The design of biplanar, shielded, minimum energy, or minimum power pulsed B0 coils.
By extending the formalism previously developed for the design of unshielded, biplanar gradient coils, shielded biplanar B0 coils optimized for homogeneity and either minimum energy or minimum power may be designed. We present results from an integrated approach to shielded biplanar coil design, the results of which are also applicable to gradient coils, enabling the design of shielded coils with a concomitant decrease in total inductance of the coil. Length constraints are also included in the integrated minimization procedure. Results from a preliminary design indicate that high-homogeneity, low-impedance, well-shielded coils result from this design approach.
