Magnetic resonance imaging radio frequency coil assembly for oral cavity

The utility model relates to a magnetic resonance imaging radio frequency coil assembly for an oral cavity. The magnetic resonance imaging radio frequency coil assembly comprises coils arranged inside and outside the oral cavity respectively. The inner coil comprises two layers of resonance circuits which can be attached to the inner surface and the outer surface of an alveolar cavity respectively, a resonance cavity space with the good radio frequency field uniformity is constructed, and the filling factor and the quality factor of the radio frequency coil are improved. The outer coil is fully attached to a main face area corresponding to an alveolar cavity, and compared with a traditional head body coil, the filling factor and the quality factor can be improved. The inner coil serves as an induction coil and is not provided with a feed port, the outer coil is provided with a feed port to be connected with a magnetic resonance system to achieve the transceiving function, and the inner coil and the outer coil
