Wavelet analysis for polarization inhomogeneous laser images of blood plasma
The possibilities of the local wavelet-analysis of polarization-inhomogeneous laser image of human blood plasma were considered. The set of statistics, correlation and fractal parameters of the distributions of wavelet-coefficients that are characterize different scales of the polarization maps of polycrystalline networks of amino acids of blood plasma were defined. The criteria for the differentiation of the transformation of birefringence optical-anisotropic structures of blood plasma at different scales of their geometric dimensions were determined
Fractal Structure of Optical Anisotropy Mueller-Matrices Images of Biological Layers
The basic crystal optical mechanisms of formation of polarizable singularity images of polycrystalline networks of body fluid films with slight phase fluctuations were determined. Coordinate allocation of L - states is conditioned by the interaction of laser radiation with the substance of optically active proteins; C -states form on account of the phase modulation of orderly acicular protein crystals. On this basis the new Mueller-matrices method of diagnostics and differentiation of the changes of birefringence of body fluid films was developed and nosology differentiation was carried out for the first time. The results of the comparative study of the diagnostic effectiveness of the use of statistic, correlation, and fractal analysis of allocation of the characteristic meanings of the phase Mueller-matrices images in the differentiation of the polycrystalline film structure changes of body fluids were given
The Interconnection between the Coordinate Distribution of Mueller-Matrixes Images Characteristic Values of Biological Liquid Crystals Net and the Pathological Changes of Human Tissues
We have theoretically grounded conceptions of characteristic points observed in coordinate distributions of Mueller matrix
elements for a network of human tissue biological crystals. The interrelation between polarization singularities of laser images
inherent to these biological crystals and characteristic values of above matrix elements is found. We have determined the criteria
for statistical diagnostics of pathological changes in the birefringent structure of biological crystal network by using myometrium
tissue as an example
Wavelet-analysis for Laser Images of Blood Plasma
The possibilities of the local wavelet-analysis of polarization-inhomogeneous laser image of human blood plasma were considered. The set of statistics, correlation and
fractal parameters of the distributions of wavelet-coefficients that are characterize different scales of the polarization maps of polycrystalline networks of amino acids of blood plasma were defined. The criteria for the differentiation of the transformation of birefringence optical-anisotropic structures of blood plasma at different scales of their geometric dimensions were determined
Evolution of Mueller Matrix Images of the Myometrium for the Optical Anisotropy Oncological Changes
The optical model of polycrystalline networks of myometium is suggested. The results of investigating the interrelation between the values correlation (correlation area, asymmetry coefficient and autocorrelation function excess) and fractal (dispersion of logarithmic dependencies of power spectra) parameters are presented. They characterize the distributions of Mueller matrix elements in the points of
laser images of myometrium histological sections. The criteria of differentiation of death coming reasons are
determined
Wavelet analysis for polarization maps of networks formed by liquid biological crystals in blood plasma: statistical and fractal approaches
Considered in this paper are the possibilities of local wavelet analysis for
polarization-inhomogeneous images inherent to blood plasma of healthy and
oncologically ill patients. Determined is the set of statistical, correlation and fractal
parameters for distributions of wavelet coefficients that characterize different scales of
polarization maps inherent to polycrystalline networks of amino-acids in blood plasma.
Established are criteria for differentiation of processes that provide transformation of
birefringent optically-anisotropic structures in blood plasma for various scales of their
geometrical dimensions
Mueller-matrix diagnostics of optical properties inherent to polycrystalline networks of human blood plasma
This work is aimed at studying the possibilities of Mueller-matrix diagnostics
applied to optically anisotropic birefringent polycrystalline networks inherent to amino
acids in human blood plasma. Determined here are interrelations between statistical
moments of the first to fourth orders as well as fractal dimensionalities that characterize
coordinate distributions of blood plasma Mueller-matrix elements and the physiological
state of a human organism
Birefringence images of polycrystalline films of human urine in early diagnostics of kidney pathology
We propose an optical model of the Mueller-matrix description of mechanisms of optical anisotropy of polycrystalline films of urine, namely, optical activity and birefringence. The algorithm of reconstruction of distributions of parameters-optical rotation angles and phase shifts of the indicated anisotropy types-are elaborated upon. The objective criteria of differentiation of urine films taken from healthy donors and albuminuria patients by means of statistical analysis of such distributions are determined. The operational characteristics (sensitivity, specificity, and accuracy) of the Mueller-matrix reconstruction method of the optical anisotropy parameters are defined
Azimuthally invariant laser polarimetry of polycrystalline smears of biological liquids
The model based on Mueller-matrix description of mechanisms providing optical anisotropy typical for polycrystalline smears of liquor (including optical activity, birefringence as well as linear and circular dichroism) has been suggested. Within the statistical analysis of such distributions, the objective criteria of differentiation of smears of liquor taken from dead patient at different moments after his death have been determined. From the viewpoint of probative medicine, the operational characteristics (sensitivity, specificity and accuracy) of the method of Mueller-matrix reconstruction of optical anisotropy parameters have been found and the efficiency of this method in another task – diagnostics of diseases of internal organs of rats – has been demonstrated
Complex degree of coherency inherent to laser images of blood plasma polycrystalline networks
Given in this paper are theoretical basics for correlation-phase analysis of laser
images inherent to human blood plasma. Also presented are comparative results of
measurements aimed at coordinate distributions of the module of complex degree of
coherency (CDC) and complex degree of mutual polarization (CDMP) of laser images
describing blood plasma of a healthy person as well as of a patient with prostate cancer
of the first stage. The authors investigated both values and ranges of changing the
statistical (moments of the first to fourth orders), correlation (coefficients of the GrammCharlie
expansion for autocorrelation functions) and fractal (slopes and dispersion of
extremes for logarithmic dependences of power spectra) parameters for coordinate
distributions CDC and CDMP. Determined are objective criteria for diagnostics of cancer
changes in blood plasma of a patient with cancer
