Orthanc

 A Brief History of Orthanc and Its Maintainers :

Orthanc in 2025 :
Sébastien continues to develop Orthanc for research and teaching at UCLouvain, aligning with the project’s mission: “Share technical knowledge about medical imaging.” 
Orthanc Team focuses on supporting the community—software vendors, small PACS users, and clinics—ensuring Orthanc remains accessible and reliable. 

Funding the Future
Donations on Open Collective help sustain Orthanc’s development. For three years, we’ve relied on contributions averaging €4,000/month, with 75% from a single donor who recently ended their support. To ensure Orthanc’s future, we’re calling on the community to diversify and expand our funding base.

How You Can Help
 

Your contribution ensures Orthanc remains free, open, and community-driven.  Donations support the project’s sustainability but do not include custom development or exclusive features. For dedicated support or specific features, reach out to professional providers.

Thank You
Orthanc thrives because of its community. Whether you’re a user, developer, or advocate, your support - financial or otherwise - makes a difference. Together, we can keep Orthanc strong and accessible for years to come. 

With gratitude
