Comparative Study of MRI coils Design for MRI Imaging System
2025
Overview
In this article, we survey a complete MRI systematic pipeline from theoretical modelling and numerical simulations to analysis and optimization of three different types of MRI coils. After a preliminary parametric exploration using generic models based on standard equations, a Method of Moments (MoM) study of geometrically representative coil structures was conducted to explore the nearer field effects. Then, Finite Difference Time Domain (FDTD) analysis was performed to realize the optimized-designed devices to be fabricated using MEMS process and confirmed its performance by using Vector Network Analyzer (VNA) and an anechoic chamber measurement. Performance comparisons based on parameters like resonance frequency, gain and radiated power were performed. Then for the Roger’s 6010TM RT/Duroid substrate material (ε=10.5) thickness 1.6 mm, the rectangular resonance frequency and return loss for the MRI coil are 8.06 GHz and 52.73 dB respectively. The gain on this coil is 36.45 dBm and the radiated powers were 59.25 dBi and 53.56 dBi. In comparison, using similar substrate material, it obtained a return loss of 52.73 dB and a gain of 45.89 dBm, while the circular MRI coil works at the same resonance frequency and could be found in the literature. Using Teflon-PTFE substrate with dielectric constant of 2.1, the resultant triangular MRI coil is fabricated which shows resonance frequency of 8 GHz return loss of 45.81 dB and gains of 49.35 dBm. This study’s performance metrics are closure with regularization results, and the closure is the validation of the enhanced performance of the proposed resonators for medical imaging applications. The designs were also extrapolated to bio-phantom models for further exploration. These RF coils could improve MRI diagnostic technologies as confirmed by the electromagnetic simulation results.
