We devised a numerical model of a 123.2MHz 32-rung high-pass whole-body birdcage coil of the Siemens 3T Connectom scanner. The model was developed based on realistic geometrical data for most of coil elements and a reverse engineering approach. Our simulations suggest that RF exposure at level of 3.2W/kg head SAR may result in higher than 20W/kg of SAR10g in the Connectom scanner; (ii) B1+ mapping alone cannot be used for validation of numerical model of whole-body birdcage coil, (iii) developed RF-circuit and 3D-EM co-simulation approach with reverse engineering resulted in a reasonable agreement between simulations and measurements in human subject.
