I was intentionally handwaving but above is about right in orders of magnitude, i just rolled things up.

Staffing is an interesting one (which I ignored, but good point you can't really) - lots of potential deployments of a small machine like this probably don't look anything like a US standard imaging suite, and aren't going to be staffed the same way. If you run all the numbers in detail you get big variations here, depending on set up.
