Volumetric wireless coil based on periodically coupled split-loop resonators for clinical wrist imaging.

Purpose: Design and characterization of a new inductively driven wireless coil (WLC) for wrist imaging at 1.5 T with high homogeneity operating due to focusing the B field of a birdcage body coil.

Methods: The WLC design has been proposed based on a volumetric self-resonant periodic structure of inductively coupled split-loop resonators with structural capacitance.
