  • Magnetic resonance diagnostic apparatus
    Patent number: 8598879
    Abstract: A magnetic resonance diagnostic apparatus is configured in such a manner that: a high-frequency transmission coil transmits a high-frequency electromagnetic wave at a magnetic resonance frequency to an examined subject; a heating coil performs a heating process by radiating a high-frequency electromagnetic wave onto the examined subject at a frequency different from the magnetic resonance frequency; based on a magnetic resonance signal, a measuring unit measures the temperature of the examined subject changing due to the high-frequency electromagnetic wave radiated by the heating coil; and a control unit exercises control so that the measuring unit measures the temperature while the heating coil is performing the heating process, by ensuring that the transmission of the high-frequency electromagnetic wave by the high-frequency transmission coil and the radiation of the high-frequency electromagnetic wave by the heating coil are performed in parallel.
