Abstract.

The “Analyzer of human tissue pathologies “is developed to increase the diagnostic capabilities of standard methods of investigation of organ and tissue damage. Improvement of diagnostic capabilities are achieved by introducing new criterions of quantitative valuation and formalization of diagnostic features, such as structure and tissue of density. The pathology analyzer is a modular system, each module of which is aimed at solving a specific task of image improvement, its evaluation according to new criteria and obtaining additional diagnostic information. The article discusses the developed modules, in particular, the differential diagnostic decision support system, which allows to solve the following tasks: a) assessment the borders of pathologic area. – for example – automatic determination of boundaries of human brain glioma (Combined method of processing CT and MRI images); b) studying the structure of tumors and other pathological changes by creating new approaches in medical images analysis; c) Analysis of MRI images using values normalized by the Hounsfield scale. Mathematical models for each subsystem are developed. Relevance assessment and approbation of the research results is performed with medical experts of different profile: radiologists, pulmonologists, neurosurgeons.
