Ultrashort gradient coils for ultrashort cylindrical MRI systems require new design methods. The challenge is to reduce system length while maintaining performance, e.g., to maintain acceptable linearity and uniformity over a large field of view (FoV). Trading MR system performance to achieve short

✦ Synopsis
An application of the target field method to the design of shielded biplanar gradient coils for magnetic resonance imaging electromagnets is presented. Some specific cases are studied, and optimized geometries are proposed for the axial and transverse gradient coils that eliminate the third- and minimize the fifth-order terms in the magnetic field expansion.

A distributed coil design is described which employs active force shielding to reduce acoustic noise. Both axial and transverse gradients employ sets of distributed pairs of coplanar closed-arc loops whose planes are normal to the static magnetic field direction. The resulting gradients are also par
