B1 uniformity improvement of a birdcage coil with a chain mail configuration

Motivation: The main goal is to enhance the performance of an RF coil used in preclinical MRI imaging, specifically at a field strength of 7 T. Goal(s): The researchers proposed a modification to a standard birdcage (BC) coil. This modification involves adding a "chain mail layout" to the rungs of the coil. Approach: The idea for the chain mail layout was inspired by previous low pass wiring schemes used in chain mail coils, as reported by Mansfield. Chain mail refers to a type of flexible armor composed of interlinked metal rings. Results: Phantom images were acquired and used to compute uniformity profiles. Impact: These results obtained with the chain mail BC coil contributes to our overarching goal of achieving improved MRI coil performance for preclinical applications at 7 T.
