This work describes a simple but efficient intraoral radiofrequency coil, positioned between the upper and lower jaws in the occlusal plane, with efficient utilization of B1 field for imaging teeth and associated structures. We used a regular single loop surface coil with plane of coil oriented orthogonally to Zeeman field. We found that the sensitive volume of coil in this position includes the most important dental structures, while partially excluding the cheeks, lips and tongue that have less informative but very intense lipid signals. We present simulated data and images showing advantages of using such coil for dental applications.
