O objetivo deste estudo é desenvolver um novo método de estimativa da taxa de absorção específica (SAR) média de corpo inteiro com base na técnica de varredura de campo cilíndrico externo. Esta técnica é adotada com o objetivo de simplificar a estimativa dosimétrica de fantomas humanos que possuem diferentes posturas ou tamanhos. Um sistema de modelo experimental em escala é construído. A fim de examinar a validade do método proposto para modelos humanos realistas, discutimos os prós e contras das medições e análises numéricas baseadas no método de diferenças finitas no domínio do tempo (FDTD). Consideramos os fantasmas anatômicos humanos europeus e as ondas planas na faixa de frequência de telefonia móvel de 2 GHz. Os resultados médios de SAR medidos de corpo inteiro obtidos pelo método proposto são comparados com os resultados das análises de FDTD.

Abstract: The aim of this study is to develop a new whole-body averaged specific absorption rate (SAR) estimation method based on the external-cylindrical field scanning technique. This technique is adopted with the goal of simplifying the dosimetry estimation of human phantoms that have different postures or sizes. An experimental scaled model system is constructed. In order to examine the validity of the proposed method for realistic human models, we discuss the pros and cons of measurements and numerical analyses based on the finite-difference time-domain (FDTD) method. We consider the anatomical European human phantoms and plane-wave in the 2 GHz mobile phone frequency band. The measured whole-body averaged SAR results obtained by the proposed method are compared with the results of the FDTD analyses.
