Most of the available commercial software for manipulation of DICOM images is expensive by itself or distributed with expensive medical machinery. Free software packages on the other side are often non-intuitive and with limited functionality. There is a common situation for the user when more than one package is needed to achieve feasible results. The subject of the presented work is the design and implementation of a software package aimed to overcome the problem stated above. MicroDicom DICOM Viewer 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. Features: - Open and save medical images in DICOM format - Read DICOM files of any manufacturer and modality - Supported DICOM images - without compression and RLE, JPEG Lossy, JPEG Lossless, JPEG 2000 Lossy, JPEG2000 Lossless compressions - Structured Reports - MPEG-2 and MPEG-4 transfer syntaxes - Encapsulated PDF - Open DICOM directory files - Display patient list from DICOMDIR - Load via drag & drop or double-click - Open images in common graphic formats (JPEG, BMP, PNG, GIF, TIFF) - Convert DICOM images to JPEG, BMP, PNG, GIF, TIFF - Convert DICOM images to movie file format(AVI, WMV and MP4) - Copy DICOM image to clipboard - Anonymize DICOM images - Image orientation in overlay - Mouse-driven level-window, user-defined window presets - Zooming and panning - Medical image processing operation - Measurements and annotations - Brightness/contrast control - Image resize, Rotate, Flip, Invert - Displaying DICOM attributes of selected image - Suited for patient CD/DVD to show DICOM images without installation - Run on Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10 and Windows 11 - Available for x86 and x64 platforms - Portable version - And much more
What's new in 2026.4
- New features: 3D volume rendering is no longer experimental, with faster and smoother rendering and lower memory use. Added a 3D view toolbar; windowing, show/hide overlay, copy to clipboard and export to picture now work in the 3D view. Added new and improved 3D presets for CT and MR (Angio, Airways, Soft Tissue, MR Angio, Color) and custom presets. Added automatic hiding of the CT table in the 3D view. Added a Scalpel, a clipping box and Keep/Remove Connected Structure for cutting the 3D volume, with undo and redo. Added measurements and text annotations in the 3D view. Added 3D snapshots (camera, preset, window and cuts), which can be saved to and loaded from files. Added export of the 3D model to STL. Added export of 3D movies to MP4. 3D MPR and the 3D view now work together in a 2x2 layout, linked by the 3D cursor, with an option to show the MPR planes on the volume. Added orientation markers and camera rotation angles in the 3D view. Added SUVbw for PET images in the cursor value, ROI information and window center/width, including the fused image in Fusion. Pixel values, ROI values and Window/Level are now shown in true rescaled units for images with a low Rescale Slope (e.g. ADC and SNR maps). Extended the command line: anonymize options, -createSubFolder, DICOMweb support for PACS download and -pacsDate. Universal installer: closes a running MicroDicom before copying files, added the /ARCH=x86|x64 parameter and support for /D= for the install folder. Reduced the size of the user manual and updated it. - Defect fixing: Fixed opening of color DICOM images without Planar Configuration, and color images showing as a black screen. Fixed windowing synchronization between series of different modalities (e.g. PET and CT). Fixed the DICOM server (SCP) hanging on new associations while receiving a large study. Fixed "DIMSE No valid Presentation Context ID" on C-GET/C-MOVE retrieve, and added clearer error messages for failed retrieves. Fixed series-level C-FIND/QIDO queries that sent Patient Name/ID attributes. Fixed DICOMweb issues: QIDO-RS results stopping at the first page, UTF-8 decoding of QIDO-RS values and the WADO-RS Accept header. Fixed the same patient appearing with different ages, and sorting by date in the Preview tab, when a patient has several studies. Fixed an issue in 3D MPR with rotated planes, mirrored rendering in 3D and the 3D view in split layouts. …

Inkscape is an open-source vector graphics editor similar to Adobe Illustrator, Corel Draw, Freehand, or Xara X. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an open XML-based W3C standard, as the native format. In contrast to raster (bitmap) graphics editors such as Photoshop or Gimp, Inkscape stores its graphics in a vector format. Vector graphics is a resolution-independent description of the actual shapes and objects that you see in the image. A rasterization engine uses this information to determine how to plot each line and curve at any resolution or zoom level. Contrast that to bitmap (raster) graphics which is always bound to a specific resolution and stores an image as a grid of pixels. Inkscape can import and display bitmap images, too. An imported bitmap becomes yet another object in your vector graphics, and you can do with it everything you can do to other kinds of objects (move, transform, clip, etc.) While Inkscape does not have all the features of the leading vector editors, the latest versions provide for a large portion of basic vector graphics editing capabilities. People report successfully using Inkscape in a lot of very different projects (web graphics, technical diagrams, icons, creative art, logos, maps).
