An analysis is presented of the interaction between a long cylindrical imaging coil, commonly called a low-pass birdcage coil, and a cylindrical sample. Predicted and measured values of coil Q are shown to compare well throughout the resonance spectrum of an experimental coil-sample system. The analysis may be used to calculate feed-point impedances and is easily extended to high-pass coils.
本文对一种通常称为低通鸟笼线圈的长圆柱形成像线圈与圆柱形样品之间的相互作用进行了分析。结果表明，在一个实验性线圈 - 样品系统的整个共振频谱中，线圈品质因数（Q）的预测值与测量值吻合良好。该分析可用于计算馈电点阻抗，并且很容易扩展到高通线圈。
