We are presenting a method for decoupling strip line elements in RF volume coils for high field (7T) Parallel imaging. Previous transceiver coils have relied on the strip line elements containing most of the magnetic field within the strip line by reducing the strip/ground plate separation, or by including a material with high dielectric properties. This solution limits coupling by restricting the B1 penetration. Using experimental and finite element modelling we have shown that strip line elements can be completely decoupled without detuning the elements by placing an inter-element decoupling strip in an optimum position, without restricting RF penetration.
