Dynamic Active Microwave Thermography Applied to Hyperthermia Monitoring

Abstract

The paper presents a numerical simulation of the active tomographic imaging of temperature changes induced in human pelvis and thorax during hyperthermia treatments of cancer. Thermal images would allow monitoring and optimization of treatment, increasing its efficacy and avoiding the heating of healthy tissues. The fields scattered by a numerical reference phantom and the same model locally heated have been calculated at 434 MHz. From this data, differential images have been reconstructed with a first order algorithm showing approximately the heated region
