Résumé

One of the current problems at the interface of medicine, tool engineering, mathematical modeling and data mining is a creation of new generation of medical devices and methods of functional diagnostics based on dynamic mapping of physical fields and radiation of human body. One promising approach is the microwave radiometry as a biophysical method of non-invasive survey, which is measuring the internal and surface tissue temperature from the intensity of the thermal radiation in the microwave and infrared ranges. Analysis of domestic and foreign literature on medical microwave radiometry apparatus showed that now many questions of principle technology of highly informative receivers for thermal electromagnetic radiation in relation to medical problems are solved. Both abroad and in our country there is an intensive study of the diagnostic capabilities of radiometry in different wavelength ranges in various fields of applied medicine. However, the development of effective methods of medical diagnosis has an obstacle as the lack of sufficient quantitative and qualitative description of the behavior of temperature fields in various human organs as in the presence of pathological processes, so in their absence. The authors presented review analysis of the works devoted to the description, mathematical modeling and interpretation of data obtained from microwave radiometry, and it is one of the steps to solve this problem.
