A new method for comparing simulated electromagnetic field results of local receive antennas to measured SNR images is shown. Electromagnetic field simulation is a powerful tool for designing MR antennas. Simulation results cannot be compared directly to measured SNR images due to system properties like e.g. magnetization of the investigated sample or receiver bandwidth. The new calibration method allows a quantitative comparison of simulated field results to measured SNR images of an arbitrary antenna structure. In this work the theory of this method is given and results are shown with an example of a 4-element antenna array.
