METHOD OF NON-INVASIVE REMOTE TEMPERATURE CONTROL OF DEEPLY LOCATED ORGANS AND TISSUES Russian patent published in 2018 - IPC A61N1/06 A61B5/01 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to diagnostics, and concerns non-invasive remote high-frequency measurement of the temperature of the heating region during high-frequency hyperthermia of deep-lying neoplasms. Method comprises use of part of equipment included in the installation for local or regional hyperthermia. In this case, the high-frequency radiation passing from the radiating dipole antenna passing through the organ or tissue is sent to the high-frequency circulator of the receiving dipole antenna, which is connected to a high-frequency power measurement system. System conversion unit provides an analog signal, i. e. amplitude of the transmitted high-frequency power. Latter is converted into a digital signal and processed by a Fourier analysis program, with the help of which the value of the amplitude of the transmitted high-frequency power is determined. Compare it with “reference” value determined at the initial temperature of 37 °C. By difference in power amplitudes, the temperature in the heating zone is calculated from tabular data or a calibration graph, compiled taking into account the fact that as the difference in temperature increases, the difference between the amplitudes of the current and the “reference” transmitted signals increases according to a law close to linear. Method, being non-invasive, allows to control the temperature in the heating region with an accuracy of at least 0.3 degrees, which is comparable or higher, than for currently used methods, except for fiber-optic ones, with a significant cost reduction in comparison with temperature control with the help of a magnetic resonance tomograph.

EFFECT: method, being non-invasive, allows to control the temperature in the heating region comparable to or higher than for currently used methods, except for fiber-optic, at a significant cost reduction in comparison with temperature control with the help of a magnetic resonance tomograph.
