Title:
MAGNETIC RESONANCE IMAGING DEVICE AND METHOD FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2014/199793
Kind Code:
A1
Abstract:
In order to provide a magnetic resonance imaging device that does not use liquid helium and that can stably operate a superconducting magnet operating in driven mode, the present invention is, at a power source unit that supplies current to a superconducting coil, provided with a control unit that controls the current supplied to the superconducting coil on the basis of at least one unit of information among the power supply state from the outside to the power source unit, the operating state of a refrigerator, the temperature of the superconducting coil, the magnetostatic field strength, the current value flowing to the superconducting coil, and the nuclear magnetic resonance signal detected by a detector.
