Оценить возможность использовать программу цифровой обработки изображений для маммографии «СиГрид» (виртуальный растр) вместо традиционного подвижного отсеивающего растра.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. На базе маммографа Маммо-4МТ-Плюс (АО «МТЛ», Москва) проведено сравнение виртуального растра «СиГрид» (АО «МТЛ», Москва) со штатным подвижным растром. На лабораторном этапе использовались фантомы CDMAM и CIRS 010D. На этапе работы в клинике сравнивались дозы в выборках из 1063 исследований с физическим растром и 1132 исследований с виртуальным растром. Для сравнения качества изображений по 200 случайным исследованиям из каждой выборки были независимо вслепую оценены тремя рентгенологами.</p></sec><sec><title>Результаты</title><p>Результаты. При одинаковых дозах метрики качества, посчитанные на фантомах CDMAM и CIRS 010D с виртуальным растром, были не ниже, чем с физическим растром. Рентгенологи в среднем значимо выше оценили качество снимков с виртуальным растром, чем с физическим. Средняя доза в выборке с виртуальным растром оказалась на 22 % ниже, чем в выборке с физическим растром.</p></sec><sec><title>Заключение</title><p>Заключение. Виртуальный растр «СиГрид» может применяться вместо подвижного физического растра для маммографии. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective.

On the basis of the mammograph Mammo-4MT-Plus (JSC «MTL», Moscow), the «SyGrid» software grid was compared with a standard movable grid. At the laboratory stage, CDMAM and CIRS 010D phantoms were used. At the clinical stage, doses were compared in samples of 1063 studies with a physical grid and 1132 studies with a software grid. To compare the image quality, 200 random studies from each sample were independently blindly evaluated by three radiologists.</p></sec><sec><title>Results</title><p>Results. At equal doses, the quality metrics calculated with CDMAM and CIRS 010D phantoms with a software grid were no lower than with a physical grid. Radiologists, on average, rated the quality of images with a software grid significantly higher than with a physical one. The average dose in the sample with a software grid was 22 % lower than in the sample with a physical grid.</p></sec><sec><title>Conclusion</title><p>Conclusion. The «SyGrid» software grid can be used instead of a movable physical grid for mammography.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цифровая маммография</kwd><kwd>рассеянное излучение</kwd><kwd>лучевая нагрузка</kwd><kwd>качество изображения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Digital Mammography</kwd><kwd>Scatter Radiation</kwd><kwd>Radiation Exposure</kwd><kwd>Image Quality</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">Виноградов И.
