There are a lot of applications that are surprising. I’ve scanned for salmon farmers (is that the term?) who want to check they are breeding good fish and are looking at spine alignment.
I’ve scanned logs for forestry managers who want to look at something in their trees.
I’ve scanned old hearts that have been sitting in formalin for decades.
All are probably better at higher field strength but maybe some of that can be compensated for by scanning for longer? A log isn’t going to move, and a dead fish scan is likely only limited by the time it takes for it to rot.
I’d be scared of scanning unknown things, it might be a low field MRI, but it’s still a big magnet.
