Try it live

This is the real viewer, embedded for hands-on testing and training. Open one of your own studies and follow the feature guides — everything happens on your device, nothing is uploaded.

1. Click Open DICOM (top right) and choose a folder or a .zip, or just drag & drop files onto the viewer.
2. Pick a series from the list to display it.
3. Use the toolbar to window/level, zoom, scroll and measure. Press F for fullscreen, Shift+F for presentation mode.

Tip: for the most space, open the viewer in its own tab. No sample dataset is bundled (to keep the app tiny and private) — use any DICOM study you have access to.

Suggested practice flow

• Navigation & window/level — scroll slices, try the W/L presets.
• Measurements & tools — measure a length and an angle, drop an ROI.
• 3D · MPR · MIP — for a CT/MR series with enough slices.
• Library & tags — link a folder and tag a study.
• Presentation mode — project a series cleanly.
