Abstract:
1. A radio frequency (RF) birdcage coil comprising: a first distributed capacitance end ring; a second distributed capacitance end ring; and a plurality of rungs connected between the first and second distributed capacitance end rings, wherein at least one of the first and second distributed capacitance end rings includes a substrate having a first side and a second side, a first plurality of conductors formed on the first side as outermost conductors, a second plurality of conductors formed on the second side, and an insulating layer deposited on the first side such that the insulating layer substantially covers an upper surface of the first plurality of conductors that faces away from the substrate in order that the first plurality of conductors are sandwiched between the insulating layer and the substrate in order to reduce a likelihood of unintentional arcing.
