Free · Browser-based · No install
A DICOM viewer with real multiplanar reconstruction — every plane freely rotatable, always mutually consistent. Open a study and it runs entirely in this tab. No upload, no account, no server involved at any point.
Works on any Chromium-based browser — Chrome, Edge, Brave, Opera. Not a certified medical device — for review and teaching use.
The part most viewers can't say
There's no upload step because there's nowhere to upload to — no server component exists. Studies are decoded and rendered locally, in memory, for as long as the tab stays open. Close it, and there's nothing left anywhere to clean up.
What it actually does
Axial, sagittal, and coronal — each one independently, freely rotatable around any axis, not locked to 90° from the others. The reference lines on every panel show the real current angle of the others, always. GPU-accelerated, requesting a 16-bit rendering path where the browser supports it and falling back to 8-bit otherwise.
Reconstruct thicker slabs from thinner acquisitions on the fly. Switch between averaging and Maximum Intensity Projection to bring contrast-filled vessels and calcification forward.
Strips patient identifiers and adds fail-safe case-by-case navigation — built for running an actual assessment, not bolted on afterward.
Load a set of teaching cases once, and the source drive can be safely unplugged — everything needed stays fully loaded for the rest of the session. Meant for material a teacher controls and doesn't want sitting around on a shared or lab computer after class ends.
Window/level, zoom, pan, length and angle measurement, an HU probe with an adjustable sample region. Drop a whole .zip of a study straight in — no extracting first. Hide the toolbar and pair it with your browser's own fullscreen (F11) for a completely clean, distraction-free view.

Make it yours
Six color themes, from a clinical Dark Teal to a full-on Terminal or Vaporwave look nobody expects from diagnostic software. Every keyboard shortcut — tools, flip, invert, MPR, mode toggles, all of it — is yours to rebind to whatever actually makes sense to you, saved right there on your own machine. Set it up once the way you actually work, and it stays that way.
“Most of what's out there is either not affordable, or clearly wasn't designed with students in mind. And a lot of the time, what someone actually needs is small — a teacher running one exam, a student reviewing one case. That shouldn't need an install or a hospital IT ticket. It should just open, get used, and be forgotten about until next time.”
