Welcome to the GNU Health/Orthanc conference!

OrthancCon 2023 will be the third edition of the international conference about Orthanc. It will explore the field of free, libre and open-source software for medical imaging. Participants will have the opportunity to network with the core developers of Orthanc, as well as with Orthanc community members from all around the world!

The conference is a joint organization with GNU Health Con 2023, the annual conference that brings together enthusiasts and developers of GNU Health, the acclaimed health and hospital information system.

All the talks will be in English. We also ask the attendance to carefully follow our code of conduct.

Call for presentations

Participants are invited to present their work about the following topics of interest:

  • Orthanc-specific contributions:
    • Real-world deployments of Orthanc (clinical departments, hospitals, regional/country-wide implementations,...).
    • Scientific projects that leverage Orthanc.
    • Industrial applications built using Orthanc.
    • Extensions to Orthanc (scripts, plugins,...).
  • Contributions beyond Orthanc:
    • Free, libre and open-source software (FLOSS), as well as open hardware projects, for medical imaging and digital pathology.
    • FLOSS for the automated analysis of medical images (computer vision, deep learning, and machine learning).
    • Healthcare interoperability through FLOSS and open standards (DICOM, BIDS, NIfTI, IIIF, FHIR,...).

Here are the presentation submission guidelines:

  • Deadline: September 6th, 2023.
  • Format: The submission must be provided as a plain text file (i.e. no formatted file format), must be written in English, and must include:
    • The title of your contribution.
    • The list of authors, with e-mails and affiliations.
    • The abstract (between 1000 and 1500 characters).
    • The bibliography (ideally with DOI, or hyperlinks).
    • The short biography of the presenting author (up to 500 characters, including spaces).
    • If your contribution is related to emerging economies, make sure to put emphasis on the benefits of your work in developing countries. This could lead to the inclusion of your work in the International Workshop on eHealth in Emerging Economies (IWEEE) that will take place on the first day of the conference.
    • Whether you want to give a talk or to present a poster. The poster size should be standard A0 format (84cm x 119cm).
  • If applicable, it is highly recommended to also provide up to 2 figures that illustrate your submission, in complement to the plain text file. These figures must be in PNG format with a minimal resolution of 1600x1200 pixels.
  • Type of talk: Two types of talk are possible, and you must specify which one applies to your submission:
    • On-site talk: This is the preferred type of talk.
    • Pre-recorded talk: If you cannot attend the conference on site in Hanover, you must submit a pre-recorded video of your talk of 10-20 minutes, encoded under the MP4 file format, together your the main text file describing your submission. A video-conference and a live Q&A session will be organized with the remote speakers, with the pre-recorded video serving as a fallback in the case of a bad Internet connectivity.
  • Submission: Please send an email to Sébastien Jodogne.
  • Proceedings: The audience of OrthancCon will receive an electronic copy of a booklet containing all the accepted abstracts.
