摘要

高磁场磁共振成像(MRI)系统通常使用短段传输线来产生和感应交变磁场。由于传输线的分布特性，产生的磁场是不均匀的。本文研究了串联电容器在改善磁场均匀性方面的应用。得到的磁场分布进行了解析估计和数值计算。结果与传统传输线线圈的实现进行了对比。

Improved field homogeneity for transmission line MRI coils using series capacitors

High field magnetic resonance imaging (MRI) systems often use short sections of transmission lines for generating and sensing alternating magnetic fields. Due to distributed nature of transmission lines, the generated field is inhomogeneous. This work investigates the application of series capacitors to improve the field homogeneity. The resulting magnetic field distribution is estimated analytically and evaluated numerically. The results are compared to a case of a conventional transmission line coil realization.
