Apparatuses and methods for cancellation of inhomogeneous magnetic fields induced by non-biological materials within a patient's mouth during magnetic resonance imaging
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.
