Dosimetric studies involving in the experiments for the evaluation of the brain activation by LTE exposure

This paper presented the dosimetric studies in the research for evaluating the relationship between the LTE exposure and the brain regional activation. Measurement was made for the net power delivered to the dipoles for each exposed volunteer. During the exposure experiment, the exposed power was strictly controlled to achieve a constant exposure dose for each person. The numerical head model of each volunteer was reconstructed basing on the MRI images. FDTD simulation was performed to calculate the realistic power distribution in different head regions for all the exposed volunteers. Effects with the existence of the EEG electrode and leads on the head during the exposure were taken into considered in term of local SAR and regional induced current to prevent abnormal results. The dosimetric results were therefore applied for LTE EMF exposure related brain activation research.
