Stochastic sensitivity in thermal dosimetry for the homogeneous human brain model

Abstract

The sensitivity analysis of thermal parameters in the homogeneous human brain model is presented, investigating their influence on thermal rise, as a direct consequence of the high frequency exposure. The novelty presented is the combination of modern Stochastic Collocation method with the thermal part of the existing deterministic electromagnetic-thermal model. The sensitivity analysis excludes the less important parameters and can be used as a prior step of more complex experimental or computational models. In addition, obtained confidence margins give more precise estimate if temperature elevation reaches the prescribed limits or not.
