How to overlay segmentation dcm on image dcm

Hello,

How can I overlay the segmentation dcm file on the original dcm file?

I have a model takes an nifti input file and gives you a nifti file which shows the segmentation. To view with OHIF, I am converting the input files above to dcm and passing to OHIF. I cant figure out how to combine the seg dcm and original dcm files. Is there a way to easily combine both the segmentation and the original dcm files?

@alireza any thoughts on this? Also any suggestion on where to get great freelance developers with experience in OHIF and PACs?
