3-D RF Coil Design Considerations for MRI

Abstract

High-frequency coils are widely used in medical applications, such as Magnetic Resonance Imaging (MRI) systems. A typical medical MRI includes a local radio frequency transmit/receive coil. This coil is designed for maximum energy transfer or wave transfer through magnetic resonance. Mutual inductance is a dynamic parameter that determines the energy quantity to be transferred wirelessly by electromagnetic coupling. Thus, it is essential to analyze the self and mutual inductances of this coil. Other parameters, including electromagnetic shielding, frequency, and distance, which influence voltage and power transfer are investigated here. Theoretical formulas and simulation models proposed in the present paper are implemented by using MATLAB and ANSYS MAXWELL and ANSYS SIMPLORER Finite Element (FE) packages for determining the performance and properties of the coil. So, the main goal is evaluating of software steps that simplify the design of RF resonance circuits. Also, experimental results are given for the validation of the proposed method. Consequently, Safety and efficiency are automatically maximized by following the best design considerations.
