Разработан алгоритм подавления контрастного усиления в области брюшного отдела аорты на КТ-изображении. Научная новизна подхода заключается в преобразовании размеченных контрастированных изображений в бесконтрастные с помощью разработанной математической модели, позволяющей выделить и подавить составляющую рентгеновского поглощения контрастного вещества. Тестирование алгоритма проведено на открытом наборе данных, состоящем из 4 КТ-исследований брюшного отдела аорты, баланс классов „аневризма:норма“ — 1:1. Результаты демонстрируют сопоставимость значений рентгеновской плотности в области исследования с литературными данными, а также сходство этой области с окружающей мышечной тканью. Экспертная классификация смешанной выборки, содержащей реальные и сгенерированные изображения, продемонстрировала реалистичность последних (точность обнаружения искусственных изображений — 35 %, каппа Флейса — 0,12). Полученные изображения предназначены для обучения и тестирования алгоритмов искусственного интеллекта в сфере оппортунистического скрининга аневризмы аорты.</p></abstract><trans-abstract xml:lang="en"><p>An approach to the automated acquisition of non-contrast computed tomography (CT) images containing abdominal aortic markings derived from contrast-enhanced phase scanning data is presented. An algorithm for suppressing contrast enhancement in the area of the abdominal aorta on a CT image is developed. The scientific novelty of the approach lies in the conversion of marked contrast images into non-contrast images using a developed mathematical model that allows for isolation and suppression of the component of X-ray absorption of the contrast agent. The algorithm was tested on an open data set consisting of 4 CT studies of the abdominal aorta, the balance of “aneurysm: normal” classes was 1:1. The results demonstrate the comparability of the X-ray density values in the study area with literature data, as well as the similarity of this area with the surrounding muscle tissue. Expert classification of a mixed sample containing real and generated images demonstrates the realism of the latter (accuracy of detection of artificial images - 35%, Fleiss kappa - 0.12). The resulting images are intended for training and testing artificial intelligence algorithms in the field of opportunistic screening of aortic aneurysm.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>обработка изображений</kwd><kwd>обучающие наборы данных</kwd><kwd>искусственный интеллект</kwd><kwd>синтетическая бесконтрастная фаза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computed tomography</kwd><kwd>image processing</kwd><kwd>training datasets</kwd><kwd>artificial intelligence</kwd><kwd>synthetic noncontrast phase</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках НИР/НИОКР (№ ЕГИСУ: 123031500002-1) в соответствии с Приказом от 21.12.2022 г. № 1196 „Об утверждении государственных заданий, финансовое обеспечение которых осуществляется за счет средств бюджета города Москвы, государственным бюджетным (автономным) учреждениям, подведомственным Департаменту здравоохранения города Москвы, на 2023 год и плановый период 2024 и 2025 годов“; авторы выражают благодарность сотрудникам НПКЦ ДиТ ДЗМ, врачам-рентгенологам И.
