    摘要： A method of magnetic resonance is provided that uses a frequency swept excitation wherein the acquired signal is a time domain signal is provided. In one embodiment, the method comprises, applying a sweeping frequency excitation and acquiring a time domain signal. The sweeping frequency excitation has a duration and is configured to sequentially excite isochromats having different resonant frequencies. Acquisition of the time domain signal is done during the duration of the sweeping frequency excitation. The time domain signal is based on evolution of the isochromats.

    摘要： 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 ROls, the ROls 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 ROls. A pulse sequence is then performed with the MRI system and the RF coil to acquire imaging data from the ROls simultaneously while using a transverse component of an excitation field (B1). The image data is reconstructed to create an image of the ROls.
