Abstract :
A challenging problem in computational electromagnetics is the prediction of the electromagnetic fields induced in a human body by radiation from nearby antennas. Interest in possible biological effects of portable telephones has spurred recent work on this problem. Currently the most popular approach for making these calculations is the finite difference time domain (FDTD) method. In order to provide more accurate estimates of electromagnetic fields inside a human body more realistic FDTD meshes have been obtained from MRI scan data. An alternative approach for obtaining the human body data is the Visible Human Project. This project involved slicing a frozen cadaver in 1 mm intervals, photographing the slices, and digitizing the data.
