People who have been scanned for some serious condition may have strong personal feelings about such artefacts — but for the rest of us, they are pretty lousy museum objects. But your post makes me change my mind.

There are quite a few spinning CT scanners on YouTube. I show some of them in a post here

So what really strikes me when seeing these clips is how the strip act changes the scanner as a museum artefact — from being an anonymous white silent behemoth to a lively noisy object with a lot of fascinating detail. Strong presence effects!
As a commentator on the ‘CT at max speed’-movie says (his spelling):

Monster Mashine, when you could see this, you never yould lie in it, it’s really fast and scary

In other words: imagine having that washing-machine-centrifugish thing spinning around your body! What if the bearings crack?
I’ll try to convince my colleagues that we shall acquire a used ‘live’ CT scanner from the National Hospital for our exhibition? We probably have to comply with some basic security rules for displaying machines at work — but that aside, I think it would be worth trying.
