    Abstract: 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.

    Abstract: A local coil assembly for an MRI apparatus includes an RF channel setting unit, a basic coil having a first slot, and a first additional coil connected to the first slot. Each of the basic coil and the first additional coil includes one or more receiving channels. The RF channel setting unit is configured for setting a receiving channel of the basic coil and a receiving channel of the first additional coil. The basic coil is configured for receiving an RF signal according to a receiving channel set by the RF channel setting unit. The first additional coil is configured for receiving an RF signal according to a receiving channel set by the RF receiving channel setting unit. The present teachings are compatible with multiple coils, and support the combined use of multiple coils.
