Исследование выполнено на 64-срезовом компьютерном сканере Toshiba Aquilion 64 с использованием антропоморфного тканеэквивалентного фантома с параметрами взрослого пациента массой 73,5 кг и термолюминесцентных дозиметров с детекторами с ДТГ-4 на основе кристаллического LiF. Детекторы размещали в местах расположения органов и тканей при стандартных протоколах компьютерной томографии двух сочетанных областей тела: 1) органы грудной клетки, брюшной полости и малого таза; 2) органы брюшной полости и малого таза. При вычислении эффективной дозы облучения использовали взвешивающие коэффициенты ткани по НРБ-99/2009 и по Публикации 103 МКРЗ.</p><p>Результаты исследования и обсуждение: Наибольший вклад в эффективную дозу облучения выявлен для гонад, красного костного мозга, толстого кишечника, лёгких и желудка (в сумме 71,8 – 76,2 %). Установлено, что эффективные дозы облучения пациентов, рассчитанные по результатам фантомной дозиметрии, больше значений полученным по данным DLP на консоли компьютерного сканера при использовании взвешивающих коэффициентов ткани по Публикации 103 МКРЗ для области 1 в 1,12, для области 2 – в 1,13 раза, по НРБ-99/2009, соответственно, – в 1,30 и в 1,38 раза. Заключение: При компьютерной томографии дозиметрия на антропоморфном тканеэквивалентном фантоме термолюминесцентными дозиметрами демонстрирует несколько более высокие дозы облучения по сравнению со значениями доз, рассчитанных по DLP на консоли. Это свидетельствует о важности периодического сопоставления доз облучения пациентов, рассчитанных по DLP на консоли томографа, с дозами, зарегистрированными в ходе прямой дозиметрии при реальных условиях компьютерной томографии в отделениях и центрах лучевой диагностики.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to perform phantom dosimetry of organs and tissues to assess effective radiation doses to patients during computed tomography of combined areas of the body and calculated based on the readings on the scanner console.</p><sec><title>Materials and Methods</title><p>Materials and Methods: The study was performed on СT-scanner Toshiba Aquilion 64 an anthropomorphic tissue-equivalent phantom weighing 73.5 kg using thermoluminescent detectors located in the locations of organs and tissues, under standard computed tomography protocols of two combined body regions: 1 – organs of thorax, abdomen and pelvis; 2 – organs of abdomen and pelvis. The effective radiation dose was calculated using tissue weighting factors according to NRB-99/2009 and ICRP Publication 103 recommendations.</p></sec><sec><title>Results and Discussion</title><p>Results and Discussion: The largest contribution to the total radiation dose was found for the gonads, red bone marrow, colon, lungs and stomach (71.8-76.2% in total). It was established that the effective radiation doses to patients during computed tomography, calculated based on the results of phantom dosimetry with TLD detectors, are higher than the values obtained from DLP data on the console of a computer scanner using tissue weighting factors according to ICRP Publication 103 for CT-1 by 1.12 times, for CT-2 by 1.13 times, according to NRB-99/2009 for CT-1 by 1.30 times, for CT-2 by 1.38 times.</p></sec><sec><title>Conclusion</title><p>Conclusion: Dosimetry on an anthropomorphic tissue-equivalent phantom demonstrates higher patient radiation doses during computed tomography compared to dose values calculated by DLP on the computed tomography scanner console. This demonstrates the importance of periodically comparing patient doses calculated by DLP on the computed tomography scanner console with doses recorded by direct dosimetry under real computed tomography scanning conditions in radiology departments and centers.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>отделения и центры лучевой диагностики</kwd><kwd>радиационная безопасность</kwd><kwd>фантомная дозиметрия</kwd><kwd>термолюминесцентные детекторы</kwd><kwd>эффективная доза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computed tomography</kwd><kwd>departments and centers of radiation diagnostics</kwd><kwd>radiation safety</kwd><kwd>phantom dosimetry</kwd><kwd>thermoluminescent detectors</kwd><kwd>effective dose</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование не имело спонсорской поддержки</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was not supported by sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Valentin J., International Commission on Radiation Protection.
