Methods and Apparatus for Compensating Field Inhomogeneities in Magnetic Resonance Studies

摘要

One aspect of the present disclosure relates to a method or determining location(s) at which at least one magnetic article is to be positioned during a magnetic resonance imaging procedure of at least one subject. A magnetic field Bo is applied to a region that includes the at least one subject and does not include the at least one magnetic article. First magnetic resonance information about the region in response to the applied magnetic field BO is received. The first magnetic resonance information relates at least in part to one or more magnetic field inhomogeneities in the region. Based at least in part on the first magnetic resonance information, at least one first location proximate the at least one subject at which at least one paramagnetic article and/or diamagnetic article is to be positioned is determined, so as to at least partially compensate for the one or more magnetic field inhomogeneities.
