Local heat source detection inside of the human body by means of microwave radiothermography

The possibility of non-invasive simultaneous detection of the depth and the temperature of a cancerous tumor inside the human body by means of multifrequency microwave 3D-radiothermograpy is regarding. The models for the description of the reception processes of the own human radio-thermal field are resulted. The possibility of calculating the required parameters by measuring antenna temperatures simultaneously in two different frequency ranges is analyzed. The conditions for solutions finding by bothanalytical and numerical methods are revealed. The possible maximum depth for tumors detection depending on the parameters of radiothermograph and thermal contrast in the source is determined. The necessitate of multi frequency receiving is approving. Analytical solutions for tumor depth and temperature for the current model are presented. © 2020 Russian Academy of Natural Science.
