Abstract:
We evaluated the influence of 3T magnetic resonance imaging whole body birdcage coil modeling on electromagnetic exposure estimation using a human model. Simplification of coil geometry, realistic tuning and capacitor losses had a relevant impact on the estimated electric distributions. Variety of the generated electric field has to be carefully considered for reliable RF safety assessment of a patient with a passive or active implant undergoing magnetic resonance imaging.
