Thanks for pointing at that! But if the description is correct, > ZBO magnets allow practically unlimited system operation without helium refill. ... then is there really still any meaningful relationship between helium supply and the patient wait time for MRIs as westcort complained? Or is it just that there are too few MRI machines in the healthcare system? And, I suppose if anyone here knows -- why is it that NMR magnets at UCLA and UCSF required recycling systems which sound meaningfully less efficient (the UCLA article linked above reclaimed only 90%) rather than using the ZBO tech which is apparently standard in modern MRIs?
