Abstract :
A novel two-dimensional ladder network resonator design is introduced for signal transmission and detection in magnetic resonance imaging. It is shown that planar structures consisting solely of inductively coupled elements have a high-pass eigenmode spectrum and exhibit eigenfunctions which can be used for magnetic resonance imaging, including quadrature operation. Two 5 times 5 element prototypes, a planar surface coil and a volume head coil, are presented to demonstrate the suitability of the design for imaging at 3.0 Tesla
