James, don't fall for the old fiberglas housing trick! Oldest trick in the book, have been forced to use it myself. When it goes "bump bump bump bump..." and I see my own torn-up knee, then I'm less skeptical. Hint: Tape a hot-dog to your kneecap, so they can't pull any old image up and say it is yours!
As for my soft x-ray remark, sorry. I meant medical x-ray, the kind for people, not no Xeroradiography soft. Long story.
As for needing the least S/N for the problem- you are correct; but if you knew the problem, why would you be scanning? Point is, you don't know how much image quality you need until after you find the problem. The insurance company will go nuts if you do a low field scan, can't find the problem, and then need to refer to a high field scan. Not to mention the Lawyers licking their chops.
I never got a scan in an Instrumentarium unit (0.06T) but I got hundreds of scans at 0.1 T, a good month (solid) in the bore at 0.15 (scanning myself late at night- set up the scanner, press return, then dash for the bore! Crazy fun olden days). I bet I have hundreds of hours at 1.5 T - protons mostly; my sodium brain scans suck, apparently. Not much salt in my brain, whatever that means! I'm a sound sleeper, and love the lullabye "whang! whang! Whang!" of a gradient coil.
Funny thing is, permanent magnet gradient coils are MUCH quiter than solenoids. I built a set of gradient coils for a permanent magnet, and I did NO sound abatement. They were quiet! I also worked on sound abatement for a supercon, and man, those babies are LOUD unless you do some serious muffling! Like having your head in a trash can, and a kid hitting the can with a stick!
Back on topic...
If Lunar is selling 60 units, Will they have to pay on Damadien's patent? No, because they are not scanning for cancer. Not to mention the patent must have expired by now.
I digress, but this is fun.
