Accurate Evaluation of RF Coil-tissue Interactions Using a Hybrid FDTD-MoM Method
نویسندگان
چکیده
A comprehensive consideration of loading effects is essential to the design/analysis of high-frequency MRI radio frequency (RF) coils. In this study, a hybrid finite difference time domain (FDTD)-method of moments (MoM) simulation method is implemented for the accurate evaluation of RF coil-tissue interaction. Using this approach, the RF coil is modelled using the MoM algorithm, and the biological load is handled with the FDTD algorithm. Effective communication between these two approaches is realized through a Huygence equivalent surface. The algorithm has been successfully validated and applied to a loaded coil study and the simulation demonstrated the potential of the hybrid algorithm for high frequency RF coil designs.

Numerical Evaluation of an 8-element Phased Array Torso Coil for Magnetic Resonance Imaging
Recently, parallel imaging using multiple RF coils has excited great interest in magnetic resonance imaging (MRI). To help the design of some novel flexible array coils for the human torso, we theoretically investigate the RF field of an 8-element array coil loaded with an anatomically accurate model of the human torso. The RF behaviour is predicted based on a hybrid FDTD/MoM approach. The prim...

In a multimodal volume coil, only one mode can generate homogeneous Radiofrequency (RF) field for Magnetic Resonance Imaging. The existence of other modes may increase the volume coil design difficulties and potentially decreases coil performance. In this study, we introduce common-mode resonator technique to high and ultrahigh field volume coil designs to reduce the resonant mode while maintai...

The ability to predict both transmit and receive characteristics in vivo is an important and necessary tool for the development of coils especially at ultra high magnetic fields (UHF). Accurate simulation permits the virtual development of coils saving both human and material resources [1, 2]. This is especially important during this period where large arrays and complex geometries are being pr...
