Very impressive for a MRI system that is mobile. Hope this new system will bring down MRI scanning cost worldwide and that the Chinese researchers can also improve on the currently long scanning time of 20-30mins.

Ningbo develops nation's first liquid helium-free MRI system

The system relies on refrigeration instead of the commonly used liquid helium to cool its core components which comprise superconducting magnets, according to a company representative at Xingaoyi Medical Equipment.
...
The newly developed system is mobile and can perform medical diagnosis for people in multiple postures, something that is difficult to achieve using conventional superconducting magnetic resonance systems.

The company has to date filed for eight invention patents for the system.

Liquid helium is a scarce resource and traditional superconducting magnetic resonance equipment accounts for nearly 30 percent of the global liquid helium consumption.
