论文摘要
本论文的主要贡献是研究磁感应层析成像(MIT)线圈中的皮肤和接近性效应,并为二维(2D)正向问题提供改进的模型。为了评估在可能的生物医学应用中改进方法的性能,对16个线圈2D MIT系统进行了建模,并采用了有限元方法(FEM)来解决正向问题。结果表明,从早期和改进的方法中获得的诱导电压之间的差异落在有意义的范围内,从改进的电导率对比方面。这一发现揭示了使用改进的正向方法为生物医学应用建模2D MIT线圈的重要性和必要性...
The main contribution of this thesis is to investigate the incorporating skin and proximity effects in magnetic induction tomography (MIT) coils and present an improved model for the two-dimensional (2D) forward problem. To evaluate the performance of the improved method in possible biomedical applications, a 16 coils 2D MIT system is modeled, and the finite element method (FEM) is employed to solve the forward problem. Results show the difference between the induced voltages obtained from the early and improved method falls into the meaningful range in terms of achievable conductivity contrast from the improved one. This finding revealed the importance and necessity of using the improved forward method for modeling 2D MIT coils for biomedical applications...
