Background: Monitoring of temperature changes and accurately determining the moment of electrode removal during open heart operations is not well recognized.
Objective: We investigated the temperature fields distribution in the biological tissues affected by electrosurgery upon use of an infrared thermograph.
Methods: The dynamics of temperature distribution in the tissue was registered by the thermal imaging camera FLIR i7.
Background: In this paper a method is proposed to evaluate the heart's coronary vessels' status based on the elimination of large coronary branches from IR-thermal image. This method makes it possible to determine nutrient cardiac blood circulation by calculation of the rate of heat spreading in small coronary vessels in the myocardium at hypothermia and hyperthermia under the conditions of artificial blood circulation.
Objective: The objective of the paper includes a theoretical substantiation of the proposed method for evaluation of the heart's coronary vessels' status and an experimental investigation of the efficiency of the method.
In the paper, an opportunity for the development of multichannel transcutaneous raster matrixes for sensors of oxygen on the basis of an electrochemical cell sensor is described. An analysis of the influence of heat sources on the distribution of the temperature pattern of a raster matrix for sensors of oxygen had been carried out, and their optimum configuration had been found. The application of such matrixes will enable one to obtain information about the distribution of the partial pressure of oxygen from the skin cover of the object of research in dynamics, to assess its functional health pattern in a more comprehensive way and to control the effect of possible remedial actions.
