Here's a thought that has occurred to me many times: "gee, I'd like to study x instrument in y museum or collection, I should check if there are CT scans of it"
Much more often than not, there are not scans of the instrument in question. I realize that this is the case for a reason, namely that it's expensive to get access to the instrument, the equipment, and the few people with the specific knowledge required to take and render usable scans.
I am sure that many of you have experienced the same thing. Perhaps if enough people come together, though, we could do something about it. Provided we know what we want scanned, who we want to scan it, and how much it would all cost, we could go about getting the money together to do it, and crowdfunding seems the obvious 21st century way to do it.
Please share your thoughts.
