MORPHOMETRIC ANALYSIS OF BRAIN STRUCTURES

Abstract

From the point of view of information saturation of the image, much attention is paid to contrast. This parameter allows you to visually, albeit subjectively, set the boundaries of different areas on the image surface. Modern computer programs allow us to reproduce adequate estimates of tissue contrast. The results of the examination of brain structures (SGM) are presented in mm3 dimensions, which in physical interpretation indicates the presence of estimates of the volume of neural structures of the brain. Such a concept of the final result is created on the basis of representations of a single element of a graphic image - a voxel. For these purposes, mathematical dependencies (models) are implemented that have the property of outlining the contours of an object, or formal mathematical models that have the property of describing the internal structure of an object, taking into account the observed external image or contour. The internal structure of the object is created on the basis of small elements set programmatically in three dimensional space (1 × 1 × 1, mm3). The article presents a systematic approach to the analysis of the data obtained during MRI studies, which allows obtaining visual images. Using the concepts and definitions of geometric modeling, a set of computational procedures for constructing and reproducing an illustrative image of fragments of a biological object in the interactive mode of computer graphics has been created. The possibility of conjugate positioning of informational visual images executed in the basis of different physical principles of image formation, providing the formation of an adequate medical judgment, has been established. The clarity and visibility of the results obtained, reproduced on the model, can significantly improve the efficiency of the analysis of neural structures of the brain.Keywords: Medical diagnostics, MR morphometry, model, visualization of MRI data.
