If we could move from liquid helium to liquid nitrogen cooled magnets, then the cost of such machine (total cost, both capital and operational) will drop a lot.

If we could move from liquid helium to liquid nitrogen cooled magnets, then the cost of such machine (total cost, both capital and operational) will drop a lot. Countries deploying MRI machines today could increase coverage and lessen wait times. My relative recently waited 2 months for non urgent MRI (assigned by doctor). Some countries have it even worse. And MRI which can be cooled with a conventional electric freezer would cost order of magnitude less, probably. Which mean it could be deployed even in the rural regions and underdeveloped countries, like some x-ray machine today (it is more complex tool of course, this was a metaphor). So that's the gist of it, reducing the infrastructure costs significantly. And the interesting thing about diagnostic healthcare is that their potential market is a perfect circle of all humans on the planet. The maximum possible market, because we all get old, ill and die eventually. All need better diagnostics, but not all needs a new car or new computer or new gun, or new chat application.
