An increase in the temperature of internal tissues is usually associated with malignant growth, with inflammatory processes, atypical changes, increased proliferation and increased blood flow. A decrease in core temperature is usually associated with a decrease in blood flow. It should also be noted that thermal changes occur at the earliest stage of malignant growth – at the stage of pronounced proliferation and atypical hyperplasia, when there is no malignant tumor yet, but there is a very high risk of malignancy. This opens up the possibility of using the radiometric method for preventive examinations. Microwave radiometer allows non-invasive detection of thermal anomalies at a depth of several centimeters.

The purpose of the work is to acquaint the reader with modern microwave radiometers that are used in medical practice and to formulate the requirements for modern microwave radiometers.

A description of the RTM-01-RES microwave radiometer, which was used for research and clinical trials in various fields of medicine in many countries of the world, is presented. The features of the construction of a microwave radiometer, which made it possible to ensure high measurement accuracy and stability of readings, are described. The technical requirements for microwave radiometers designed to detect thermal anomalies in the patient's internal tissues are discussed.

Numerous studies conducted over the past 20 years have demonstrated the significant potential of microwave radiometry in various fields of medicine. Microwave radiometry is a universal dose-free means of monitoring the functional state of the body.

The research was carried out with the financial support of the Russian science Foundation in the framework of agreement No. 19-19-00349-P in the theme: «A method and a multichannel multifrequency microwave radiometer on the basis of monolithic integrated circuits for finding the 3D distribution and dynamics of brightness temperature in the depths of the human body».
