Abstract: The present invention provides a method for structurally designing that article of manufacture and a constructed and operational article of manufacture that will allow the inclusion of minimally coupled higher order/degree shim coils in any magnetic resonance apparatus. The novel system and methodology includes determining the shim coil terminal voltage without any prior or advance knowledge of the configuration of the electrical windings of the imaging gradient coil that is inducing that voltage.

Abstract: The present invention is a portable in-bore shim coil insert suitable for correcting high-degree and high-order magnetic field inhomogeneities over a limited examination zone in a magnetic resonance assembly operating above 3 T magnetic field strengths, wherein the magnetic resonance assembly includes at least a MRI magnet having an internal bore of known configuration and volume, at least one set of gradient coils, and an arrangement of radio frequency coils. The in-bore shim coil insert and corresponding method of use is able to produce higher degree and order shimming effects on-demand (i.e., the correction of at least some 3rd to 6th degree field terms or inhomogeneities) and will markedly improve the quality of in-vivo magnetic resonance spectroscopy and/or imaging of any desired anatomic site, i.e., any or all of the various organs, tissues, and systems present in the body of a living subject.
