The theoretical background of an azimuthally stable method for Jones-matrix mapping histological sections of biopsy taken from myocardium tissue on the basis of spatial frequency selection of mechanisms responsible for linear and circular birefringence is presented. The diagnostic application of a new correlation parametercomplex degree of mutual anisotropyhas been analytically substantiated. The method for measuring coordinate distributions of complex degree of mutual anisotropy with further

The interrelations of these distributions with parameters of linear and circular birefringence in myocardium tissue histological sections have been found. The comparative results of measuring the coordinate distributions inherent to complex degree of mutual anisotropy related with fibrillar networks of myosin fibrils typical for myocardium tissue in different necrotic states, when death is caused by coronary heart disease and acute coronary insufficiency, have been presented. The values and ranges of changes in the statistical (moments of the 1 st to 4 th order) parameters describing the complex degree of mutual anisotropy coordinate distributions have been studied. The objective criteria for differentiation of causes leading to death have been determined.
