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.
