摘要： A receiving coil for a magnetic resonance system includes an antenna unit and a locating unit. The locating unit is used for locating a subject to be examined and is positioned inside the antenna unit. The receiving coil for a magnetic resonance system may improve a patient's level of comfort, reduce the complexity of operation, and improve the coil's signal-to-noise ratio.

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.
