Abstract
An MR loop coil design incorporates a balun into the loop coil. With this approach, some components of the coil may be simultaneously part of the imaging coil and the balun. Further, with this approach the number of components used to build an MR coil may be reduced, which may result in a reduction in cost, weight and size. This MR loop coil design may also be used to build phased array coils from the smaller loop size. Such an approach may use small feeder circuit boards oriented generally perpendicular to the coil elements to reduce interactions between the feeder boards and the coils. Such feeder boards may also be made smaller than conventional feeder circuits because the integrated balun coil design may reduce the number of components needed to create balanced coils in the array.
