Abstract: A patient couch for use in a medical imaging system that includes a gantry, a power supply unit and a driving unit for positioning the patient couch with respect to the gantry. The patient couch includes at least a first connector for supplying a wireless coil (e.g., a radio frequency (RF) coil for an MRI imaging apparatus) with power. The patient couch is detachably connected to the gantry. The power supply is configured to supply the first connector with power and an optional clock synchronization signal.

Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a transmission channel, a first phase shifter, and a second phase shifter. The transmission channel is configured to arrange, in at least a partial section between a generator and a transmitter coil, radio frequency (RF) pulse signals to be transmitted parallel to one another via a plurality of channels. The first phase shifter is configured to shift at least one of phases of the RF pulse signals to be transmitted via the channels, so that the phases of the RF pulse signals are in a relationship of being different from one another. The second phase shifter is configured to shift, in accordance with a phase amount shifted by the first phase shifter, at least one of phases of the RF pulse signals at a stage prior to inputting the RE pulse signals to the transmitter coil.

Abstract: A medical image imaging system according to an embodiment includes a processing circuitry. The processing circuitry determines a progress in a workflow related to imaging of a subject by a medical image imaging apparatus. The processing circuitry assigns an operation authority for the medical image imaging apparatus to one user terminal among a plurality of user terminals in accordance with the determined progress.
