Abstract
Cryogenic instrumentation is becoming more common in the hospital environment. Led by MRI magnets, cryocoolers as well as large amounts of liquid helium and liquid nitrogen are being used in both mobile and fixed installations. Liquid helium is also necessary in the use of SQUID instrumentation. Different methods of attaining low temperatures are compared as to their technical advantages and disadvantages, cost and reliability. Possible new high temperature superconductors would have a considerable impact on dewar systems as well as on changing the emphasis of cryogenic refrigerators and liquid cryogens to temperatures associated with liquid neon, nitrogen or even freon.
