    Abstract: In order to prevent quenching caused accidentally in a superconducting magnet, an MRI apparatus vibrates the superconducting magnet in order to prevent quenching of the superconducting magnet in a time period for which a predetermined imaging sequence is not executed (step 210). As a specific method, a gradient magnetic field may be generated by a gradient magnetic field coil for an imaging sequence of the MRI apparatus, or a gradient magnetic field may be generated using a gradient magnetic field coil for vibration provided apart from the gradient magnetic field coil for an imaging sequence. In addition, in a period for which the predetermined imaging sequence is not executed, a phantom may be imaged to prevent the quenching of the superconducting magnet.

    Abstract: A magnetic resonance imaging apparatus includes: a pair of static magnetic field generators separately disposed at the top and bottom of an imaging space in which a subject is placed; a shim magnetic material, disposed on the imaging-space side of each of the pair of static magnetic field generators, for generating a magnetic field to adjust the static magnetic field; a gradient magnetic field generator; a high-frequency magnetic field generator; a temperature sensor for directly or indirectly measuring the temperature of the shim magnetic material; and a controller for controlling the gradient magnetic field generator and the high-frequency magnetic field generator to execute an imaging pulse sequence. The controller determines the inhomogeneity of the static magnetic field from the output of the temperature sensor, considering the change in a magnetic field adjustment parameter due to the temperature change of the shim magnetic material, and causes a warning message to be presented if the determined static magnetic field inhomogeneity has exceeded a predetermined allowable value.
