Two Images into one single DICOM File

[giveme21seconds]

Hey Guys i need some Advise,

I need some tips on how to merge to DICOM files into one. I already have a Python script with which I can create a DICOM from a 3D voxel. Now I want to add a color histogram (file format .tif) to the same DICOM. For my special case i can't have two DICOM files (one for the .vox Image and one for the .tif Image). It would be perfect if there was a way to merge those files into one single .dcm, which i can open with f.e. MicroDICOM viewer. I would appreciate any kind of help :)
The VOX is a 3D Image and i converted it into a Multiframe Monochrome DICOM. The TIF image is a 2d color image. I need any Solution to put them into one DICOM Container.

I don't think you can do this with a public element, but if you use a private element for the histogram you likely won't be able to see it in the viewer.

As @scaramallion wrote, this is not supported in DICOM, except if embedded in a private tag (which will not be recognizable by any viewer).
May be you can describe your use case to get a better understanding of your problem.
