The increasing scarcity of helium gas used in Magnetic Resonance Imaging (MRI) scanners, has spurred a medical imaging vendor to continue to develop helium-free MRI systems.
MR Solutions (Guildford, Surrey, UK) developed the first helium-free MRI system already in 2013, for use in preclinical superconducting MRI systems. The company pioneered the helium-free cooling system, which does not use a liquid helium cooling jacket, and is currently developing a 7-T helium free scanner. The new system will benefit medical MRI research, which is at risk from the global shortage of helium.

Dr. David Taylor, physicist and CEO of MR Solutions, said, “Following a number of years of research and development with our magnet partner, we have been able to dispense with the usual liquid helium cooling system by using a revolutionary magnet design incorporating superconducting wire. This enables the use of a standard low temperature fridge to cool the magnet to the required 4 K. This has resulted in a scanner with improved performance, less costly to buy, lower running costs and no need for the building modification works which were required for the old bulky MRI systems.”
