As the leader of a free and open-source community, it is always a great feeling to discover that some large-scale company uses your project inside their products. Today, a job offer indicates that Orthanc is used by Topcon Health in the context of eye imaging.
Besides this specific example, it would be so nice if such companies could learn to proactively propose their support to the maintainers of the free and open-source projects they use, for instance by establishing win-win research projects, so as to nurture the upstream work.
