1. A quad-core radio frequency coil circuit, comprising:
a coil module configured to receive a nuclear magnetic test signal and generate an induction signal according to the nuclear magnetic test signal; and
a front-end module connected to the coil module and configured to generate the nuclear magnetic test signal and collect the induction signal;
wherein the coil module comprises a first coil array and a second coil array of two combined nuclides, and a center position of the first coil array coincides with a center position of the second coil array, the first coil array and the second coil array are designed through using a double-layer nested structure;
wherein the first coil array comprises a first sub-coil array of a first nuclide and a second sub-coil array of a second nuclide, wherein the two combined nuclides, the first nuclide and the second nuclide are different from each other;
the first sub-coil array comprises a plurality of first coil units, the second sub-coil array comprises a plurality of second coil units, and the second coil array comprises a plurality of third coil units,
wherein each of the plurality of first coil units, each of the plurality of second coil units and each of the plurality of third coil units respectively transmit different nuclide signals, a center line of each of the plurality of second coil units coincides with a center line of a corresponding third coil unit, a center line of each of the plurality of first coil units is shifted relative to a center line of the corresponding third coil unit.
