Results of the pre-study for brain exposure investigation.

IV. = thermal; III. = slightly thermal; II. = most likely non-thermal; I. = non-thermal.*) relating to the double-cone waveguide with only 1 of the 6 exposure places occupied.**) Due to the varying results for different depths of the anaesthetical state only the range of the measured temperature elevation is given instead of mean and standard deviation.***) determined from measured average initial brain temperature elevation via SAR = c (ΔT/Δt)|t = 0 with c = 3854 J/(kg K) the specific heat capacity of brain tissue.
