Differential diagnosis of the prescription of the formation of hemorrhages of traumatic genesis, cerebral infarction, ischemic and hemorrhagic genesis by the method of differential Mueller-matrix mapping of amplitude anisotropy - temporal dynamics of changes in the statistical structure of ALD maps of histological brain sections.
The article presents the results of determining the possibilities of the polarization-singular approach to improve the efficiency of Mueller-matrix polarimetry in the differential diagnosis of polycrystalline structure of optically transparent polycarbonate layers. The relationship between the characteristic values of the elements of the Mueller matrix and polarization-singular L - states of microscopic images of polycrystalline structure of optically transparent polycarbonate layers was determined. A technique for the experimental determination of the distributions of the characteristic values of Mueller-matrix images has been developed and tested. Statistical criteria for express differential diagnosis of polycrystalline structure of optically transparent polycarbonate layers with different mechanical stresses were determined.
This paper provides a model description of the structure of a polycrystalline film of human blood plasma, considered in the form of two components - isotropic and anisotropic or crystalline. The main mechanisms of the processes by which a layer of human blood plasma converts laser radiation parameters linear birefringence of albumin and globulin crystals are considered. The method of Stokes - polarimetric mapping of polycrystalline networks of layers of human blood plasma is given. Experimental examples of the implementation of polarization mapping methods for microscopic images of blood plasma films of patients with various liver pathologies - non-alcoholic fatty disease and chronic hepatitis are presented. The basic operational characteristics (sensitivity, specificity and accuracy) of the strength of the Stokes - polarimetric mapping method are established.
The presented report contains the following materials and results: 1. The structural-logical scheme and design of studies using polarization-phase tomography methods of linear and circular birefringence and dichroism of the polycrystalline structure of histological sections of the brain. 2. Differential diagnosis of the formation of hemorrhages of traumatic origin, ischemic cerebral infarction and hemorrhagic genesis by differential Mueller-matrix mapping of phase anisotropy: • maps of circular birefringence (PCB) of brain histological sections and operational characteristics of the method of their statistical analysis; • maps of linear birefringence (PLB) of histological sections of the brain and operational characteristics of the method of their statistical analysis.
Determination of praline concentration in samples of natural waters, based on the measurement value angle of the plane of polarization of radiation of a certain wavelength λ, which has been studied by the liquid thickness l = 5 sm was developed. Three wavelength λ = 400, 450, 500 nm were used. A series of reference samples was produced: aqueous solutions of L and D forms proline of a known concentration within c = (0.001 – 0,1) %. Based on these studies, for each λ gauge dependent quantities of angle α = f (c) was built. Using them and conducting measurements of angles α for the real natural environments, the possibility of determination of the concentration of proline in them was actualized. It was determined that in waters within the city of Chernivtsy and its surroundings occured proline of two forms: L and D, the concentration of which is within c = (0,005 - 0,094)%
This research contains materials of experimental studies of the coordinate structure of the distribution of polarization ellipticity of spectral ("red"λ1 = 0,632μm and "blue"λ1 = 0,414μm) laser images of punctate samples of healthy (group I), preoperative (group II) patients and postoperative (group III) cancer patients. Two-dimensional distributions of elliptic polarization values of the "red" and "blue" laser images of punctate oncological patients of groups I, II and III are presented and analyzed. Samples of stationary values of the polarization ellipticity of laser images of punctate samples of three groups of oncological patients were studied and the patterns of their coordinate and spatial-frequency construction were established. On this basis, polarization criteria for the differentiation of laser images of patients of groups I, II and III are established. The ranges of changes in the statistical moments of the first and fourth orders of the coordinate distribution of
polarization ellipticity (“red” λ1= 0,632μm and “blue” λ1=0,414μm) laser images were studied, and statistical criteria for the differentiation of laser images of patients A, B and C groups were established. Some legal aspects of labor adaptation revealed by the proposed diagnostic methods in labor and social collectives are considered.
This research contains the results: 1. of the method of Stokes-correlometric mapping, the physical processes of changes in optical anisotropy (distribution of optical axis directions and phase modulation) of biological structured (kidney) and parenchymal (liver) tissues of rat internal organs, which are caused by systemic pathology (diabetes), were identified and analyzed as part of a statistical analysis. 2. of the most sensitive parameters (statistical moments of the 1st – 4th orders of magnitude, the correlation moment of the 4th order) to changes in the distribution structure of the magnitude and phase of the SCS of the 3rd and 4th parameters of the “two-point” parameter of the Stokes polarization heterogeneous microscopic images of histological sections of healthy and diabetic rat kidney and liver tissues. 3. of social and legal aspects of implementation of methods for early diagnosis of systemic diseases in public society.
