摘要： A magnetic resonance imaging apparatus generates an MR signal from an object to be examined by applying a gradient field pulse generated by a gradient field coil and a high-frequency magnetic field pulse generated by a high-frequency coil to the object in a static field generated by a static field magnet, and reconstructs an image on the basis of the MR signal. The gradient field coil is housed in a sealed vessel. Numerous techniques are disclosed to reduce adverse effects of vibrations caused by rapidly changing gradient coil currents. By judicious use of non-conducting connection components between gantry components at some joint portions requiring electrical contact and at some other portions not requiring electrical contact, the generation of adverse B waves, and/or induced electron flow in response to physical vibration between joint components can be reduced.

摘要： 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.

摘要： Support information including at least a setting image showing a present configuration of placing a patient on a bed and a present configuration of placing an RF coil for the patient is displayed. As necessary, the support information is displayed while including the position of a virtual magnetic field center corresponding to the position of a magnetic field center in the case of moving the bed into a gantry. The displayed support information is stored at a predetermined timing and can be read arbitrarily. By observing the displayed support information, the operator can promptly and easily determine whether the placement configuration of the patient and that of the RF coil at present are proper or not, and can accurately correct the placement configuration of the patient or the RF coil.
