Available for Mac and Windows

Desktop DICOM viewing, plus a local workstation server for Mac.

Download DN Viewer — a DICOM reader and DICOM viewer for Mac and Windows — to open studies, connect to DICOM servers, use near-instant MPR, 3D rendering, and AI-powered segmentation and volume calculation tools, and keep reporting inside one fast desktop workspace.

Built for MRI-heavy workflows: your pane layouts come back exactly as you left them for each study, so you spend time reading, not rearranging.

The included DICOM client lets you query and retrieve from an existing remote PACS with C-FIND, C-GET, and C-MOVE. The optional Workstation Server is different: it receives studies and makes locally stored studies available to other workstations.

Near-instant MPR Move through multiplanar views with minimal waiting.

Overview

Built for faster desktop review on Mac and Windows.

DN Viewer + Workstation combines native image review with two clearly separate DICOM roles: the included client retrieves from remote PACS, while the optional Mac App Store server receives and shares locally stored studies.

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.

Connectivity & Access

  • Included DICOM client: query and retrieve from an existing remote PACS or worklist with C-FIND, C-GET, and C-MOVE.
  • DICOMweb support for modern web-based imaging workflows.
  • Launch DN Viewer from teleradiology websites using DICOMweb or a secure manifest URL. See launch URL format →
  • Open local DICOM files directly from USB, CD/DVD, or any folder.

Workstation Server for Mac App Store

  • Receive studies locally: accept incoming studies from other workstations and keep them in the selected local storage location.
  • Serve local studies: let other workstations find and retrieve received studies through C-FIND, C-GET, and C-MOVE.
  • Separate subscription: Workstation Server is available only in the Mac App Store edition and requires a monthly subscription. The standard remote-PACS client remains included without this purchase.

Visualization & Review

  • Near-instant MPR for faster spatial review.
  • 3D render inside the same reading workflow.
  • MRI layouts reopen automatically for each study — no rearranging needed.

AI & Reporting

  • AI-powered segmentation and volume calculation tools for faster region selection. Currently available on macOS only — to use AI segmentation on Windows, contact support for the research edition.
  • AI-assisted reporting with speech-to-text, AI-enabled drafting, and validation checks — significantly cutting down report drafting time.
  • Chat and AI features without leaving the viewer.

Platform

  • Native desktop app for Mac and Windows — not a browser-based viewer.
  • Available for Mac and Windows from the app stores or direct installers.

DN Viewer + Workstation for Mac and Windows.

Mac + Windows

DN Viewer runs as a native app, so near-instant MPR, 3D rendering, AI-powered segmentation and volume calculation tools, and study navigation stay fast and responsive in a true desktop workflow.

  • Native desktop app for Mac and Windows.
  • Available for Mac and Windows from the app stores or direct installers.

By downloading and using DN Viewer you agree to the End User License Agreement.

Mac App Store Add-on

DN Viewer Workstation Server.

Mac App Store

Turn the Mac App Store edition into a local DICOM workstation server: receive studies from other workstations, retain them in local storage, and serve them onward to configured clients.

  • Receives incoming studies directly from other workstations.
  • Serves received studies through C-FIND, C-GET, and C-MOVE.
  • Requires the separate monthly Workstation Server subscription; App Store pricing is shown in your region.
  • Not required to use DN Viewer’s included remote-PACS query and retrieval tools.
Enterprise

Need cloud backup, PACS server, or team sharing?

Enterprise plans add custom cloud backup, dedicated PACS server integration, enterprise-level study sharing across sites, and advanced reporting workflows.

Teleradiology providers can also launch DN Viewer directly from their own web portal with a DICOMweb study URL or manifest. View integration guide →

FAQ

Questions about DN Viewer + Workstation.

Where can I download DN Viewer?+

DN Viewer is available for both Mac and Windows. Download it from the Mac App Store or Microsoft Store, or use the direct installers provided on this page.

Does DN Viewer work as a DICOM reader as well as a viewer?+

Yes. DN Viewer opens and reads DICOM files from local folders, USB drives, CDs, or directly from a PACS or DICOM server. Its included client can query and retrieve from remote PACS with C-FIND, C-GET, and C-MOVE.

What is the DN Viewer Workstation Server subscription?+

It is a separate monthly subscription for the Mac App Store edition. It enables a local server mode that receives incoming studies from other workstations and serves the received studies through C-FIND, C-GET, and C-MOVE. It is not needed for the included remote-PACS query and retrieval workflow.

Is DN Viewer available for both Mac and Windows?+

Yes. DN Viewer is a native desktop app for both macOS and Windows. The Mac version is optimised for Apple Silicon (M1/M2/M3/M4) and available on the Mac App Store. The Windows version is available on the Microsoft Store and as a direct .exe download.

How is DN Viewer different from a web-based DICOM viewer?+

DN Viewer is a native desktop application, not a browser-based viewer. That means faster image loading, GPU-accelerated MPR and 3D rendering, no internet dependency for local files, and no browser tab overhead. Your reading layout persists between studies automatically.
