3D Rendering of Tomosynthesis

I’m a newbie in using 3D Slicer, so maybe I am missing something obvious.
I am trying to view breast tomosynthesis images that I got from TCIA, and though I can see the image in different planes, I cannot get it to show the 3D image.
Maybe I’m doing something wrong, or maybe tomo dicom files are somehow structured differently.
Would appreciate any advice on how to make it work.

I’ve only seen a few of those, but I know they have a very specific DICOM encoding that is different from other images. A specific dicom plugin may be required to handle them (i.e. a python script that maps them to Slicer’s concept of a volume).
