Determining current distributions for RF resonators in magnetic resonance imaging

Abstract

Two new methods are presented for computing the current distribution within curved, finite width conductors arranged around the circumference of a circular cylinder. The number of these conductors is allowed to be arbitrary. The width and the overall current flowing in each conductor is also allowed to be specified. Results for a test case are demonstrated and the current distribution for a radio-frequency probe used in magnetic resonance imaging is computed. The fields produced by the probe are also determined and compared with experiment.
