Abstract
In a magnetic resonance imaging apparatus according to an embodiment, a transmitting coil applies a radio-frequency magnetic field to a subject placed in a static magnetic field. A receiving coil receives a magnetic resonance signal emitted from the subject owing to an application of the radio-frequency magnetic field. A balun is connected to the receiving coil, and suppresses an unbalanced current induced in the receiving coil. An overheat protection circuit indicates that the balun is abnormal when a temperature of the balun exceeds a temperature threshold. An imaging control unit stops imaging when the overheat protection circuit indicates an abnormality of the balun.
