Abstract
A system and method for magnetic resonance imaging (MRI) and static field (B0) shimming. A coil system includes a conductive loop configured to be arranged proximate to a region of interest (ROI). The coil system also includes an alternating current (AC) circuit electrically connecting the conductive loop to an AC electrical connection configured to be coupled to an MRI system to communicate medical imaging signals received by the conductive loop from the ROI during a medical imaging procedure to the MRI system. The coil system further includes a direct current (DC) circuit electrically connecting the conductive loop to a DC electrical connection configured to be coupled to a DC power source and a plurality of circuit components configured to block DC signals from reaching the AC electrical connection in order to produce a spatially varying static magnetic field for shimming inhomogenieties of the static field.
