Device to determine the level of peripheral blood circulation and saturation
(Society of Photo-Optical Instrumentation Engineers, 2016)
The paper evaluated the diagnostic value of laser photoplethysmography when examining patients with chronic lower limb ischemia. A statistical analysis of the research results was made, and diagrams of relationship between ...
Physical-mathematical model of optical radiation interaction with biological tissues
(Society of Photo-Optical Instrumentation Engineers, 2017)
The physical-mathematical model of distribution of optical radiation in biological tissues was developed. It allows determining the change of intensity of optical radiation depending on such parameters as installation angle ...
Application of a modified evolutionary algorithm for the optimization of data acquisitionto improve the accuracy of a video-polarimetric system
(Society of Photo-Optical Instrumentation Engineers, 2015)
The use of the polarimetry techniques for display and study of biological tissues has gained increasing interest in recent years. This interest is related mainly to the non-invasiveness, relatively low cost, and ease of ...
