Abstract: The parallel imaging technique is widely used in 7T MRI scanners. It employs multichannel RF coil arrays to apply a concurrent excitation and acquisition method. Concurrent excitation faces significant challenges in terms of electromagnetic coupling between the RF coil elements. In order to prevent interference between the RF coil elements’ exciters, several decoupling methods have been developed to compensate for coupling and to permit independent work for the exciters. This paper studies the coupling between meander coils arranged in two different geometrical setups and investigates the isolation performance between the coils by applying two different decoupling networks depending on the geometrical setup of the coils. These two decoupling networks in addition to a T-shaped decoupling network have been integrated into a Tx/Rx body coil for 7 T to compensate for mutual coupling between array coil elements. The results have been obtained by using CST Microwave Studio (CST AG, Darmstadt, Germany).
