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.
