ABSTRACT:
A method for producing a shim piece for a magnetic resonance imaging (MRI) magnet. The shim piece is used to form a shim of a magnet and is designed to suppress eddy currents in the shim created by the introduction of a gradient magnetic field. The shim piece is formed by a plurality of ferromagnetic rods placed side-by-side and surrounded by a dielectric material.
