We present a 32 channel lattice head array based on transmission lines for very high field. For this, a combination of concentric transmission line elements was pursued to demonstrate that they can be used both in parallel and perpendicular orientation to the magnetic field and to investigate whether an array consisting of a combination of both type of elements improves SNR and parallel imaging performance. Our results demonstrate that concentric arrangements of transmission line arrays are feasible at 7 Tesla and improve the achievable reduction factors significantly.
