Whole-Slide Imaging

October 22nd, 2016

The Orthanc project is delighted to announce that it now provides a reference, lightweight implementation of DICOM for whole-slide microscopic imaging (digital pathology).

Our implementation is made of three components: A command-line tool to convert digital pathology images into DICOM, an Orthanc plugin to display such images, and a command-line tool to export DICOM whole-slide images as standard hierarchical TIFF images.

To the best of our knowledge, this is the first free and open-source implementation of DICOM for whole-slide imaging. Check out the dedicated section about digital pathology on our homepage for more information!

Stone of Orthanc

October 14th, 2016

A new companion tool to Orthanc has just been released! This free and open-source tool is called the Stone of Orthanc. Just like a palantír, Stone is a means of seeing medical images in Orthanc servers.

More precisely, Stone of Orthanc is a lightweight, cross-platform C++ toolkit for the CPU-based rendering of medical images. It notably features support for MPR (multiplanar reconstruction of volume images), PET-CT fusion, and accurate physical world coordinates. Stone of Orthanc is similar in spirit to two other well-known toolkits:

  • Cornerstone by Chris Hafey, a client-side JavaScript toolkit to display medical images in Web browsers. However, contrarily to Cornerstone, Stone of Orthanc is written in C++, and can be embedded into native, heavyweight applications.
  • VTK by Kitware, a C++ toolkit for scientific visualization. However, contrarily to VTK that relies on graphics processing units (GPU), Stone of Orthanc is entirely focused on software-based rendering. Within Stone, 3D volumes are handled as sets of 2D slices.

Check out the dedicated section about Stone on our homepage for more information! We hope this new tool will contribute to the development of new, innovative, free and open-source applications for the viewing and analysis of medical images.

Enjoy,

Survey: Who Uses Orthanc?

July 31st, 2015

The Orthanc project is continuously growing. To support its development, we would love to hear which hospitals, universities, companies and organizations take advantage of Orthanc. Please let us know by sending a short mail!

To put weight on future grant applications for travels/hardware/servers/..., we wish to gather a list of institutions that use Orthanc for production, for quality assurance, or for R&D purpose. These institutions will be publicly listed on this Web site, in a separate "Orthanc Users" section.

If you wish to support Orthanc, please use the following pre-filled mail, ideally attaching your institution's official logo:
