В основу предложенного подхода положена интеграция трёх взаимодополняющих технологий: многоуровневой свёрточной обработки, остаточных соединений и архитектурных принципов U-Net. Такой подход обеспечивает эффективную обработку объёмных медицинских данных. Построена оригинальная нейросетевая система сегментации полученных методом компьютерной томографии изображений почек и обнаружения опухолей почек. Для валидации построенной системы использовали набор данных, который отвечал следующим критериям: достаточный объём выборки (не менее 300 случаев); экспертная разметка изображений; верифицированные диагнозы; разнообразие клинических случаев; открытый доступ для исследовательских целей. Указанным критериям наиболее полно соответствует набор данных KiTS19 (Kidney Tumor Segmentation 2019), предоставленный Клиникой Университета Миннесоты через платформу Grand Challenge. Набор данных включает 300 размеченных трёхмерных изображений почек с верифицированными диагнозами. Этапы эксперимента: предварительная обработка набора данных, включая нормализацию и аугментацию; обучение разработанной системы на 210 случаях; валидация на независимой выборке из 90 случаев. Результаты эксперимента демонстрируют высокую диагностическую эффективность разработанной системы: точность автоматической сегментации анатомических структур почек составила 96 % (по коэффициенту Дайса); точность обнаружения и сегментации опухолевых образований достигла 91 % (по коэффициенту Дайса). Полученные результаты можно применять в следующих областях клинической практики: предоперационное планирование и навигация при органосохраняющих операциях; автоматизированный скрининг исследований с помощью компьютерной томографии для раннего выявления новообразований почек; количественная оценка динамики роста опухолей при мониторинге течения заболевания; поддержка принятия клинических решений в онкоурологии.</p></abstract><trans-abstract xml:lang="en"><p>In order to improve the accuracy of cancer diagnosis, a new convolutional neural network architecture is presented, which provides automatic segmentation and detection of kidney tumors on three-dimensional images obtained by computed tomography. The proposed approach is based on the integration of three complementary technologies: multilevel convolutional processing, residual connections and U-Net architectural principles. This approach ensures efficient processing of voluminous medical data. An original neural network system for segmentation of kidney images obtained by computed tomography and detection of kidney tumors has been built. To validate the system, a comprehensive experiment was conducted using the publicly available KiTS19 dataset (Kidney Tumor Segmentation 2019) provided by the University of Minnesota Clinic through the Grand Challenge platform. The dataset includes 300 labeled images of kidneys obtained by computed tomography, with confirmed diagnoses. The experiment consisted of the following stages: dataset preprocessing, including normalization and augmentation; system training for 210 cases; validation on an independent sample of 90 cases. The results of the experiment demonstrate the high diagnostic efficiency of the system: the accuracy of automatic segmentation of anatomical structures of the kidneys was 96 % (according to the Dice coefficient); the accuracy of detection and segmentation of tumor formations has reached 91 % (according to the Dice coefficient). The results obtained can be applied in the following areas of clinical practice: preoperative planning and navigation during organ – preserving operations; automated screening of studies using computed tomography for early detection of kidney tumors; quantitative assessment of the dynamics of tumor growth in monitoring the course of the disease; support for clinical decision-making in oncourology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>искусственный интеллект</kwd><kwd>глубокое обучение</kwd><kwd>свёрточные нейронные сети</kwd><kwd>трёхмерная сегментация изображений</kwd><kwd>остаточные сети</kwd><kwd>архитектура U-Net</kwd><kwd>обнаружение опухолей почек</kwd></kwd-group><kwd-group xml:lang="en"><kwd>artificial intelligence</kwd><kwd>deep learning</kwd><kwd>convolutional neural networks</kwd><kwd>three-dimensional image segmentation</kwd><kwd>residual networks</kwd><kwd>U-Net architecture</kwd><kwd>kidney tumor detection</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">Nikitaev V.
