摘要： A magnetic resonance imaging apparatus according to an embodiment includes a radio frequency coil and a control signal transmitting unit. The radio frequency coil is that receives a magnetic resonance signal emitted from a patient as a result of an application of a radio frequency magnetic field thereto and to transmit the received magnetic resonance signal via a wireless communication. The control signal transmitting unit that transmits control information that collectively defines operations to be performed by the radio frequency coil during a predetermined repetition time period, to the radio frequency coil via a wireless communication, prior to the start of the operations performed during the predetermined repetition time period. Further, the radio frequency coil that receives the control information via a wireless communication and to perform the operations on the basis of the received control information.

摘要： In a magnetic resonance imaging apparatus, a transmission RF coil is configured to emit an RF pulse generated by using a first clock. In addition to an echo signal emitted from a patient, a reception RF coil is configured to further receive the RF pulse emitted by the transmission RF coil and configured to transmit, via a wireless communication, a multiplexed signal in which the echo signal digitalized by using a second clock, the RF pulse, and the second clock are multiplexed together. Wireless receiving circuitry is configured to receive the multiplexed signal via a wireless communication. Correcting circuitry is configured to correct the phase of the echo signal on the basis of the RF pulse and the second clock restored from the multiplexed signal received via the wireless communication. Reconstructing circuitry is configured to reconstruct an image by using the corrected echo signal.
