摘要： A magnetic resonance imaging apparatus includes a probe unit and a control/imaging unit. The probe unit includes a converter converting a sampled magnetic-resonance signal into a digital signal, a first transmitter converting the digital signal into a first-radio signal, a first receiver receiving and performing detection on the second-radio signal to obtain a first-received signal, and a clock-regeneration unit regenerating a clock component from the first-received signal to generate a regenerated-clock signals. The control/imaging unit includes a second-receiver receiving the first-radio signal to obtain a second-received signal, a data processor performing data processing on the second-received signal in synchronism with a reference-clock signal to obtain a video signal, and a second transmitter which modulates a carrier wave using the reference-clock signal, converts the reference-clock signal into the second-radio signal, and transmits the second-radio signal through the second-wireless channel.
