摘要:
According to one embodiment, an apparatus includes a control unit and a coil unit. The control unit generates a first clock signal, generates a data signal to indicate an operating condition, modulates the first clock signal by the data signal to obtain a modulated signal, generates a clock transmission signal including the modulated signal, and emits the clock transmission signal. The coil unit converts the clock transmission signal into an electric signal, detects the modulated signal from the clock transmission signal, generates a second clock signal synchronous with the first clock signal from the modulated signal, detects an MR signal generated in a subject, digitizes, synchronously with the second clock signal, the MR signal, detects the data signal from the detected modulated signal by using of the second clock signal, controls the operating condition of the coil unit to be the operating condition indicated by the data signal.
