摘要： 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.

摘要： A medical data processing device according to an embodiment includes processing circuitry. The processing circuitry acquires estimated data related to a state of a biological organ at a first timing, and actually measured data indicating the state of the biological organ at the first timing. The processing circuitry calculates a parameter based on the estimated data and the actually measured data. The processing circuitry estimates a state of the biological organ in a predetermined time phase at a second timing different from the first timing based on the parameter and the estimated data in the predetermined time phase.

摘要： An information processing apparatus according to an embodiment of the present disclosure includes a processing circuitry. The processing circuitry obtains a first g factor generated by using first magnetic resonance data acquired through a first parallel imaging process performed by using a plurality of reception coils and a second g factor generated by using second magnetic resonance data related to a second parallel imaging process performed by using the plurality of reception coils. The second parallel imaging process is different from the first parallel imaging process. The processing circuitry adjusts the first g factor so as to reduce a difference between the first g factor and the second g factor.
