Motivation: Evaluating induced temperature rise (ΔT) in human tissue at a hot spot.
Goal(s): Comprehensive analysis of ΔT by examining cases where SAR0.1 g (SAR, specifically averaged over a mass of 0.1 gram of human tissue) remains constant but the spatial distribution of SAR inside and outside the averaging volume is different.
Approach: Analytical solutions were obtained for estimating ΔT as a result of the SAR distribution exhibiting spherical symmetry with both uniform and Gaussian distributions.
Results: Using SAR0.1g without consideration of the distribution of SAR within and outside the enclosed volume cannot be a reliable tool for estimation of ΔT.
Impact: We have obtained analytical results on the effect of the SAR distribution on the conservatively estimated ΔT in different RF exposure scenarios.
