    摘要： An adapter includes a control circuit, a control signal interface, a first input signal interface, a second input signal interface, and a first output signal interface. The control signal interface receives a tuning/detuning signal, and the control circuit switches, according to the tuning/detuning signal, the first input signal interface and the second input signal interface to be in conduction with the first output signal interface.

    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.
