Device domains for human clinical studies

Can I include device domains DI and DU with human clinical trial SDTM submission? My study captures some device information related to CT imaging.

I tried to include this in the submission package, but I got a "Dataset class not recognized" for DI. (DI is defined as special purpose domain in SDTM IG for medical devices)

DU was accepted as custom Findings domain

Thanks,
