✦ Synopsis

Abstract

A mathematical model is developed for the numerical analysis of birdcage coils constructed using capacitors having different capacitance. With the aid of this model, it is shown that the deviation of some capacitance introduced by tune, balance, and drive mechanisms can cause inhomogeneity in the B~1~, field produced by the coil. Useful curves and formulae are developed to provide a guideline for the design of birdcage coils.

A birdcage coil possesses various intrinsic resonant modes. One of the modes produces sinusoidal current distribution around the rung elements of the birdcage and generates a highly uniform B 1 field in the transverse plane. Another mode is the end-ring resonant mode, in which there are no currents
