    摘要： A local coil for an MRI system includes a signal antenna to receive a magnetic resonance signal and a tuning/detuning circuit to subject the signal antenna part to switch control according to a control signal. The tuning/detuning circuit is connected to the signal antenna part. The tuning/detuning circuit includes a control signal interface, a resonant circuit and an AC/DC conversion circuit. The control signal interface receives the control signal. The resonant circuit includes a diode. The AC/DC conversion circuit converts an alternating current generated by an electromagnetic wave to a direct current. The AC/DC conversion circuit is connected in series with the diode. A small detuning control current may be used, and detuning control circuitry may be reduced.

    摘要： A local coil and a magnetic resonance imaging system are provided. The local coil includes an antenna part, an adjustment part and a transmission part. The antenna part includes a first capacitor connected in series for adjusting a frequency of the antenna part. The adjustment part includes a tuning/detuning diode and is connected in parallel to the first capacitor, and the tuning/detuning diode is used for adjusting tuning and detuning of the antenna part. The transmission part includes a radio-frequency transmission line that connects the antenna part and the adjustment part, and the transmission part provides a phase difference of an odd multiple of 180° between the antenna part and the tuning/detuning diode.
