An accurate modeling of a constructed coil contains resistive and mutual inductance coupling and preamplifier de-coupling information in realistic electromagnetic fields and is important for optimization of SNR and g-factor. Noise correlation analysis and current ratio of induced current relative to the primary current at different angular position representing different coupling have been used to evaluate the perturbation in the B/E- field distribution. Our results suggest that incorporating a preamplifier circuit into the coil model can accurately simulate
