Вместе с тем расширение парка рентгенологического оборудования, внедрение телемедицины и сервисов поддержки врачебных решений на основе искусственного интеллекта требуют модернизации систем хранения и обработки изображений в уже существующих системах.</p><p>В данной статье представлен обзор современных методов сжатия радиологических изображений, которые обеспечивают более высокий коэффициент сжатия, улучшенное качество изображения и меньшее время кодирова­ния/декодирования по сравнению со стандартами, предусмотренными спецификацией DICOM. Обзор научных публикаций позволяет заключить, что рентгенологические изображения обладают рядом особенностей, учет которых в алгоритмах сжатия позволяет улучшить показатели сжатия изображений. К таким особенностям от­носятся: высокая зашумленность, наличие локально симметричных областей (схожих участков), а также при­сутствие множества последовательных кадров в рамках одного исследования.</p><p>Применение современных подходов к сжатию данных способно повысить отказоустойчивость высоконагруженных медицинских систем и сократить затраты на хранение, передачу и обработку диагностических исследований.</p></abstract><trans-abstract xml:lang="en"><p>The automation of radiology services has significantly improved access to radiological imaging for accurate diagnosis of diseases and injuries. However, the expansion of radiological equipment, the adoption of telemedicine, and the integration of AI-powered clinical decision support systems necessitate upgrades to existing medical image storage and processing solutions.</p><p>This article reviews modern compression methods for radiological images, which offer higher compression ratios, im­proved image quality, and faster encoding/decoding times compared to the standards defined by the DICOM specification. It is established that radiological images possess unique characteristics—such as high noise levels, locally symmetric regions (similar patches), and the presence of multiple sequential frames in a single study—which, when accounted for in compression algorithms, can enhance compression efficiency.</p><p>Implementing advanced data compression approaches can increase the fault tolerance of high-load medical systems and reduce costs associated with the storage, transmission, and processing of diagnostic studies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сжатие изображений</kwd><kwd>медицинские данные</kwd><kwd>обзор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>image compression</kwd><kwd>medical data</kwd><kwd>review</kwd><kwd>state of art</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания МГУ им.
