Low-Cost MRI Technology to Boost Access to MRI Exams in Developing Countries

Such magnets would weigh much less than conventional MRI magnets and could enable the development of mobile or bench-top MRI systems for use in remote areas. New MRI systems based on this technology would reduce the cost, and make MRI imaging more accessible for patients in developing countries.

The magnets, developed by researchers at the University of Wollowong (NSW, Australia), operate at higher temperatures than conventional MRI magnets. The new magnets could maintain their critical operating temperature, even during power outages.

The researchers also developed a new technique to join the superconductor sections. Details of the technique were published in the journal Superconductor Science and Technology, and involve cold-joining the ends of the wire, and then treating the coil in a furnace to retain its superconducting properties

Associate Professor Kim, said, “We’ve shown that our joining method meets the technical needs for use in MRI. If we can get an industry partner we could take this to the next level in providing healthcare services for millions of people worldwide. After 30 years of commercial production, superconducting MRI systems have reached a state of maturity. The demands of the healthcare industry are for high efficiency, low cost and reliable systems.”
