Introduction

Orthanc provides support for whole-slide imaging (digital pathology). The implementation is made of three components:

A command-line tool called "Dicomizer" that converts whole-slide images to DICOM, following Supplement 145. This conversion tool can take advantage of the well-known OpenSlide toolkit to decode the proprietary file formats that are commonly used in digital pathology. An Orthanc plugin that extends Orthanc Explorer with a Web viewer of whole-slide images. This plugin is based upon OpenLayers, a JavaScript framework to display dynamic maps in any web page. A command-line tool called "DicomToTiff" that converts some whole-slide image stored in an Orthanc server, into a standard hierarchical TIFF image. This tool can be used to export DICOM images to any post-processing framework.
