Abstract:
1. A millipede surface coil having electrically conducting elements fixed to a surface of a sheet of an insulating material and connecting to an MRI apparatus via transmission lines, said coil comprising: a first conducting end strip disposed on the surface of the sheet of the insulating material; a second conducting end strip disposed on the surface of the sheet of the insulating material parallel to said first conducting end strip; and a first set of parallel conducting rung elements disposed between first and second conducting end strips, fixed to the surface of the insulating material and electrically connected to said first conducting end strip; a second set of parallel rung elements, each being placed between a pair of conducting rungs of said first set, fixed to the surface of the insulating material, and electrically connected to said second conducting end strip, wherein a number of parallel conducting rung elements and a spacing between adjacent rung elements are selected to provide dominant inductive and self-capacitance values to resonate the millipede surface coil at a desired operating frequency, said number of parallel conducting rung elements not interrupted by one or more lumped capacitor elements.
