Abstract: A couch according to an embodiment is a couch for a magnetic resonance imaging device, and includes a transformable couchtop, a movable couchtop, and processing circuitry. The transformable couchtop is configured to be at least partially transformable and to support a subject. The movable couchtop is configured to cause the transformable couchtop to move into a gantry of the magnetic resonance imaging device. The processing circuitry is configured to control transformation of the transformable couchtop. The processing circuitry is configured to acquire information regarding a receiver coil used in imaging of the subject, and to control the transformation of the transformable couchtop based on the information regarding the receiver coil.

Abstract: According to one embodiment, a magnetic resonance imaging system includes a first power supply, one or more second power supplies and control circuitry. The first power supply supplies power to a magnetic resonance imaging apparatus at a time of power outage of a commercial power supply electrically connected to the magnetic resonance imaging apparatus. The second power supplies supply the power to the magnetic resonance imaging apparatus. The control circuitry determines a state of feeding from the first power supply and the second power supplies to the magnetic resonance imaging apparatus, and performs control of power consumption in the magnetic resonance imaging apparatus based on a determination result of the state of feeding.
