Abstract: The embodiments disclosed herein relate generally to magnetic resonance imaging systems and, more specifically, to the manufacturing of a gradient coil assembly for magnetic resonance imaging (MRI) systems. For example, in one embodiment, a method includes ultrasonically consolidating a plurality of sheets of a conductive material to form a consolidated structure and machining one or more conductive channels into the consolidated structure to form an inductor.

CPC classification number: G01R33/3875

Abstract: Embodiments of the invention are utilized to improve shimming capability while reducing radial space and the volume required to contain active shim coils by nesting the coils of different degrees and orders inside each other and limiting the azimuthal span of the individual saddle coils. This allows two or more radial shim sets to be combined together in the same layer resulting in a significant radial savings that increases the useable portion of an MRI system.
