Highly Efficient Inductively Coupled Double Resonant Surface Coil for Simultaneous 1H/19F PET-MRI

Christian Findeklee¹, Christoph Leussler¹, Daniel Wirtz¹, Jochen Keupp¹

A PET compatible ¹H/¹⁹F surface coil was realized by an adjustable dual resonant inductive coupling loop. This concept enables convenient and accurate tuning and matching across a wide variety of different loading scenarios. In addition, the inductive coupling mechanism integrates a cable trap function. Furthermore, the stray field of the feeding loop is exactly the same at both operating frequencies. The coil was designed such that it is merely transparent for PET imaging.
