The present paper is concerned with the application of microwave thermography to the estimation of temperature profiles inside a human body. The aims of the study are to propose a basic idea of the method of measurement which enables one to estimate the temperature profiles from the measured brightness temperatures, and to design a new radiometer that is suitable for the specific measurement of the brightness. To this end, we reviewed the dielectric properties of biological media. By adopting those properties, a mathematical model of a human tissue was made in order to take a general view of radiation from the body. Based on the results of those theoretical investigations we designed a Dicke-switched superheterodyne multifrequency radiometer equiped with five radiometric frequencies, 1.0, 1.7, 2.8, 4.6 and 10 GHz. The numerical inversion techniques required to estimate the temperature profiles from the measured brightness temperatures were also discussed. The new method of measurement is expected to have a good potential for detecting and localizing subcutaneous thermal abnormalities.
