FEM Based Design and Simulation Tool for MRI Birdcage Coils Including Eigenfrequency Analysis
Designing a Radio Frequency (RF) birdcage coil used in Magnetic Resonance Imaging (MRI) at high frequencies where the wavelength is comparable with the coil dimensions is a challenging task. Before construction of the coil, not only calculating the capacitance value which is necessary for the coil to resonate at the desired frequency but also geometrically modeling the coil in a 3D simulation environment and making electromagnetic analysis inside the coil have importance in terms of observing the resonance behavior and other performance features of the coil. This study covers both design and simulation methods of low-pass and high-pass birdcage coils in COMSOL Multiphysics and the software tool developed to perform these design and simulation methods according to user-specified parameters.
