A novel transceiver array composed of monolithic
transmission line resonators, fabricated on flexible
substrate, for MRI at 7 T is presented. Individual array
elements are mutually decoupled via overlapping annexes;
inductive matching and fine-tuning using pick-up loops
in over-coupled mode was implemented. The decoupling and
parallel imaging performance of the array was assessed
in bench and MRI experiments in terms of transmission
S-parameters, noise correlation values and GRAPPA
g-factors, comparing planar and bent array
configuration. It is shown that the developed array may
be form-fitted to non-planar samples without degrading
its performance.
