Modelling of electromagnetic interaction and local temperature increase in human tissues

Hyperthermia is defined as the heating of cancer tissues by means of a microwave antenna system. To that end the temperature of the cancer tissue depending on its character exposed to electromagnetic field to rise the temperature between 41degC and 44degC. An important step in this application is while you increase the temperature in cancer tissue the healthy tissues must be not damaged. The aim of this paper is the modeling of some part of human body with containing cancer tissues exposing it to electromagnetic field under a system, calculating the SAR values and observing the temperature distribution. As a first step we designed a three-dimensional neck-head model and to apply hyperthermia method we used four dipole circular array antennas. The designed model is simulated by means of SEMCAD program using the FDTD method and the results are presented. The aim of this work is to make a begin to be able to apply the hyperthermia patient specific and cancer type specific to elevate the temperature locally on cancer tissues.
