The paper presents a developed approach to the hippocampus detection and subsequent calculation of its parameters, as the most informative object of the brain for Alzheimer's disease signs detecting, while analyzing a images series of a magnetic resonance tomograph obtained in a sagittal projection. Algorithms for detecting key frames in the entire series containing the hippocampus and identifying the hippocampus among other brain structures are proposed. The problems of measuring the volume parameters of the hippocampus and calculating its characteristics are considered, which serve as the basis for instrumental objective calculation of the signs characterizing the possible presence of Alzheimer's disease.ΠΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΠ΅ Π²ΡΠΏΠΎΠ»Π½Π΅Π½ΠΎ Π·Π° ΡΡΠ΅Ρ Π³ΡΠ°Π½ΡΠ° Π ΠΎΡΡΠΈΠΉΡΠΊΠΎΠ³ΠΎ Π½Π°ΡΡΠ½ΠΎΠ³ΠΎ ΡΠΎΠ½Π΄Π° (ΠΏΡΠΎΠ΅ΠΊΡ 17-11-01288)
