The Orthanc ecosystem for medical imaging

This paper reviews the components of Orthanc, a free and open-source, highly versatile ecosystem for medical imaging. At the core of the Orthanc ecosystem, the Orthanc server is a lightweight vendor neutral archive that provides PACS managers with a powerful environment to automate and optimize the imaging flows that are very specific to each hospital. The Orthanc server can be extended with plugins that provide solutions for teleradiology, digital pathology, or enterprise-ready databases.

On the use of WebAssembly for rendering and segmenting medical images

Rendering medical images is a critical step in a variety of medical applications, from diagnosis to therapy. In this paper, we show how the emerging WebAssembly standard can be used to share the same code base between heavyweight viewers and zero-footprint viewers. Moreover, we introduce a fully functional Web viewer that is entirely developed using WebAssembly and that can be used in research projects or in teleradiology applications. Finally, we demonstrate that deep convolutional neural networks for image segmentation can be executed entirely inside a Web browser thanks to WebAssembly.

Open implementation of DICOM for whole-slide microscopic imaging

This paper introduces an open implementation of DICOM for whole-slide microscopic imaging, following Supplement 145 of the DICOM standard. The software is divided into two parts: (a) a command-line tool to convert an whole-slide image to the DICOM format, and (b) a zero-footprint Web interface to display such DICOM images. The software architecture leverages the DICOM server Orthanc. The entire framework is available as free and open-source software. The existence of this software supports the development of digital pathology and telepathology in clinical environments, featuring a smooth integration with existing EHR and PACS solutions.
