Design of shielded quadrupolar gradient coils for magnetic resonance microscopy by simulated annealing

摘要

A novel design for shielded, magnetic pulsed field gradients with transverse geometry is presented. The gradients are intended for use in NMR microscopy and localized spectroscopy. The integrated coil design is based on simulated annealing (SA) optimization and results in well shielded coil sets of high linearity and sensitivity. The design approach is a flexible one and is amenable to the design of gradients in a variety of configurations.
