liège, Boncelles city offers some hotels and is located closer to the hospital (about 1,5km of walk). Note that Belgian beers can be found both in Liège and in Boncelles!


Here is the early program of the conference:

  • Friday 13th, December: Plenary sessions dedicated to free software in healthcare, gathering the Orthanc and GNU Health communities:
    • Friday AM: XII International Workshop on eHealth in Emerging Economies (IWEEE).

    • Real-world deployments and applications of Orthanc.
    • Free training sessions about DICOM using free software.
  • Saturday 14th evening: Joint social event courtesy of Osimis, featuring the yearly GNU Health Social Medicine awards ceremony.

This is tentative schedule: Full program of the conference will be made available as soon as possible.

The talks will all be in English. We also ask the attendance to carefully follow the GNU Health code of conduct.
