I can't read the full article but low-T MRI is potentially a big deal IMO because a 0.05T magnetic coil can be air or water-cooled but higher T-magnets (like 1.5 and 3T MRI magnets) have to use superconducting wire and thus must be cooled to sub 60K temperatures (even down to sub 10K) using Helium refrigeration cycles. I worked for a time at a company that made MRI calibration standards (among many other things).
helium refrigeration cycle equals:
- elaborate and expensive cryogenic engineering in the MRI overall design.
- lots of power for the helium refrigeration cycle.
- requirements for pure helium supply chain, which is not possible in many parts of the world, including areas of Europe, North America, etc.
