Abstract
In the present invention a method is disclosed to correct the asymmetry in an NMR radio frequency coil of the type that has a pair of conductive loop elements disposed in a spaced apart relation along a common longitudinal axis. The coil has at least eight conductive elements electrically interconnecting the loop elements at point spaced along the periphery of each of the loops. A pair of corrective capacitive elements are placed 45.degree. apart from one another and in series with a pair of the conductive segments which interconnect the loops. The present invention also relates to an NMR radio frequency coil having N-fold symmetry and reduced eddy current.
