Abstract

A magnetic resonance imaging apparatus includes a superconducting magnet including a superconducting coil that is cooled to a normal temperature at which superconductivity is achieved, and a coil cooling device that cools the superconducting coil by heat conduction due to contact between a heat conduction member that is cooled via a cold head and the superconducting coil to cool the superconducting coil to the normal temperature. A processor of a magnetic resonance imaging system calculates an operable time point (excitation completion time point) at which the magnetic resonance imaging apparatus is able to start operating after demagnetization of the superconducting magnet is started based on a demagnetization start time point at which the superconducting magnet is demagnetized and a design value of the magnetic resonance imaging apparatus, displays an excitation completion time point on an operation screen 250-1 of a display, and notifies an operator of the operable time point.
