Zusammenfassung:The invention relates to an application of a radio frequency coil for tooth magnetic resonance imaging. The radio frequency coil comprises an inner radio frequency coil, or an outer radio frequency coil, or a combination of the inner radio frequency coil and the outer radio frequency coil. The internal radio frequency coil comprises two layers of resonance circuits which can be attached to the inner surface and the outer surface of the alveolar cavity respectively, a resonant 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 external radio frequency 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. When the inner radio frequency coil and the outer radio frequency coil are used in a combined mode, the inner coil can serve as an induction coil without a feed po
