Slicer should be pretty tolerant of missing dicom ags, but as a baseline you could consider the ones listed here:

[https://www.slicer.org/wiki/Documentation/4.10/Modules/CreateDICOMSeries](https://www.slicer.org/wiki/Documentation/4.10/Modules/CreateDICOMSeries)

Or, if you [load the numpy data](https://discourse.slicer.org/t/creating-volume-from-numpy/658/2) you can create a volume node and then export it as DICOM via the Data module.
