The diagnostic application of a new correlation parameter - complex degree of mutual anisotropy - has been analytically substantiated. The method for measuring coordinate distributions of complex degree of mutual anisotropy with further spatial filtration of their high- and low-frequency components has been developed. 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.
