This work is devoted to the issues of microminiaturization of multichannel multi-frequency medical radiothermographs, which was carried out in several stages. The creation of complex technical systems requires a transition from the design and manufacture of individual parts of the system to the integrated design of the entire system. A system created from optimal parts is not optimal in general, therefore, this paper describes a step-by-step transition from a radiothermograph based on a conventional element base to a constructive design using a microwave MIC, which will lead to an expansion of its functionality and a significant reduction in size. The issues of increasing the noise immunity of the radiothermograph due to the use of optimal antenna-applicator designs are considered. The results of theoretical and experimental studies of the parameters of the microwave MIC for a radiothermograph are presented. The structural schemes of a multichannel multi-frequency radiothermograph are proposed and the ways of creating its design based on MIC-technologies are determined. The integrated design of the radiothermograph will allow achieving an optimal combination of cost and quality. This article discusses the use of affordable and inexpensive devices for the early diagnosis of a large number of diseases, as well as their use in personalized medicine.
