Одной из наиболее информативных методик рентгенографии является микрофокусная рентгенография. В ряде случаев микрофокусные рентгеновские изображения не могут быть достоверно проанализированы из-за особенностей способа съемки. Так, основными недостатками микрофокусных рентгеновских изображений чаще всего являются неравномерный фон, искаженные яркостные характеристики и наличие шумов. Предлагаемый метод повышения контраста мелких деталей изображения основан на идее сочетания высокочастотной фильтрации и морфологической обработки изображений. Метод состоит из следующих шагов: подавление шумов на изображении, высокочастотная фильтрация, морфологическая обработка изображения, получение результирующего изображения. В результате применения метода усиливается яркость контуров на изображении. На полученном изображении все объекты будут иметь двойные контуры. Метод был апробирован при обработке 50 рентгенограмм органов грудной клетки пациентов с разнообразной патологией. Рентгенограммы были выполнены в городской Мариинской больнице Санкт-Петербурга на цифровых стационарных и передвижных рентгеновских аппаратах. На большей части рентгенограмм удалось улучшить контраст снимков, выделить границы объектов. Также метод был применен в микрофокусной рентгеновской томографии для улучшения информативности проекционных данных и улучшения восстановления 3D-образа объекта исследования. Как для первого, так и для второго случаев метод показал удовлетворительные результаты. Разработанный метод позволяет существенно повысить информативность микрофокусных рентгеновских снимков. Полученные практические результаты позволяют рассчитывать на широкие перспективы применения метода, особенно в микрофокусной рентгенографии.</p></abstract><trans-abstract xml:lang="en"><p>A method for processing microfocus X-ray images is described. It is based on high-frequency filtration and morphological image processing, which increases the contrast of the X-ray details. One of the most informative X-ray techniques is microfocus X-ray. In some cases, microfocus X-ray images cannot be reliably analyzed due to the peculiarities of the shooting method. So, the main disadvantages of microfocus X-ray images are most often an uneven background, distorted brightness characteristics and the presence of noise. The proposed method for enhancing the contrast of fine image details is based on the idea of combining high-frequency filtering and morphological image processing. The method consists of the following steps: noise suppression in the image, high-frequency filtering, morphological image processing, obtaining the resulting image. As a result of applying the method, the brightness of the contours in the image is enhanced. In the resulting image, all objects will have double outlines. The method was tested in the processing of 50 chest radiographs of patients with various pathologies. Radiographs were performed at the Mariinsky Hospital of St. Petersburg using digital stationary and mobile X-ray machines. In most of the radiographs, it was possible to improve the images contrast, to highlight the objects boundaries. Besides, the method was applied in microfocus X-ray tomography to improve the information content of projection data and improve the reconstruction of the 3D image of the research object. In both the first and second cases, the method showed satisfactory results. The developed method makes it possible to significantly increase the information content of microfocus X-ray images. The obtained practical results make it possible to count on broad prospects for the method application, especially in microfocus X-ray.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микрофокусная рентгенография</kwd><kwd>цифровая обработка изображений</kwd><kwd>фильтрация изображений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microfocus X-ray</kwd><kwd>digital image processing</kwd><kwd>image filtering</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">Arkhipov M.V., Priyatkin N.S., Gusakova L.P., et al.
