1. A conductive coil assembly for a magnetic resonance imaging (MRI) system, comprising:
a substrate;
a first hollow conductor coil; and
a second hollow conductor coil, wherein the first hollow conductor coil and the second hollow conductor coil are both disposed on the substrate relative to each other in an interleaved spiral pattern, and wherein respective interiors of both the first hollow conductor coil and the second hollow conductor coil are configured to receive and to circulate a coolant to cool the conductive coil assembly, and wherein the first hollow conductor coil comprises a first coiled portion defining a first series of increasing radius loops, the second hollow conductor coil comprises a second coiled portion defining a second series of increasing radius loops, the first coiled portion defines a coiled portion boundary, and the second coiled portion is located within the coiled portion boundary.
