Abstract
A metamaterial liner for an MRI bore. The metamaterial liner may cover only a portion of the MRI bore, allowing travelling wave excitations within the lined portion. By restricting the waves to the lined portion, improved signal to noise ratio may be provided. The lined length may be adjustable, for example by forming the metamaterial liner of removable annular segments. A method is provided of adjusting the length of the lined portion by removing metamaterial segments. The segments may be included in interchangeable modules. The MRI liner is suitable for any magnetic field strength, and in particular may provide improved signal to noise at reduced technical difficulty at magnetic field strengths between conventional field strengths suitable for a birdcage coil and conventional travelling wave field strengths.
