Free DICOM Viewers

AccuLite  — (Windows) Free DICOM viewer and basic browser for DICOM datasets. This can be used to create auto-run CDs of DICOM studies that will run on most modern PCs.

MicroDicom — MicroDicom is application for primary processing and preservation of medical images in DICOM format. It is equipped with most common tools for manipulation of DICOM images and it has an intuitive user interface. It also has the advantage of being free for use and accessible to everyone.

Sante — (Windows) Views DICOM files on a low cost PC. It supports a large number of DICOM implementations.

AMIDE — (DOS, Macintosh, Windows and Unix) Free tool for viewing, analyzing, and registering volumetric medical imaging data sets. It's been developed using GTK+/GNOME, and runs on any system that supports the toolkit.

Dicom2 — (Windows and Unix) a free command-line driven program which allows you to convert medical images and DICOM files to various other formats, while optionally performing some rudimentary image processing tasks.

Dicom3Tools — Tools and libraries for handling offline files of DICOM 3 attributes, and conversion of proprietary formats to DICOM 3. Can handle older ACR/NEMA format data, and some proprietary versions of that such as SPI.

DICOM Works — (Windows) Free PC based DICOM viewer and converter with many options and features.

Dr Razz — (Macintosh) Dr Razz is a 16 bit image display and analysis program for Macintosh color computers. The program has been optimized for display of radiographic CT and MRI images, although any 16 bit image stored in a raster file format (with or without a header) can in principle be viewed. Features include near real-time window width and window level adjustments on the full 16 bit image data on standard Macintosh graphic hardware. Images can be viewed individually, or a series of images (eg, a CT or MRI exam) can be viewed in an image stack. Most non-compressed CT and MRI images can be opened automatically, without entering any image parameters. In the 'Auto' open mode, the program attempts to automatically determine image type (CT vs. MRI), presence of a header and byte order (little endian vs. big endian). However, a 'Custom' open mode allows complete adjustment of these and other parameters. Images created with the General Electric 'ximg' image extraction tool can be opened directly, even if compressed. The window width and window level setting can be interactively changed via the window/level control, or by the arrow keys.

Universal PACS — (Windows) UniPACS DICOM Viewer is a small and free subset of the UniPACS Viewing Workstation. It will allow you to open DICOM files, analyze them with the most common tools (window/level, zoom, etc.), save DICOM images into BMP, PGM, JPEG or Power Point files, and anonymize your DICOM data. It will allow you to open DICOM files, analyze them with the most common tools (window/level, zoom, etc.), save DICOM images into BMP, PGM, JPEG or Power Point files, and anonymize your DICOM data.

eViewbox — (Web Based, Macintosh and Windows) Eviewbox, is an open source radiology project. This application allows to view many kind of images, including DICOM. When images are all the same size it allows for multiplanar reconstruction. The corresponding EViewBox applet allows for a multiplatform distribution of medical images. The application footprint is under 120 K and can be sent with the images.

ezDICOM — (Windows) This software is designed to display most medical images: MRI, CT, X-ray, and ultrasound. All versions of ezDICOM can automatically detect and open Analyze, DICOM, Genesis, Interfile, Magnetom, Somatom and NEMA images.

FP Image — (Windows) View and process floating point and integer images. Reads proprietary formats, and is a powerful image processor scripting language 3D rendering engine.

iRad — (Macintosh) Dicom viewer specifically developed for the Mac os.

IDICON — (DOS and Unix) A software package which includes tools for automatic conversion between the medical image formats Interfile 3.3 and DICOM 3.0, and for manipulating files in DICOM 3.0 format.

Irfanview — (Windows) Fast and compact tool that can batch convert DICOM images to JPEG, GIF, PNG, TIF or other common computer graphic formats.

JAVA Viewer — (Web Based) This DICOM Viewer allows DICOM images to be manipulated and displayed efficiently by using the general-purpose WWW browser such as Internet Explorer, Netscape Navigator, and so on.

Madena — (Macintosh) Madena is a medical image viewer and image processing tool. Madena can open all QuickTime compatible image file formats as well as import most Digital Imaging and Communications in Medicine and ACR/NEMA file formats. DICOM is the current industry standard for medical images and is widely used for CT, MR and US images. Madena can open both individual image files or all image files found within a folder and (optionally) all enclosed subfolders in a single command. DICOM images are automatically organized into viewing and processing subsets according to their study and series tags. Quicktime images are grouped into subsets according to the folder in which they were found.

MRIcro — (Windows and Unix) is a free DICOM Viewer for Windows and Linux. MRIcro can view Analyze, DICOM, ECAT, Genesis, Interfile, Magnetom, Somatom and NEMA images and convert them to the popular Analyze format.

MyPACS: Teaching File Authoring System — Free web application allows radiologists to create their own online teaching file repositories by uploading medical images through their web browser.

Offis — (Macintosh, Windows and Unix) Multiple software tools for viewing and manipulating DICOM and other medical image formats.

Rubo Medical Imaging — (Windows) Capable of handling all Dicom files of any modality (X-Ray angiogram, ultrasound, CT, MRI, Nuclear etc.), compression (lossless and lossy Jpeg, RLE), depth or color. Demo version - some functions disabled.

XNView — (Windows and Unix) This site features numerous free radiology image viewing and manipulation tools.
