How to open a Sidexis 4 Viewer disc on Mac or iPad

A disc containing only the 2D Sidexis 4 Viewer package needs a separate DICOM export for an independent viewer on Mac or iPad. A Galileos 3D volume package and a DICOM Media export are different disc layouts, so identify the contents before choosing an import route.

Three packages that should not be confused

What you haveWhat it means
Start Sidexis 4 Viewer.exeThe Windows recipient viewer. The launcher and a 2D viewer package alone are not a plain DICOM examination.
DICOMDIR and DICOMRMA DICOM Media layout documented for older Sidexis/Galaxis exports. Preserve both.
.gwg beside a …_vol_0 folderA Galileos Viewer volume package. Use the separate Galileos folder instructions; this is not the 2D Sidexis Viewer case.

How to open the images

  1. Inspect the complete disc. Look beside the launcher for image folders. Keep the folder names and their contents unchanged.
  2. Select the DICOM Media parent folder. If DICOMDIR and DICOMRM are present, import their common parent folder. On Mac, the browser button is Open folder.
  3. Import the folder on iPhone or iPad. In Ossidex, tap +, then Folder. Select the copied folder containing the images, not just the launcher or index. If you received a ZIP, choose Files / ZIP instead. These are the English app labels.
  4. Ask for a different export if needed. For a viewer-only 2D package, ask the clinic for DICOM exam export or DICOM Media export. For CBCT, specify the complete reconstructed 3D volume.

What to check if it still does not open

The Windows launcher can require .NET; installing a DICOM viewer on an iPad does not run that launcher. Re-exporting from the clinic’s Sidexis installation resolves the missing-image case.

A Galileos volume is a separate exception supported by the native app, with its own geometry limits. Do not treat every Sidexis-branded disc as that format. See the .gwg and volume-folder guide.

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

Does Wrap&Go always mean DICOM?

No. Wrap&Go can package the recipient viewer. Check for actual DICOM image files or a recognized Galileos volume.

Can I just install .NET on iPad?

That does not provide a way to run the Windows Sidexis viewer. Request the DICOM images instead.
