Differential diagnostics of the presence of damage by the method of digital polarization mapping of microsocopy images of hystological sections of human organs

The article presents the results of experimental testing of methods of azimuthal-invariant polarization mapping of microscopic images of samples of histological sections of the myocardium and lung tissue; time monitoring of changes in the magnitude of statistical moments of the 1-4th orders, characterizing the distributions of the azimuth and ellipticity of polarization of microscopic images of myocardial and lung tissue samples with different age of damage; determination of the diagnostic efficiency (time interval and accuracy) of establishing the age of damage to human internal organs by digital histological methods of mapping azimuth maps and polarization ellipticity of microscopic images. Aim of the work. Development of a digital histology technique for samples of human internal organs. Materials and methods. The object of the study was the histology of samples of human internal organs (myocardium, lung tissue) with different duration of damage from 1 hour to 120 hours. For control, we used BT samples from those who died from coronary artery disease with different duration of damage from 1 hour to 120 hours. The studies were carried out using the method of digital polarization mapping of microscopic images of histological sections of biological tissues of human internal organs. Results. Revealed the following ranges ramp variation quantity statistics polarizing digital histology and accuracy of the limitation of damage: a. Arts azimuth polarization microscopic image of a magnification ×40 (asymmetry – 12 hours, kurtosis – 12 hours, accuracy – 55-60 min), maps of ellipticity of polarization of microscopic images with a magnification of ×40 (asymmetry – 12 hours, kurtosis – 12 hours, accuracy – 65-75 min). Conclusions. Scenarios of changes in the statistical structure of maps of azimuth and ellipticity of polarization of microscopic images of histological sections of human internal organs have been determined - with an increase in the duration of damage, the value of the mean and variance decreases, the asymmetry and kurtosis increase.
