Free Radiology Software - PACS, RIS, DICOM
Used PACS Equipment - why buy new when you can get used radiology equipment at a fraction of the cost.
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.

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. The DICOM viewer 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.
ImageMagick - (Windows, OS2, Linux and Unix) a robust collection of tools and libraries to read, write, and manipulate an image in many image formats (over 90 major formats) including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick you can create images dynamically, making it suitable for Web applications. You can also resize, rotate, sharpen, color reduce, or add special effects to an image or image sequence and save your completed work in the same or differing image format. Image processing operations are available from the command line, or from the C, C++, Perl, Java, PHP, Python, or Ruby programming languages. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. ImageMagick's focus is on performance, minimizing bugs, and providing stable APIs and ABIs.
iRad - (Macintosh) Dicom viewer specifically developed for the Mac os.
ImageJ - (Web Based, Macintosh, Windows and Unix) - ImageJ is a public domain Java image processing program. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine.
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.
Medcon and XMedcon - (DOS, Windows and Unix) Some PR-talk here. The project stands for Medical Image Conversion. Released under the (L) GPL licence, it comes with the full C-source code of the library, a flexible command-line utility and a neat graphical front-end using the Gtk+ toolkit. The supported formats are: Acr/Nema 2.0, Analyze (SPM), Concorde/µPET, DICOM 3.0, CTI ECAT 6/7, InterFile3.3 and PNG or Gif87a/89a. The program also allows to read unsupported files without compression, to print pixel values or to extract/reorder specified images. It is possible to retrieve the raw binary/ascii image arrays and to write PNG or annimated GIF for desktop applications. The library could be used as a framework for your own image formats. Using the GNU 's autoconf tool, make utility & C compiler, the code has been successfully build on a variety of systems.
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 my freeware 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.
Papyrus - (Macintosh, Windows and Unix) The Papyrus toolkit 3 is a library of C routines that greatly eases the process of reading and writting DICOM, DICOMDIR and Papyrus files. It is available for the Windows, Macintosh and Unix plateforms. The Papyrus toolkit 3 conforms to part 10 of the DICOM standard build by the ACR/NEMA which is the actual standard for digital imaging in radiology. The Papyrus toolkit 3 is OSI Certified Open Source Software. OSI Certified is a certification mark of the Open Source Initiative. The Papyrus toolkit 3 is now distributed in Open Source mode under the GNU Lesser General Public License (usually known as LGPL). This way you are free to download the Papyrus toolkit 3 and to use it for your developements.
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.
