FIELD: medicine.
SUBSTANCE: invention relates to a method of automatic segmentation of brain structures. The method contains stages, at which: the brain structure, symmetric with respect to the median saggital plane in the healthy brain, is selected as an anatomical structure of interest; a deformable model of the anatomical structure of interest is selected, with the deformable model being formed from a multitude of polygons; the deformable model is presented on a display; a characteristic point of the anatomical structure of interest is identified; the deformable model is adapted by moving each of the polygons towards respective characteristic points; deformations in the segmentation of the anatomical structure of interest are identified by the identification of the median saggital plane of the said brain and determination for the anatomical structure of interest of deviations in mean values of apexes between left and right hemispheres of the said brain with respect to the median saggital plane of the said brain.
EFFECT: increase of accuracy and reliability of the identification of structural atrophy after a traumatic brain injury.
