In this tutorial paper, we describe some basic principles and practical considerations for designing probe circuits for NMR or MRI. The goal is building a bridge from material that is familiar from undergraduate physics courses to more specialized information needed to put together and tune a resonant circuit for magnetic resonance. After a brief overview of DC and AC circuits, we discuss the properties of circuit elements used in an NMR probe and how they can be assembled into building blocks for multi-channel circuits. We also discuss the use of transmission lines as circuit elements as well as practical considerations for improving circuit stability and power handling.
在本教程论文中,我们描述了用于核磁共振(NMR)或磁共振成像(MRI)的探头电路设计的一些基本原理和实际考量。目标是搭建一座桥梁,将本科物理课程中熟悉的内容与组装和调谐磁共振谐振电路所需的更专业信息联系起来。在简要概述直流和交流电路之后,我们讨论了NMR探头中使用的电路元件的特性,以及如何将它们组装成多通道电路的模块。我们还讨论了将传输线用作电路元件以及提高电路稳定性和功率处理能力的实际考量。
