A tool built to get out of the way.

NoustaView is a free, browser-based DICOM viewer. There's no install, no account, and — this part matters more than it might sound — no server in the imaging path. A study you open stays in this browser tab unless you choose to share a de-identified copy.

Why it exists

Most existing DICOM viewers fall into two camps: not affordable, or clearly not designed with students in mind. Meanwhile, a lot of the actual need is small and occasional — a teacher running one exam, a student reviewing one case, a colleague without PACS access who just needs to look at a study once. None of that should require an install or a hospital IT ticket. It should just open.

Exam/Class Mode exists for that specific case — load the cases once, unplug the source drive, and export, printing and sharing stay locked until the tab is closed. It's built for the actual mechanics of running an assessment or a class, not added as an afterthought to a general-purpose viewer.

The name

NoustaView comes from nousta — Finnish for "to rise" or "to ascend." The idea it's named for is a small one: a good view of something shouldn't depend on where you happen to be. The same study should be just as reachable at any time, from anywhere, with nothing more than a browser — and built for a class, a case discussion, or a review.

What it's for, and what it isn't

This is a review and teaching tool. It is not a certified medical device and is not intended for primary diagnostic use. It does not replace a calibrated diagnostic workstation. GPU rendering requests a higher-precision path where the browser supports it, falling back to 8-bit otherwise.
