Abstract :
Summary form only given. The polarization tomography features of optically anisotropic architectonic nets of different morphological structure biotissues (BT) have been investigated. The phase tomography (PT) features of skin derma, muscular and bone BT have been experimentally investigated. The interrelation between the PT structure and BT physiological state has been determined. The early diagnostics criteria of the degenerative-dystrophic appearance and pathological changes of the structure of BT optically anisotropic architectonics have been determined: (i) Optical anisotropy of physiologically normal myometry is not practically apparent- the PTs represent a quasi-homogeneous field with several fluctuations Δn(X,Y) ≈ 10-5. This points to a rather amorphous optical structure of BT, i.e., to "lack of development" of myometry collagen net. (ii) The phase component topology of the diffusely changed myometry architectonics is formed by the areas with inhomogeneous distribution of birefringence Δn(X,Y), the values of which vary from 1.2 × 10-4 to 1.1 × 10-3 respectively. (iii) The tumor-forming processes are accompanied by the formation of "anisotropy zones", within which the birefringence value of architectonics increases by two orders and reaches the level of 2.5 × 10-3.
