Abstract:
This paper investigates the internal electric and magnetic
field distribution and the specific absorption rate (SAR)
values in a magnetic resonance imaging-based model of the inner
hearing system exposed to 900 and 1800 MHz. The internal fields
distributions were calculated using the Finite Integration Technique.
The estimation of the field values was evaluated along lines
passing through that target organ, specifically from the vestibular
to the cochlear region and from the apex to the base of the cochlea.
The specific findings are: 1) higher internal fields strength and SAR
value in the vestibular region rather than in the auditory region,
especially for the inner ear closer to the external source; 2) higher
internal fields strength in the basal and apical region of the cochlea
than in the middle one; 3) local differences in the internal fields
distribution and SAR value, comparing the head models including
or not the inner auditory system model; 4) results’ variability
evaluated by changing the head-source mutual position and the
dielectric properties of the inner hearing system.
