Nested coil configuration of active shims in MRI systems
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.
