Did you know that Orthanc is a component of MSF's (Médecins Sans Frontières) on-site infrastructure? It runs inside their Field Network Kits (FNKs) to manage X-ray imagery. Check out this great presentation at FOSDEM! https://fosdem.org/2025/schedule/event/fosdem-2025-5165-nixos-doctors-without-borders-msf-why-we-use-it-and-how/

J'ai eu l'honneur d'être interviewé pour la capsule "Un œil sur demain" du journal télévisé de la RTBF, afin d'évoquer l'intelligence artificielle en imagerie médicale. #UCLouvain

The OHIF and Kitware's VolView plugins for Orthanc have been updated to OHIF 3.9.2 and VolView 4.3.0. These updates enhance the capability to efficiently explore imaging data, leveraging Orthanc’s integration features to support advanced medical image visualization.

They say you should never release on Fridays, especially not before holidays. Anyway, the new release 3.0 of the whole-slide imaging plugin is now available!

This release brings support for on-the-fly generation of multi-resolution pyramids directly from DICOM instances. This new feature enables efficient viewing of high-resolution images directly in a Web browser (such as a mammogram), without downloading the full image locally or generating a separate series using the OrthancWSIDicomizer command-line tool. Compatibility with IIIF is provided as well.

A very joyful holiday season to all of you,
Sébastien-

Notre collaboration explore l'applicabilité d'Orthanc comme serveur multimédia pour le partage des numérisations des collections anthropologiques grâce au standard d'interopérabilité DICOM.

Ce travail vient d'être présenté au 35e édition du Colloque du Groupement des Anthropologistes de Langue Française (GALF 2024).

Version 2.1 of the whole-slide imaging plugin for Orthanc has just been released!

This new release brings a huge number of improvements, including better support for the Leica (.scn), Mirax (.mrxs), and Hamamatsu (.ndpi) formats, as well as for sparse tiling.

In addition, the "--padding" option of the OrthancWSIDicomizer command-line tool offers an easy way to pad JPEG, PNG, and plain TIFF images with a border to make their size compatible with deep zoom over the IIIF protocol.

Happy twelfth birthday, Orthanc!

I am pleased to announce the release of version 1.2 of the #DICOM #STL plugin for Orthanc.

This release upgrades the embedded Nexus viewer for cultural heritage to version 2.3. It also brings support for the #3DHOP viewer.

The first release of the #Java plugin for Orthanc is available! This plugin enables Orthanc to execute code written in Java. This can notably be used to combine Orthanc with the dcm4che library for #DICOM, or to turn Orthanc into a #FHIR server using HAPI. https://discourse.orthanc-server.org/t/java-plugin-for-orthanc-1-0/4812

Introducing our latest plugin for Orthanc! Now you can encapsulate #STL files into #DICOM instances seamlessly, then display them using any Web viewer. STL files can also be automatically generated from DICOM structure sets (RT-STRUCT). https://orthanc.uclouvain.be/book/plugins/stl.html

Yet another scientific publication that talks about Orthanc without citing the associated paper. Such a behavior hinders the search for funding to pursue the development of free and open-source projects for the benefit of the whole community.
