SAR analysis using DICOM based voxel model

Three-dimensional Finite Difference in Time Domain (FDTD) method has been used to calculate Specific Absorption Rate (SAR) induced in the head and hand for a handheld mobile phone. Both the head and hand are modeled using Digital Imaging and Communication in Medicine (DICOM) based anthropomorphic phantom voxel data considering the electrical parameters of different anatomical internal structures of the human head and hand. SAR values obtained using DICOM based voxel model are compared with that obtained using Zubal phantom based model to verify the suitability of the proposed method. The proposed method can be used for person specific real time simulation of SAR.
