Receive coil arrays are used in MR to maximize the Signal to Noise Ration (SNR) of measured signal. Engineers goal is to build such arrays with high filling factor using electrical components with minimal losses, and decoupled coil elements such that elements noise and noise correlation is reduced. In this work we experimentally show that the design a proper matching network is critical because the matching network is the first component in the receive chain. Simple one channel and two channels experiments were performed with the use of an Automatic Matching Network (AMN) system.
