| To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, containing 46 different resolved tissues with their relevant electrical properties over 1Hz-100 GHz, non-ionizing electromagnetic radiation. The model is based on whole-body magnetic resonance images (MRI) of Zubal-phantom data with voxel dimensions of 3.6 mm. Wideband simulations are performed to show the successful application of the model in computational dosimetry. The results of the electric field calculation indicate that the peak of electric field in the body occurs at around 70 MHz, which is the same as the well-known resonant frequency of the body. Moreover, the difference between electric field intensity among tissues can be as high as 30 dB, and that tissues with lower water content (e.g. bones, knee) can generally have higher induced electric fields. High water content tissues such as the eye vitreous humor have generally lower induced electric fields. The model is available free of charge for research purposes at bioelectromag.ir. | ||
