Алгебраический метод реконструкции с одновременными итерациями SART рассматривается в данной работе как один из перспективных итерационных методов, пригодных для решения томографических задач. Для ускорения быстродействия используется графический процессор. Метод минимизации тотальной вариации (TV) используется как априорная поддержка для регуляризации итерационного процесса и преодоления неполноты информации.</p></abstract><trans-abstract xml:lang="en"><p>Computed tomography is still being intensively studied and widely used to solve a number of industrial and medical applications. The algebraic reconstruction method with simultaneous iterations SART considered in this work as one of the most promising of iterative methods, suitable for the tomographic problems. Graphics processor is used to accelerate the speed of the reconstruction. The method of minimizing the total variation (TV) is used as a priori support for the regularization of the iterative process and to overcome the incompleteness of the information.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Niklason L.
