A multi-planar intraoral radio frequency (RF) coil apparatus for use in a magnetic resonance imaging system can include a housing having a shape configured to be positioned in an occlusal plane between an upper jaw and a lower jaw of a subject and a plurality of coil elements disposed within the housing. The plurality of coil elements includes a first coil element positioned in a first plane and a second coil element positioned in a second plane different from the first plane and substantially parallel to the first plane. The coil elements can be loop coil elements or dipole coil elements.

Multi-planar intraoral RF coil for magnetic resonance imaging

A system and method for producing an image using a radio frequency (RF) coil in a magnetic resonance imaging system (MRI). A static magnetic field (B) extends across a first and second region of interest (ROI). A local radio frequency (RF) coil, shaped like a dental arch, is positioned proximate to the ROIs, the ROIs being the upper and lower jaw of a subject. The RF coil and the subject are oriented in the static magnetic field (B) to align an axis extending through a loop of the coil with the Bdirection of the static magnetic field extending across the ROIs. A pulse sequence is then performed with the MRI system and the RF coil to acquire imaging data from the ROIs simultaneously while using a transverse component of an excitation field (B). The image data is reconstructed to create an image of the ROIs.
