VTK DICOM useage

Hello,

I am just getting into VTK, and I need to render CT-Scans. I would ideally like to able to render 2 CT-Scans within 1 volume. And be able to move them as actors from within the code, not the interactor. I was looking into GDCM, and I couldnt configure that. I did get something showing, but it was not exactly to my liking. Is there any recommendations to get started. Note I am planning on integrating this with QML
