Can I superimpose two different CT data (not two models) ?

Hi,

After loading the two volumes, In the Slicer viewer, you can select one volume as background and the other volume as foreground and then adjust the opacity.

See https://www.slicer.org/wiki/Documentation/Nightly/SlicerApplication/MainApplicationGUI#Slice_Viewers
