How to open an NNT Viewer scan on Mac without Windows

To open a NewTom scan on Mac without Windows, obtain the complete DICOM examination and open that folder or ZIP in a compatible viewer. NNT Viewer and DICOM export are separate sharing options, so a package labeled NNT Viewer is not a guarantee that standard DICOM files are included.

Which NNT package did the clinic send?

What you haveWhat it means
NNT Viewer packageA recipient viewer and examination data. Do not assume the data is a standard DICOM export.
DICOM image files, sometimes with DICOMDIRThe export to request for independent viewers. Copy all images, not the index alone.
2D image gallery or reportSelected views or documentation, not necessarily the reconstructed CBCT volume.

How to open the images

  1. Keep the complete download. Save the package unchanged. Look for DICOM files in all subfolders; there is no single required NNT image-folder name or slice count.
  2. Try the actual DICOM folder. On Mac, choose Open folder in the browser viewer. A viewer-only package cannot be made into DICOM by changing its extension.
  3. Request a separate export when needed. Ask the clinic: “Please export the complete reconstructed examination from NNT as standard DICOM, including all image files, in a folder or ZIP.”
  4. 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.

What to check if it still does not open

NewTom describes Mac use of its software through Parallels Desktop. Its iPad 2D gallery is a different workflow from running the Windows volume viewer. Neither is required to open a standard DICOM export in an independent viewer.

If the export opens but shows only selected pictures, verify that the clinic exported the volume. NNT reports, annotations and planning work are separate from the image series. To obtain an NNT Viewer package, contact the clinic that exported the examination.

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 downloading NNT Viewer convert my files?

No. The recipient viewer and the DICOM examination are different outputs. Ask the sender for DICOM when the package contains only viewer-specific data.

Does the NewTom brand guarantee import?

No. The actual encoding, complete image set and available memory determine whether the export opens. Check the compatibility page and the imported series.
