Chromium browser recommended (Chrome/Edge) — folder loading may not work in Firefox/Safari.
16GB RAM recommended for large or multi-study loads.
GPU rendering — you'll be asked next whether to enable it.
100% local. Nothing is uploaded or sent to any server — works fully offline once loaded.
Your current browser doesn't look Chromium-based — folder loading or rendering may not work correctly here.
🖥 GPU rendering
Enable GPU (WebGL2) rendering for smoother contrast/zoom dragging and real-time MPR reslicing? This needs to be set before loading files. You can't reliably change this mid-session once volumes are loaded.
🌄 About NoustaView
NoustaView is a free, browser-based DICOM viewer — no install, no server, no account. Everything runs locally in your browser tab.
The name comes from nousta, Finnish for "to ascend" — the aim is to help you rise to a clearer view of what's in front of you.
Created by
Dr. Chan Kin Wong Radiologist & Interventional Radiologist Kuala Lumpur, Malaysia
Built to make DICOM access easier for everyone — colleagues without PACS access, students, and especially for running exams, where Exam Mode hides patient identifiers and adds fail-safe navigation between cases.
Key features
Window/level, zoom, pan, length/angle measurement, HU probe with adjustable ROI
Multiplanar reconstruction (MPR) — all three planes freely rotatable around any axis and always mutually consistent, adjustable slab thickness with Average or MIP (Maximum Intensity Projection) combining, optional GPU-accelerated real-time reslicing
ZIP files load directly — no need to extract first
Exam Mode (anonymized, fail-safe case navigation) and Class Mode (load-once-then-safe-to-remove-source)
Switchable color themes (Dark Teal, Dark Amber, Light) — image panels always stay black regardless, for correct windowing/contrast
Important
This is a review/teaching tool, not a certified medical device — not for primary diagnostic use. GPU rendering requests a higher-precision (16-bit float) path where the browser supports it; falls back to 8-bit otherwise (an earlier rendering artifact was traced to something unrelated — a texture row-alignment issue — and this path was confirmed not responsible). This does not replace a calibrated diagnostic workstation.
Privacy
No data ever leaves your device — there is no server component of any kind.
⌨ Keyboard Shortcuts
Click "Change", then press any key to rebind it. Picking a key that's already in use takes it from that shortcut instead — it's left unbound (flagged below) until you give it a new one. Saved on this device/browser only — a different computer or a cleared browser keeps the defaults.
