Abstract:

Some studies have shown that pathological processes inside the human body are usually accompanied by a change in the natural thermal field. In order to correctly detect diseases, it is necessary to know the distribution of the thermal field in the human body and on its surface, as well as to know the reactions of the thermal field to physiological tests. As a rule, a person's outdoor temperature is measured with medical thermometers, thermal imagers, or pyrometers. It is impossible to measure the temperature inside the body by such methods, and the introduction of a thermal sensor under the skin leads to a violation of the natural thermal field. Therefore, the task of improving non-invasive methods of measuring internal temperatures in the human body for the purpose of early diagnosis and monitoring of pathological neoplasms is urgent.

There are full-scale experiments on the equivalent of the human body and directly on the human body in order to obtain data for 3D interpolation and visualization on a personal computer monitor screen of the structure of the internal thermal field inside the human body using a five-channel dual-frequency radiothermograph designed to operate in the wavelength ranges of 40 cm and 20 cm.

A five-channel two-frequency radiothermograph has been developed that allows 3D visualization of pathological changes in human internal tissues. Experiments were carried out on the equivalent of the human body and directly on the human body in order to obtain data for 3D interpolation and visualization on a screen of a personal computer of the structure of the internal thermal field inside the human body. It was made with the help of the developed five-channel dual-frequency radiothermograph.

There is possible to use the obtained results for further improvement of the methods of multi-channel multi-frequency radiothermographs in medical practice for more accurate localization of pathological neoplasms inside the human body.
