Работа выполнена с использованием фантома ACR CT PHANTOM для компьютерного томографа Philips Ingenuity 128. Оценка качества изображения  осуществлялась по точности определения единиц Хаунсфилда, шума изображения, отношения контраста к шуму и пространственного разрешения.</p><p>Результаты исследования показали, отсутствие достоверных различий между различными низкодозовыми протоколами. При этом наблюдалась слабая корреляция между результатами физико-технических параметров изображения и экспертной оценки качества изображения, что не позволяет принимать решение о внедрении низкодозовых протоколов в практику, основываясь только на оценке физико-технических параметров.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the current study was to assess the physical and technical image quality parameters of the CT images obtained on low-dose chest protocols.</p><p>Materials and methods. The study was performed using the ACR CT PHANTOM on the Philips Ingenuity 128 CT unit. The following parameters were selected for the assessment of image quality: Hounsfield unit accuracy, image noise, contrast to noise ratio and spatial resolution.</p><p>The results of the study indicate the lack of significant differences between the selected low-dose protocols.  Additionally, the correlation between the results of the assessment of physical and technical parameters of CT  images and expert image quality evaluation was weak. That does not allow implementing the low-dose protocols  into clinical practice based solely on the assessment of the physical and technical parameters. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>оптимизация</kwd><kwd>оценка качества</kwd><kwd>низкодозовое сканирование</kwd><kwd>итеративные реконструкции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computed tomography</kwd><kwd>optimization</kwd><kwd>quality assessment</kwd><kwd>low-dose scanning</kwd><kwd>iterative reconstructions</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">Онищенко Г.Г., Попова А.Ю., Романович И.К., Водоватов А.В., Башкетова Н.С., Историк О.А., Чипига Л.А., Шацкий И.Г., Репин Л.В., Библин А.М.
