В исследовании использовались 8 инсулиновых шприцев объемом 1 мл, наполненных раствором гидроортофосфата калия, с разными характеристиками плотности. В дальнейшем данные шприцы на равном расстоянии друг от друга были помещены в два фантома: фантом 1-го типа – бокс, заполненный водой, фантом 2-го типа – Chest Phantom N1 “LUNGMAN”. Фантомы были просканированы при помощи компьютерного томографа Philips Ingenuity Elite 128 срезов по протоколам с разным напряжением (80, 100, 120, 140 кВ), силой тока (27–45, 166, 330–400 мА), толщи- ной среза (0,625, 1, 2,5, 3 мм).</p></sec><sec><title>Результаты</title><p>Результаты.

The syringes were placed at regular intervals into two phantoms: type 1 phantom – container filled with water; type 2 phantom – Chest Phantom N1 “LUNGMAN”. The phantoms were scanned with a Philips Ingenuity Elite CT 128 scanner using protocols with different voltages (80, 100, 120, 140 kV), amperage (27–45, 166, 330–400 mA), and slice thickness (0.625, 1, 2.5, 3 mm).</p></sec><sec><title>Results</title><p>Results. Density and Agatston indexes were obtained at different scanning parameters (voltage, amperage, slice thickness) for different factors of calcification density in both phantoms. The results are presented as a table with mean density values, standard deviation (SD), Agatston score of coronary calcium, and scanning parameters.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study demonstrates the influence of various scanning parameters on coronary artery calcium scoring results. The obtained information can be used in practice for more accurate quantification of coronary artery calcium, regardless of the scanning parameters.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>коронарный кальций</kwd><kwd>ультра-НДКТ</kwd><kwd>низкодозная компьютерная томография</kwd><kwd>скрининг рака легкого</kwd><kwd>факторы кальцификации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronary calcium</kwd><kwd>ultra-LDCT</kwd><kwd>low-dose computed tomography</kwd><kwd>lung cancer screening</kwd><kwd>calcification factors</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">Greenland P., Blaha M.J., Budoff M.J., Erbel R., Watson K.E.
