Patent ID: 7635982

Claim:
A magnetic resonance apparatus comprising: a receiving coil which receives a magnetic resonance signal from a subject; a resonance signal transmitting unit which transmits the magnetic resonance signal received by the receiving coil with a radio signal of a frequency band different from that of the magnetic resonance signal; an extracting unit which extracts the magnetic resonance signal from the radio signal; a battery which supplies power to the resonance signal transmitting unit; a switch unit which turns on and off power supply from the battery to the resonance signal transmitting unit; a control signal transmitting unit which wirelessly transmits a startup signal indicative of startup and a stop signal indicative of stop; a receiving unit which receives the startup signal and the stop signal that have been wirelessly transmitted; and a control unit which controls the switch unit to turn on the power supply when the receiving unit receives the startup signal and turn off the power supply when the receiving unit receives the stop signal.
