Abstract
In one aspect, in a magnetic resonance imaging system having a gradient coil array comprising a plurality of independent coils distributed about an enclosure, a method of applying currents to said coils is disclosed, which comprises defining a merit function for optimizing at least one feature of any of a magnetic field and an electric field generated by the coils, using a computer processor to optimize the merit function so as to determine an optimal current vector, wherein said element of the current vector provides a current value for application to one of said gradient coils, and applying the currents to said coils.

A system for magnetic resonance imaging (MRI), comprising:
- a gradient coil array comprising a plurality of independent coils distributed about an enclosure,
- a controller configured to actuate said plurality of coils to generate a magnetic field within a volume of interest,
- wherein said controller is configured to optimize a merit function defined for optimizing at least one feature of any of a magnetic field and an electric field generated by said coils so as to determine an optimal current vector containing current values for application to said coils,
- a plurality of amplifiers in communication with said controller, each of said amplifiers being electrically coupled to one of said independent coils,
- wherein said controller effects each of said amplifiers to apply a current defined by said current vector for a coil associated with said amplifier to said independent coils.
