The present invention relates to a method of discretization of the
continuous current solution of a gradient coil design that allows
satisfaction of the target field quality characteristics as well as other
characteristics such as minimization of the energy/inductance,
minimization of the residual eddy current effect, minimization of the
thrust forces on the coil and cold shields, coil resistance thus the
power dissipated by the coil, etc. The method of optimized gradient coil
design can be applied to the design of axial or transverse gradient
coils. The method of this invention includes the steps of defining at
least one, and more commonly numerous performance characteristics of the
desired gradient coil, concurrently varying discretization parameters to
develop numerous possible hypothetical gradient coil designs, evaluating
the designs to determine whether the defined performance characteristics
are met by each design and selecting one design.
