In fact the > form on the table is my personal molded shoulder and head restraint so > I don't try to move ;-) That reminds me of my first job in the industry. We built CAT scanners as shown by the renderings on this page: http://www.preferredpacsconsulting.com/ContactUs.html The rendering in the left panel shows the operator's table. The rightmost device on it is a plain old camera for snapping pictures. Our CAT scanner used 220V. That said, the room that housed it was custom built for it. The room that houses your medical device was probably also custom built for it. Thank you, -- Don Kuenz KB7RPU
