Abstract

The electromagnetic properties of a new volume resonator coil for MR neuroimaging are studied. This coil design is based on a resonator coil called PERES coil. A commercial software tool based on the finite-element method is used to compute the electric and magnetic fields for the quasi-static regime for a specific layout of two coils with 4 rectangular-shaped coils each. Computational experiments were done to calculate the optimal number of nodes and elements in the mesh. This commercial software tool allows us to clearly visualize the electromagnetic properties of the coil as a function of a particular configuration
