Abstract

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 (B0) 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 (B0) to align an axis extending through a loop of the coil with the B0 direction 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 (B1). The image data is reconstructed to create an image of the ROIs.
