A study of in
vivo radiofrequency exposure of a group of human models to a reduced set of
birdcages that cover clinical scanner variability was performed at 64 MHz,
with a view to the assessment of implant safety during magnetic resonance
imaging. Finite-difference time-domain simulations were run for combinations of
human model/landmark/birdcage for quadrature fed coils representing closed-bore
systems with respect to RF exposure. The evaluation of the E-fields for the Tier 3 of TS109741
shows large variations in the tangential E-field values obtained with the
different coils.
