Abstract :
An optimization technique for magnetic resonance imaging gradient coils is presented. Assuming the coil in the form of four windings, each having a spiral polygon shape, the coordinates of nodes are varied to optimize the coil performance. The hybrid simulated annealing - Powell technique is used as the numerical tool. Results of calculations for differently formulated goal functions are demonstrated
