Techniques for statistical data analysis are widely used in the construction of systems of support of making decision in various analytical fields of human activity, including in the field of medicine. Therefore there is urgent need to establish a system of pre-processing and analysis of primary care data with its subsequent performance in the form of quantitative characteristics that simplify the decision process by a clinician in differential diagnosis of diseases. The task of differential diagnosis of ENT diseases can be solved by constructing mathematical models of the studied object, the quantitative characteristics which serve as evaluation criteria and allow to confirm or refute the hypothesis clinician about the state diagnosed pathology. When processing x-ray tomographic image as an object of diagnosis is necessary to face the requirements of the quality process of image processing associated with the lack of information pathologies of the biological objects. The presence of logic controllers with adaptive variable priority required by practice of digital image processing systems for information support of decision making in real time. The authors present an algorithmic hardware and software structure of the mobile diagnostic terminal. This terminal is endowed with the ability of self-learning, i.e. the formation of a database for measurement standards of known classes of pathologies of the maxillary and frontal sinuses, with the subsequent issuance of the thresholds on the monitored inputs logic controller, is able to reconfigure its structure to be able informative management selection of informative data streams depending on the priority. In other words, logic controller with variable input priority information flow in computers, is an adaptive interface for a diagnostic terminal. The article also presents a method of sequence-relator-based logical structures of different algorithms: cyclic group with a decomposition algorithm «daisy-chain», «daisy-ring», which allows to synthesize logic controllers input radiographic visual information in the computer and provide information and hardware communication «computer-logic controller». Logic controller implemented on the principle of «daisy-chain-ring» does not require synchronization because they have no Autonomous subsystem clock, and it is the role of the clocking subsystem PC that sends the reset signal to respective inputs of the controller. The controller «daisy-ring», is a versatile focal power which is 2n!, because it can function as a cyclic priority polling. Presents the implementation of the controller offers the advantage of low hardware cost and enhanced functionality relative to domestic and foreign decisions of the interrupt controllers. The results of the studies presented in this paper were obtained with the financial support of the Ministry of education and science of the Russian Federation in the framework of the state assignment No. 2014/74 «Development of systems for diagnosis of biological and technical objects with the use of algorithms analysis of non-stationary signals». The research was conducted in Southern Federal University.
