Abstract
The present disclosure reports on a method to first determine the required electromagnetic stream function, and then iterate on the contouring of the stream function to optimize the force, torque, shielding, and/or mutual inductance of the design after-the-fact without compromising the electromagnetic performance and an electromagnetic coil manufacture according to the method. These parameters are sensitive to the precise positioning of the discrete wires.
Claims19
A method of manufacturing an electromagnet coil for use in a magnetic resonance imaging (MRI) system, the steps of the method comprising:
- forming a coil representation of a coil surface for the electromagnet coil;
- setting a plurality of performance metric requirements for a plurality of corresponding performance metrics for the electromagnet coil;
- defining a performance functional based on the performance metrics and a discretized coil representation;
- optimizing the performance functional based on the plurality of performance metric requirements, by varying a contour spacing and contour offset of the discretized coil representation;
- generating an updated discretized coil representation over the coil surface based on the optimized performance functional;
- and
- obtaining coil windings from the updated discretized coil representation.
