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.
