Abstract:
1. A magnetic resonance imaging apparatus comprising: a static magnetic-field magnet configured to generate a static magnetic field in an imaging area in which a subject is to be placed; a main coil that is provided on an inner side of the static magnetic-field magnet, and which is configured to apply a gradient magnetic field onto the subject when placed in the static magnetic field; a shield coil that is provided between the static magnetic-field magnet and the main coil, and which is configured to shield the gradient magnetic field generated by the main coil; a radio-frequency coil that is provided on an inner side of the main coil, and which is configured to apply a radio-frequency magnetic field onto the subject placed inside the static magnetic field; a radio-frequency shield that is provided between the main coil and the radio-frequency coil, and which is configured to shield the radio-frequency magnetic field generated by the radio-frequency coil; and an inner-layer cooling pipe that is provided on an inner side of the main coil and between the radio-frequency coil and the radio-frequency shield, and which is configured to pass a coolant in the inner-layer cooling pipe.
