Polarization image processing in the destruction diagnostics of chordae tendinea of atrio-ventricular heart valves

摘要

The aim of this research is to clarify the anizotropic structure and polarization properties of the chordae tendinea of the atrio-ventricular heart valves of the foetus.The researches of images of sections of chordae tendinea of the human heart using the method of laser polarimetry have been carried out to systematically analyze the topography of anisotropic properties of collagen fibers, elastic fibers and contractile cardiomyocytes through the obtained intensity distributions at different polarization orientations of Stokes vector parameters, polarization maps, as well as elements of the Mueller matrixes and their respective statistical moments from the 1st to the 4th order. It was shown that the character of manifestations of anisotropic properties manifested itself in different topographical architectures of these types of fibers with a different level of birefringence, which were visualized in different polarization states of the probing and analyzing beams, which was also described by other scientists.
