Abstract
In MRI, gradient coils are needed for spatial selection and position coding to obtain the position information of the NMR signal. In this paper, a new design scheme for actively-shielded x, y-gradient coils, namely, a minimum-power and/or minimum-inductance design scheme using current-loop elements, has been proposed. Its utility in designing MRI gradient coils has been shown by using simulation. An actively-shielded x-gradient coil has been designed as an example and the results are presented. The design scheme seems to be useful for actively-shielded transverse gradient coils, even of non-cylindrical or of arbitrarily -selected shapes.
