Doomina DICOM Viewer

Doomina DICOM Viewer is a free, browser-based viewer for medical images. Open CT, MR, ultrasound, PET, X-ray and more — directly from your computer. In local mode it runs entirely in your browser and your files are not uploaded. An optional free account adds a cloud image bank and sharing — see the Privacy Policy.

What you can do

• Open a folder (CD/USB), a .zip, a DICOMDIR or individual .dcm files.
• Window/level with presets, pan, zoom, scroll/cine through slices.
• Measurements: length, angle, ROI (rectangle/ellipse), arrows and text.
• Advanced rendering: MPR, MIP, 3D, PET/CT fusion and study comparison.
• Multi-panel layouts (1×1, 1×2, 2×2) with synchronized scrolling.
• A real library folder on your computer to keep studies, with free-form tags you can filter by.
• A clean presentation mode for teaching and projecting.
• Install it as an app (PWA) and use it offline.

Why it's different

• Private by design — images are decoded and rendered on your device; nothing leaves your computer.
• No install, no sign-up, free — just open the page.
• Works offline once loaded, and can be added to your home screen / desktop.

Cloud DICOM Bank (optional)

Want to keep your studies online and reopen them from any device? The optional, paid Cloud DICOM Bank adds an account where you can store, organize and (soon) share studies. The local viewer above stays 100% free with no account — the cloud is opt-in. See the plans & pricing (currently in early access).

Next steps

• Quick start — open your first study in under a minute.
• Loading studies — folders, zips, DICOMDIR and the library folder.
• Try it live — an embedded, fully working sandbox for testing and training.
