Do you have the Orthanc log generated when you try to do that ? You might need to use verbose logging. Probably related to some sort of tag issue.

I tried and they uploaded, but I get some errors, and it doesn’t display in the viewer.

BTW, that imports into Osirix just fine, so it has to be some wort of Dicom format incompatibility or missing tags or something. The Orthanc devs will probably have to look into it. I do see some other errors also:

Hello,

Your images contains spaces in the DICOM tags “Image Position Patient” (0020,0032) and “Image Orientation Patient” (0020,0037), which is unexpected.

I have committed a patch to support such images:
https://hg.orthanc-server.com/orthanc/rev/0ea450e1f0ea

This patch will be part of forthcoming release 1.7.3 of Orthanc.

Regards,
