Abstract
Problem formulating. An important task of laser surgery is the development of methods for performing operations, in which the type or state of the tissue being treated is simultaneously controlled. It is known that electrical radiofrequency properties are different for different types of biological tissues, and also significantly depend on temperature and change during degradation.
Goal. Show the possibility of using radiofrequency impedansometry as a method for monitoring the state of tissue under local exposure to laser radiation.
Result. The work shows the high repeatability and sensitivity of radiofrequency impedansometry in the task. It was also demonstrated that the electrical impedance measurement method, together with mathematical modeling, makes it possible to control both the state and temperature of biological tissues.
Practical meaning. This work can serve as a basis for further development of hybrid medical devices that combine the advantages of optical impact on biological tissues with the diagnostic capabilities of bioimpedansometry.
