PCT No. PCT/US93/09480 Sec. 371 Date Aug. 14, 1995 Sec. 102(e) Date Aug. 14, 1995 PCT Filed Oct. 4, 1993 PCT Pub. No. WO94/07408 PCT Pub. Date Apr. 14, 1994This 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 mu 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.
