From bathtub to refrigerator

The use of superconducting magnets for high-field magnetic resonance imaging poses a big cooling challenge.


Classic magnet cooling technology comes with operational and environmental issues, related to the venting and refilling of large quantities of helium. These issues are overcome by the Philips BlueSeal micro-cooling technology, which uses only seven litres of helium in a fully sealed system, as described in this Mikroniek article. This is just one step on the technology roadmap towards more patient- and environment-friendly MRI systems. (Image courtesy of Philips)
