[Significance of the method of fractal dimension assessment of x-ray images in the differential diagnosis of spherical formations of the lungs].
A posterior processing of tomograms was made in 210 patients with spherical formations of the lungs of various etiological factors. The method based on tomograms delicate texture study according to the system of 7 diagnostic signs by means of the fractal dimension of X-ray pictures of the pathological focuses made the tomography diagnosis more informative in lung spherical formations substrate recognition. The method of fractal estimation allowed to reach a 14.7% rise of the precision, a 12.6% rise of the sensitiveness and a 17.1% rise of the specificity of diagnosis as compared with the routine X-ray research.
