PrologicSign Viewer documentation

Getting started with the Windows viewer, and what the web viewer preview needs.

Windows viewer

The complete user guide, with every tool and keyboard shortcut, is in the PrologicSign PACS documentation.

Install

  1. Download the installer from the Downloads page.
  2. Run it as an administrator. On the Product page choose PrologicSign Viewer. For a silent install use PRODUCT=viewer.
  3. Start PrologicSign Viewer from the Start menu or the desktop.

That installs only the viewer. If the computer runs a PrologicSign PACS or Router whose product includes the Viewer, install that product instead: it adds the viewer and uses the same key.

Activate a key

Without an active key the viewer opens local files in basic mode and shows an Activate... button on the toolbar. To evaluate, get a free Developer key on dicomkit.plogic.dev: every feature of the viewer, one computer, 7 days, renewable once, not for production.

  1. Press Activate... and enter your key.
  2. Without internet, save an activation request to a file, upload it in the customer portal, and import the license file you get back.
  3. Writing the license needs administrator rights once. If asked, right-click the viewer, choose Run as administrator and activate again.

Open images

  • Files: Ctrl+O. Folder, CD or USB: Ctrl+Shift+O. You can also drag files and folders onto a viewport.
  • Other PACS (needs a key): press Other PACS, add the PACS name, AE title, host and port, press Test for a C-ECHO, then search and retrieve. C-GET is the default and needs no inbound port. C-MOVE opens a receive port (default 11113) while it runs, and the other PACS must know this computer's AE title, address and port.
  • The other PACS must allow this computer to query and retrieve.

Limits of this release

  • Windows only. No MPR, 3D or image fusion, no hanging protocols and no linked scrolling.
  • DICOM over TLS is not available for Other PACS: a connection marked TLS is refused with a message and is never sent unencrypted.

Web viewer preview

The web viewer is not generally available. There is no download or license yet, and details may change. Contact us if you would like to see it.

It is a folder of static files. There is no installer, database or server process: the browser does the work and talks directly to your image server.

  • Hosting: any web server or static host, at the site root or under a sub-path. .wasm files must be served as application/wasm.
  • Images: a DICOMweb server (QIDO-RS with WADO-RS or WADO-URI), or local files.
  • CORS: the image server must allow the viewer's origin, or be on the same origin or behind a reverse proxy.
  • Settings: an editable config.json holds data sources and branding, with no rebuild.
  • License model: a signed license file bound to your domain names and checked in the browser. The customer portal does not issue these yet.
