An analytic inverse method is presented for the theoretical design of toroidal transverse gradient coils. This coil structure is chosen based on previous results for a fully 3D current density solution of optimal geometry. A regularisation strategy with a minimum power constraint is used to obtain toroidal current densities, and the method is applied to the design of unshielded and shielded, whole-body and head coil gradient systems. Resultant coil winding sets are found to display high efficiency, low inductance, high gradient homogeneity and good force balancing.
