Synopsis
RF shields are key components of volume coils, but they may cause imaging distortions and the significant heating. The effects of different shielding strategies were evaluated for a birdcage coil used to image animals at 9.4T. Three shields with various thicknesses and two shields with different slot patterns were comparatively investigated ed in terms of performance and temperature rise during fMRI acquisitions.
