A priori imposed discrete topology considerations in designing transverse resistive shim coils

Transverse gradients and shims have always represented a challenge to design and build. The target field method has revolutionized the design of such coils. Still, many approximations had to be considered, such as truncating the secondary windings, choosing the constraint points for the target field (for high-order tesseral shims this is especially difficult), and discretizing continuous current density distributions. The field qualities found for the continuous case may become altered when real wires are used. A new approach is applied to the design of resistive transverse shims in order to address these difficulties.
