Abstract:
1. A magnetic resonance diagnostic apparatus comprising: a magnetostatic field coil that forms a magnetostatic field; a gradient coil that superimposes a gradient magnetic field onto the magnetostatic field; a high-frequency transmission coil that transmits a high-frequency electromagnetic wave at a magnetic resonance frequency to an examined subject placed in the magnetostatic field; a high-frequency reception coil that receives a magnetic resonance signal transmitted from the examined subject; an image generating unit that generates a magnetic resonance image of the examined subject, based on the magnetic resonance signal; a heating coil that performs a heating process by radiating a high-frequency electromagnetic wave onto the examined subject at a frequency different from the magnetic resonance frequency; a measuring unit that, based on the magnetic resonance signal, measures a temperature of the examined subject changing due to the high-frequency electromagnetic wave radiated by the heating coil; and a control unit that 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.
