An evaluation of the present approach to the design of birdcage RF coils for RMI, based on periodic lumped circuit, has been performed. It appears that, for coils bigger than λ/6, a more accurate model is required, to reduce the trial-and-error tuning of the coil.

Abstract
An evaluation of the present approach to the design of birdcage RF coils for RMI, based on periodic lumped circuit, has been performed. It appears that, for coils bigger than λ/6, a more accurate model is required, to reduce the trial-and-error tuning of the coil.
