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,
