The elimination of inductive coupling is a very important step for the use of RF coils arrays in parallel imaging. In the present work, a 4-channel RF coil array for the rat head was designed and built at 7T to use inductive decoupling of the different channels. It shows good performance with excellent isolation of all channels and immunity to standing waves or other parasitic signals, and utilizes high input impedance preamplifiers, which are easier to build and less sensitive to mutual inductance coupling between the RF coils.
