Overview

Built for faster desktop review on Mac and Windows.

DN Viewer focuses on what matters most: native speed, direct DICOM server access, near-instant MPR, 3D rendering, AI-powered segmentation and volume calculation tools, and reporting tools that stay inside the app.

Why It Stands Out

A desktop workflow built for speed and focus.

This is not a browser-based viewer. It is a native app for Mac and Windows designed for fast image review and direct access to the studies you need.

MRI advantage: save your reading layout once and it comes back automatically for each new study. No manual rearranging, no loading screens — your protocol is just there.
