File-opening guide

My DICOM link opens a web page instead of a scan

If a DICOM link returns a sign-in page or online viewer, open that link in your browser and download the actual image files there. Then import the saved folder or ZIP into Ossidex; saving the web page or renaming it does not download the scan.

What you haveWhat it means
A sign-in pageThe file is behind a portal session. Authenticate in the portal and use its download workflow.
An online image viewerThe link points to an application. Find its image-export function or ask the clinic for DICOM.
An HTML file in DownloadsThis is page content, even if its filename ends in .zip or .dcm. It is not the examination.

How to open the images

  1. Read the import message. Ossidex distinguishes a link opening a sign-in page from one opening an online viewer. Follow the browser-download route for either case.
  2. Use the portal in Safari. Sign in if requested and select the examination’s image download. Download controls and permissions differ by portal; a report button may return only a PDF.
  3. Import the resulting file. Save the actual archive to Files. In Ossidex choose + → Files / ZIP, or Folder for extracted images.
  4. Request access when no download is available. Ask the clinic for a complete DICOM export through its approved sharing method. Keep credentials in the portal rather than adding them to a shared URL.

What to check if it still does not open

The app’s English message begins This link opens an online viewer, not a file. for that response. A related sign-in message asks you to authenticate and download in the browser. These messages describe the response, not damage to the underlying examination.

An expired link, missing download permission or an unfinished portal export must be resolved with the sender. A direct import cannot turn HTML into pixels or bypass authentication. A downloaded ZIP still needs to contain the full image series.

Viewer options and format limits

On a Mac, open the browser viewer and choose Open folder for the complete DICOM folder or Open files for a ZIP. Browser format and memory limits differ from the iPhone/iPad app; a successful import does not establish that the examination is complete.

See the matching format or export guide and tested samples and compatibility limits. Ossidex is a viewer and planning aid, not a diagnostic device.

Frequently asked questions

Can I rename the downloaded HTML to ZIP?

No. The content remains a web page. Repeat the download using the portal’s image-export option.

Does every cloud sharing link work directly?

No. Some links need a browser session, an intermediate download page or permissions. Downloading locally and importing from Files is the fallback.
