Saga DICOM Viewer
Saga DICOM Viewer is a free, browser-based DICOM viewer for opening .dcm files without installing software. Drag a file or a study folder into the page and the images render locally; nothing is uploaded and no account is needed. It runs on Mac, Windows, Chromebook and Linux in any current browser.
Built on the open-source OHIF v3 platform with a Saga shell. Alongside image review (scroll, window/level, pan/zoom and basic measurements), it includes a DICOM tag browser and tag editor with VR-aware validation and save-as, a conformance validator that checks loaded files against the NEMA PS3 standard and links each issue to its spec section, and a launcher for opening public studies from the OHIF demo dataset or NCI Imaging Data Commons, or connecting to a DICOMweb server.
For integration engineers, researchers, students and clinicians who need to open or check a DICOM file quickly. Not for diagnostic use. Made by Saga IT, a healthcare IT consulting and software firm.

Ossidex
Ossidex is a DICOM viewer for iPhone and iPad, with a browser viewer for 2D and MPR review. It opens CT, MRI, dental CBCT, X-ray and ultrasound studies from disc folders, compressed archives, cloud links and DICOMweb-connected PACS. The app provides 2D viewing with window presets and cine, multiplanar reconstruction (MPR) with linked crosshairs, oblique planes, slab MIP and 3D volume rendering. Dental tools create panoramic views and cross-sections, and support implant planning with a library of 16,000+ implants from 129 manufacturers, proximity warnings and PDF reports. Users can measure lengths and angles, review ROI and Hounsfield unit values, annotate images, and export images, PDFs and MP4 videos. Dentists, implantologists, radiologists, other clinicians and patients use it to review studies. Images are processed on the device without an account or scan upload. Advanced tools on personal studies require an optional Pro subscription.

OmniDICOM
OmniDICOM is a desktop DICOM viewer and metadata editor for research and education on Mac and Windows. Open local studies, compare series, make measurements, play cine sequences, and inspect or edit DICOM tag values. Viewing tools include multiplanar reconstruction (MPR), maximum intensity projection (MIP), 3D volume rendering, and DSA subtraction. PACS and DICOMweb tools support study transfer; export options include images, video, DICOM, and STL models. Professional adds a processing bench with stacked filters and analysis tools such as histograms, profiles, and time-intensity curves. A 14-day Professional trial starts at first launch; trial exports have limitations, and continued unrestricted use requires a paid licence. Basic starts at US$10/month or US$99/year per machine; Professional is US$45/month or US$449/year. OmniDICOM is not a medical device and is not intended for diagnosis or clinical decision-making.

Mango Viewer
Mango Viewer (Multi-image Analysis GUI) is a viewer for medical research images designed to support a wide range of file formats, including DICOM, NIfTI, ANALYZE, and more. It provides extensive tools for navigating and analyzing medical imaging data, including multi-planar viewing (axial, sagittal, coronal), surface rendering, and region of interest definition and analysis. Mango offers a simple and intuitive user interface that supports scripting and batch processing to automate repetitive tasks. It includes features like image overlay, image fusion, 4D data visualization, and dynamic contrast-enhanced imaging analysis. ROI tools support statistics extraction such as volume, mean, and standard deviation, and ROIs can be drawn manually or generated algorithmically. Mango supports multi-image handling for comparative studies and integrates plugins for extended functionality, such as brain mapping, tractography, and perfusion analysis. It is platform-independent.
