Abstract: This disclosure includes magnetic field correction devices and methods for using the same. In particular, some magnetic field corrections devices include an arch-shaped body configured to be worn outside of a user's mouth such that the arch-shaped body follows a contour of the user's face; and where the arch-shaped body comprises one or more sidewalls configured to be coupled to a plurality of members comprising magnetically permeable material. Other embodiments employ a forehead support, frame, and one or more straps coupled to an arch-shaped body. Other embodiments employ a hybrid of intraoral and external embodiments.

Abstract: This disclosure includes magnetic field correction devices and methods for using the same. Some magnetic field correction devices include an arch-shaped body configured to be worn inside or outside of a user's mouth such that the arch-shaped body follows the contour of the user's teeth or face, where the arch-shaped body has one or more sidewalls and where the sidewalls are configured to receive a plurality of ferromagnetic or magnetic members. Some of the present methods include performing magnetic resonance imaging (MRI) on a user having one or more magnets coupled to an apparatus disposed inside or outside and adjacent to the user's mouth. Others of the present methods include coupling a plurality of magnets to an arch-shaped body configured to be worn by a user, where the magnets are configured to reduce artifacts caused by non-biological materials within the user's mouth during MRI.

Abstract: An array coil to achieve more uniform RF excitation for high field magnetic resonance imaging. In the preferred embodiment, the array coil has a plurality of transmit-composite elements distributed around the object to be imaged. A composite element comprises up to three current loops preferably orthogonal to each another. The array coil has the capability to shape the distribution of all three orthogonal components (x, y, and z) of the RF B1 field.
