Abstract
A method of manufacturing an electromagnet coil for use in a magnetic resonance imaging (MRI) system includes: generating a coil surface representation defining a surface to contain the electromagnet coil; defining a set of performance metric functions, the set including a mutual inductance function defining mutual inductance between the electromagnet coil and a second electromagnet coil; defining a performance functional based on the coil surface representation and the set of performance metric functions; optimizing the performance functional; generating a current density pattern over the coil surface representation based on the optimized performance functional; and obtaining coil windings defining the electromagnet coil from the current density pattern.
