Abstract

To investigate both spectral and spatial domain characteristics of radio-frequency coils in magnetic resonance experiments, we have developed a new approach based on the method of moments. Instead of the conventional point-matching scheme, the loop testing function is used. Such a testing function decreases the complexity of computation and elevates the efficiency of simulation. With the proposed testing function incorporated with a pulse basis function based on coil geometry topology, performance of both surface coil and volume coil can be predicted with consistent results compared with experimental data
