Magnetic resonance double-frequency birdcage coil and related equipment

The invention relates to a magnetic resonance double-frequency birdcage coil and related equipment. The magnetic resonance double-frequency birdcage coil comprises a first end ring; the second end ring is separated from the first end ring in the axial direction and comprises N first LC parallel resonance circuits which are sequentially arranged in the circumferential direction and are connected in series, and the resonance frequency of the first LC parallel resonance circuits is the first frequency; the third end ring is separated from the second end ring in the axial direction and located on the side, away from the first end ring, of the second end ring; the N supporting legs are sequentially arranged between the first end ring and the third end ring at intervals in the circumferential direction, each supporting leg comprises a first part connected with the first end ring and the second end ring and a second part connected with the second end ring and the third end ring, the first part comprises a second LC
