This work proposes an approach to analysis the equivalent noise resistance, including coil self-resistance, of surface coils of low field MRI and small volume coils of extra high field MRI using the finite element method. The simulation and imaging results suggest that the finite element method is feasible to analyze surface coils of low field MRI and small volume coils of extra high field MRI. The coil self-resistance accounts higher percentages of the equivalent noise resistance of surface coil whereas it is comparable with the sample resistance of animal coils which are integrated with animal holder.
