Your right it is speculation but not completely out of left field. Dean said in a previous CC the FDA had a question regarding vibration. His said it not me...Look at the proto picture. It has a very lightweight base thats suppose to support a spinning gantry at 70-RPM?. They also show it titled with it's CG extending out from the center of the the base. All supported with a small set of castor wheels? This just does look hardy enough to be a real field unit or support a rotating Xray emitter and detector which have substantial mass.
