Abstract :
This paper presents problems related to thermal radiation of human bodies in the microwave range in relation to diagnosis of breast carcinoma. A mathematical model of thermal radiation transmission through tissues is introduced and methods of measurement of temperature and the depth and size of a heat source, by means of multifrequency microwave thermography, are described. Theoretical considerations are supplemented by results of experiments.
