Patent ID: 8922213

Claim:
A magnetic resonance imaging apparatus, said apparatus comprising: a transmitting coil configured to apply a radio-frequency magnetic field to a subject placed in a static magnetic field; a receiving coil configured to receive a magnetic resonance signal emitted from the subject in response to application of the radio-frequency magnetic field by the transmitting coil; an electronic circuit configured to be connected to the receiving coil; and an overheat protection circuit configured to include a temperature fuse arranged between the receiving coil and a driving control circuit configured to control driving of the receiving coil; wherein the temperature fuse is configured to become an open circuit when a temperature of the electronic circuit exceeds a temperature threshold; and wherein the overheat protection circuit is configured to conduct a magnetic resonance signal received by the receiving coil after the temperature fuse becomes an open circuit, through a receiving circuit configured to process the magnetic resonance signal.
