Patent ID: 8030930

Claim:
A separate type coil for a magnetic resonance imaging system, comprising: a first partial coil in a first partial casing and a second partial coil in a second partial casing, said first partial coil and said second partial coil being connected to a connector for connection to the imaging system via a first cable and a second cable, respectively; An inductive coupler comprising a first part and a second part that are coupled to each other, the first part of the coupler being disposed in the first partial casing and being connected to said first partial coil, the second part of said coupler being disposed in the second partial casing, said first cable being disposed in the second partial casing, and the second part of said coupler being connected to the connector for connection to the imaging system via said first cable; and an equivalent circuit of each coil unit in said first partial coil and the coupler comprising: a coil unit inductance, a capacitance assembly for adjusting the performance criteria of the coil unit, two parts of mutually coupled inductance of the coupler, a detuning loop for the coil unit and an amplifier with one side of said capacitance assembly being connected to said coil unit inductance, the other side of said capacitance assembly being connected to the first part of the mutually coupled inductance of the coupler, one side of said detuning loop being connected to the second part of the mutually coupled inductance of the coupler, the other side of said detuning loop being connected to said amplifier, and the other side of the amplifier being used for connection with the first cable.
