Three-dimensional computer simulation in deep regional hyperthermia using the finite-difference time-domain method

Abstract

The finite-difference-time-domain method is used for detailed three-dimensional simulation of the specific-absorption-rate distribution for various prototype applications used in deep regional hyperthermia. The ability to simulate the patterns from the near field of the applicators is demonstrated by comparison with measured data. The method is also used to simulate treatments with commercially available equipment using a detailed model of a cancer patient constructed from computerized axial tomography scans. The model has 1-cm resolution and consists of 34751 cells. The method is further used to anticipate results of treatments with prototype applicators.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
