DEGREE OF MUTUAL POLARIZATION OF MYOCARDIUM TISSUE LASER IMAGES

Abstract

Purpose. Degree of mutual polarization of laser images ofbiological tissues can be used to diagnose the orientational birefringent structure of their physiologically normal and pathologically changed architectonic nets.Design/approach. The study objects were “optically thin”histological sections of physiologically normal and dystrophicchanged muscle myocardium tissue. For the analysis of polarizationinhomogeneous fields an approach, proposed by Dohariu, in whichthe correlation between the states of polarization (α,β) of the objectfield in different points (r1, r2) with the amplitudes U(r1), U(r2) isconsidered as the degree of mutual polarization V2(r1, r2). Change ofcoordinate distributions of degree of mutual polarization of laserimages of biological tissues of different physiological state are characterized by statistical moments of 1-4 orders.Conclusion. Statistical analysis of coordinate distributionsof degree of mutual polarization of laser images of muscle myocardium tissue showed the effectiveness of diagnostic use forpreclinical diagnosis of degenerative changes in its structure.Most sensitive to changes in orientation of the birefringent fibrilsoptical axes are asymmetry of distribution of the degree of mutual polarization, its values that characterize abnormal tissueimages differ from the values that characterize healthy tissueimages in several times.
