Polarization structural property of the images of chordae tendineae of the mitral and tricuspid heart valves of the infants

摘要

The aim of this study is to study the microscopic, submicroscopic structure and polarization properties of the chordae tendineae of the atrio-ventricular valves of the heart of infants. Methods of laser polarimetry provide additional information about the morphological and optico-anisotropic structure of the biological tissues in norm and in pathology, which is aimed at visualization and in order to receive of the informative images of the polarization-inhomogeneous object fields and their statistical analysis, makes it possible to establish the differential signs of the biological tissues state in norm and pathology. The disordered architectonics of cardiomyocytes of various localization was manifested in false tendons of fibro-muscular and muscular types. The topologically localized and phase-inhomogeneous component of the anisotropic formations of cardiomyocytes manifested itself in the values of statistical moments of higher orders of the Stokes vector-parameter S_3. The correlation characteristic of the filtered collagen network indicates an ordered and largescale character of manifestations of hierarchical anisotropy of collagen fibers with a distinct difference in the values of the fourth-order statistical moment (excess) of the values of the ellipticity of the polarization of the image.
