Full wave simulations are known for their high accuracy, but simulation optimization is not feasible with FDTD and FEM for vast numbers of MRI coil applications. Optimization strategies do have feasible runtimes for quasi-static solutions, but the system being simulated must be small compared to the electromagnetic wavelength since they do not account for boundary conditions. This work uses multiple single loop coils of different diameters and three phantoms with a simple geometry to compare the accuracy and usefulness of full wave and quasi-static solutions of RF coils at 3T. Full wave simulations proved to be significantly more accurate.
