Abstract
A numerical procedure to calculate the electromagnetic (EM) power deposition in two-dimensional models of cross sections in the human body is described. The procedure involves obtaining X-ray images of cross sections of specific areas with computer axial tomographic scans and then solving the EM boundary value problem by using the method of moments. The formulation thus takes into account not only the spatial distribution of the different tissue types, but also the radiation characteristics of the typical EM source. Numerical results are given to illustrate the accuracy of the developed procedure. Special emphasis is placed on characterizing and analyzing the EM power deposition patterns obtained using the annular phased array system recently developed by BSD Medical Corporation for hyperthermia treatments.
