A
multi-circular shim coil (MCSC), which consists of a set of localized circular
current coils, provides the flexibility to design and produce linear and
higher-order magnetic fields that compensate for a given B0
imhomogeneity both statically and dynamically. However, the concept of the MCSC
has currently been realized only for cylindrical base geometries. Here we
translated the concept of the MCSC to a biplanar geometry, and a planar-type
MCSC was designed and fabricated for an open, 1.0 T permanent magnet system. We
concluded that the planar MCSC is a useful devise to achieve field homogeneity
with reasonable accuracy.
