Method of investigation of microcirculation functional dynamics of physiological liquids in skin and apparatus for its realization

摘要

This method and apparatus characterizes the interconnection between blood content and capillary blood flow and accomplishes a functional diagnosis of microcirculation of physiological liquids in the skin. In this invention there is a sequential recording of the IR radiation emitted by the skin with simultaneous recording of backscattered electromagnetic radiation at visible and near IR wavelengths under conditions of external illumination over the same region with subsequent superimposition of the images obtained thereby. The parameter to be measured is the relationship between the temporal changes in backscattered electromagnetic radiation in at least one of the spectral ranges of 0.3 to 2.0 &mgr;m and changes in intensity of emitted IR radiation. This parameter is represented in the form of spatial- temporal distribution within the boundaries of the image region under investigation.
