Предложенные подходы обеспечивают одновременную минимизацию невязки искомого решения и тотальной вариации реконструируемого трехмерного изображения. При этом число необходимых исходных данных (конических рентгеновских проекций), а значит, и лучевая нагрузка на пациента при сохранении необходимого контраста и пространственного разрешения трехмерного изображения могут быть уменьшены в несколько раз. Предложенный эвристический итерационный алгоритм может быть использован как альтернатива известному трехмерному алгоритму Фельдкампа.</p></abstract><trans-abstract xml:lang="en"><p>The principles of fast parallel iterative algorithms based on the use of graphics accelerators and OpenGL library are considered in the paper. The proposed approach provides simultaneous minimization of the residuals of the desired solution and total variation of the reconstructed three- dimensional image. The number of necessary input data, i. e. conical X-ray projections, can be reduced several times. It means in a corresponding number of times the possibility to reduce radiation exposure to the patient. At the same time maintain the necessary contrast and spatial resolution of threedimensional image of the patient. Heuristic iterative algorithm can be used as an alternative to the well-known three-dimensional Feldkamp algorithm.</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">Zolotarev, S.A. 3D Iterative Conical and Spiral Tomography, Laminography, Tomographic Mammography and Tomosynthesis using OpenGL / S.A.
