DICOM image viewers

Last update : May 30, 2016

Referring to my recent post about the DICOM standard, this contribution presents an overview about an important entity in the medical imaging workflow : DICOM image viewers. The list is not exhaustive; I did the following segmentation to present my personal selection of current DICOM image viewers :

  1. Reference viewer
  2. Reference toolkits
  3. Open source viewers
  4. Free proprietary viewers
  5. Licensed commercial viewers
  6. Mobile viewer apps
  7. Other viewers

1. Reference DICOM Viewer

Today one project is generally considered as a reference for DICOM applications : OsiriX.


The OsiriX project started in November 2003. The first version was developed by Antoine Rosset, a radiologist from Geneva, Switzerland, working now at the La Tour Hospital  in Geneva. He received a grant from the Swiss National Fund to spend one year in UCLA, Los Angeles, with Prof. Osman Ratib, to explore and learn about medical digital imaging. In October 2004, Antoine Rosset went back to the Geneva University Hospital in Switzerland, to continue his career as a radiologist, where he published an OsiriX reference article in June 2004 in the Journal of Digital Imaging. Joris Heuberger, a mathematician from Geneva, joined the project in March 2005 on a voluntary fellowship of 6 months in UCLA, Los Angeles. In June 2005, OsiriX received two prestigious Apple Design Awards : Best Use of Open Source and Best Mac OS X Scientific Computing Solution. Osman Ratib, Professor of Radiology in UCLA, returned to Geneva at the end of 2005 as the chairman of the Nuclear Medicine service.

In March 2009, Antoine Rosset, Joris Heuberger and Osman Ratib created the OsiriX Foundation to promote open-source in medicine. In February 2010, Antoine Rosset and Joris Heuberger created the company Pixmeo to promote and distribute the OsiriX MD version, certified for medical imaging. This version complies with the European Directive 93/42/EEC concerning medical devices. The price for a single licence is 678 EUR. The free lite version can be downloaded from the OsiriX website, the source code is available at Github.

OsiriX runs on Mac OSX and is released under the version 3 of the GNU Lesser General Public License. The current version is 7.0 and was released on December 7, 2015. Osirix can also be configured as a PACS server. The power of OsiriX can be extended with plugins.

An Osirix HD version for the iPad is available at the AppStore for 49,99 EUR.

2. Reference DICOM toolkits

DICOM toolkits are more than simple viewers; they are a complete set of tools, code samples, examples, documentation, tutorials etc to develop great healthcare applications.


DCMTK is a collection of libraries and applications implementing large parts the DICOM standard. It includes software for examining, constructing and converting DICOM image files, handling offline media, sending and receiving images over a network connection, as well as demonstrative image storage and worklist servers. DCMTK is is written in a mixture of ANSI C and C++. It comes in complete source code and is made available as open source software.

DCMTK is an ancestor of DICOM applications. In 1993, before the official release of the standard, a DICOM prototype implementation was created by OFFIS, the University of Oldenburg and the CERIUM (Centre Européen d’Imagerie à Usage Médical) research centre in Rennes (France) on behalf of the European Committee for Standardization (CEN/TC251/WG4).

The current version of DCMTK is 3.6.1, released in June 2015. The related snapshot is available at the dicom.offis.de website. DICOMscope is the related free DICOM viewer which can display uncompressed, monochrome DICOM images from all modalities and which supports monitor calibration according to DICOM part 14 as well as presentation states. DICOMScope 3.6.0 for Windows, implemented in a mixture of Java and C++, was released in 2003. DICOMscope can’t be installed on newer Windows systems (Vista, Windows 7, Windows 8.1), an error 105 (setup.lid missing) is issued.


DICOMscope version 3.5.1 (archive image)

Some DCMTK modules, especially those that are not part of the free toolkit, are covered by a separate license which can be found in the COPYRIGHT file in the corresponding module directory. These tools can be evaluated during a period of four months, any further use of the software requires a full licence agreement, free of charge.

The following sub-packages are part of DCMTK :

  • config: configuration utilities for dcmtk
  • dcmdata: a data encoding/decoding library and utility apps
  • dcmimage: adds support for color images to dcmimgle
  • dcmimgle: an image processing library and utility apps
  • dcmjpeg: a compression/decompression library and utility apps
  • dcmjpls: a compression/decompression library and utility apps
  • dcmnet: a networking library and utility apps
  • dcmpstat: a presentation state library and utility apps
  • dcmrt: a radiation therapy library and utility apps
  • dcmsign: a digital signature library and utility apps
  • dcmsr: a structured report library and utility apps
  • dcmtls: security extensions for the network library
  • dcmwlm: a modality worklist database server
  • dcmqrdb: an image database server
  • oflog: a logging library based on log4cplus
  • ofstd: a library of general purpose classes

Each sub-package (module) contains a collection of sub-modules (functions). For example, the networking library dcmnet contains the following command line tools :

  • dcmrecv: Simple DICOM storage SCP (receiver)
  • dcmsend: Simple DICOM storage SCU (sender)
  • echoscu: DICOM verification (C-ECHO) SCU
  • findscu: DICOM query (C-FIND) SCU
  • getscu: DICOM retrieve (C-GET) SCU
  • movescu: DICOM retrieve (C-MOVE) SCU
  • storescp: DICOM storage (C-STORE) SCP
  • storescu: DICOM storage (C-STORE) SCU
  • termscu: DICOM termination SCU


dcm4che2 is a collection of open source applications and utilities for the healthcare enterprise developed in the Java programming language. dcm4chee2 is a DICOM Clinical Data Manager system.

dcm4che2 contains a number of useful sample applications that may be used in conjunction with dcm4chee, with another archive application, or to operate on DICOM objects in a standalone fashion. A list of the dcm4che2 utilities is shown hereafter :

  • dcm2txt- Convert a DICOM object to text
  • dcm2xml- Convert a DICOM object to XML
  • dcmdir- Manipulate a DICOM dir
  • dcmecho – Initiate a C-ECHO command as an SCU
  • cmgpwl – Query a General Purpose Worklist SCP
  • dcmmwl – Query a Modality Worklist SCP
  • dcmof – Simulate an Order Filler application
  • dcmqr – Perform C-FIND, C-GET and C-MOVE operations as an SCU
  • dcmrcv – DICOM receiver (C-STORE SCP)
  • dcmsnd – Perform C-STORE operations as an SCU
  • dcmups – Unified Worklist and Procedure Step SCU
  • dcmwado – Initiate DICOM WADO requests
  • jpg2dcm – Convert a JPEG image to DICOM
  • logger – Log files to a Syslog destination
  • mkelmdic – Create the serialized dcm4che2 DICOM Dictionary
  • mkuiddic – Create the dcm4che2 UID dictionary

  • pdf2dcm – Convert a PDF document to DICOM
  • rgb2ybr – Convert pixel data from YBR to RGB format
  • txt2dcmsr – Convert text to a DICOM Structured Report
  • xml2dcm – Convert XML to DICOM

The dcm4che history states that back around the year 2000, Gunter Zeilinger wrote the popular JDicom utility suite using commercial Java DICOM Toolkit (JDT). After this experience, he decided to develop his own toolkit and to name it after Che Guevara.
dcm4che and dcm4chee are licensed under an MPL/GPL/LGPL triple license, similar to Mozilla.
