Учитывая рост интереса исследователей и клинических специалистов к алгоритмам обработки медицинских данных, существенно возросли перспективы прикладного применения подобных подходов – прежде всего использования глубоких нейронных сетей в задачах детекции патологических участков. Однако использование таких методик сопряжено с низким уровнем точности локализации, недостаточным для трансляции наработок в область ассистирующих систем для принятия врачебных решений.</p></sec><sec><title>Цель</title><p>Цель. Настоящее исследование направлено на оценку скорости и точности работы современной архитектуры сверточной нейронной сети RFCN ResNet-101 V2 для перспектив автоматизированной обработки клинических данных коронарографий.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Основой для обучения выбранной архитектуры нейросети стали клинические графические данные коронарографии 50 пациентов, у которых было выявлено наличие одноочаговых поражений (стенозов) более 75%.

Considering the growing interest of researchers and clinical specialists in algorithms for processing medical data, the prospects for the applied application of such approaches have significantly increased, primarily, involving the use of deep neural networks in the tasks of detecting pathological areas. However, the use of such approaches is associated with a low level of localization accuracy, insufficient to translate the developments into the field of assistive systems for making medical decisions.</p></sec><sec><title>Aim</title><p>Aim.

The basis for the chosen neural network architecture training was the clinical graphic data of 50 patients subjected to routine coronary angiography, which is characterized by the presence of single-focal lesions (stenoses) in more than 75% of all cases.

The results obtained determine the further direction of development of the presented approach, which should be reducing the time of analysis of each frame of coronary angiography due to image preprocessing methods.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нейронная сеть</kwd><kwd>коронарография</kwd><kwd>mAP</kwd><kwd>локализация</kwd><kwd>стеноз коронарной артерии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neural network</kwd><kwd>coronary angiography</kwd><kwd>F1-score</kwd><kwd>localization</kwd><kwd>stenosis of the coronary artery</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Сердечно-Сосудистая Хирургия — 2018.
