Do you have tomographic data to display?
Set up a thin vertical ‘wall’ prim above a side view of the object. This gets the tomography slices textured on it. When the wall moves, the slice changes.
Provide some controls to allow moving the prim back and forth (allow anyone to move, perhaps, and a scanner to replace it if it gets lost, while the moveable prim dies if it’s moved too far from the base).
Controls also allow the user to set the ‘wall’ to move at a constant speed.
