Целью данного исследования являлась оценка эффективных доз при проведении интервенционных исследований на примере баллонной пластики пищевода, которую выполняли педиатрическим пациентам в возрасте от 1 до 2 лет на базе отделения рентгенохирургических методов диагностики и лечения Санкт-Петербургского государственного педиатрического медицинского университета. Модели облучения пациентов были разработаны на основе собственных данных. Расчет эффективных и органных доз пациентов, нормированных на значение произведения дозы на площадь, измеренного в ходе исследования, проводился с помощью программного обеспечения PCXMC 2.0. Значения коэффициентов перехода от произведения дозы на площадь к эффективной дозе, определенные с использованием тканевых взвешивающих коэффициентов из Публикаций МКРЗ 60 и 103, составили 10,7 и 11,7 мкЗв/сГр х см2 соответственно. Результаты верификации метода оценки эффективных доз на примере баллонной пластики пищевода показали, что использование несоответствующих коэффициентов перехода может приводить к недооценке эффективных доз детей в несколько раз. Различия в значениях коэффициентов перехода от произведения дозы на площадь к эффективной дозе значительны и объясняются разницей в исходных параметрах используемого ангиографического аппарата, используемых параметрах напряжения, расстояния источник – приемник и размера поля облучения на самом пациенте. Для конкретной рассмотренной процедуры была предложена упрощенная модель облучения пациентов, описываемая одним полем облучения. Оценка эффективных доз с использованием многопольной и однопольной модели показала сопоставимые результаты, что позволяет в похожих случаях использовать дифференцированный подход к оценке доз облучения пациентов.</p></abstract><trans-abstract xml:lang="en"><p>Interventional examinations are associated with high levels of patient exposure per examination, which makes it particularly important to monitor individual patient doses and to assess radiation risks. The aim of this study was the assessment of effective doses for fluoroscopy-guided balloon dilatation of benign esophageal strictures, whichwasperformedonpediatricpatientsaged 1 to 2 yearsatthe Departmentof Radiosurgical Methodsof Diagnosis and Treatment of St. Petersburg State Pediatric Medical University. Patient exposure patterns were basedonourowndatacollection.    Thecalculationofeffectiveandorgandosesofpatientsnormalizedbythevalue of the dose area product measured during the study was carried out using PCXMC 2.0 software. The conversion coefficients from the dose area product to the effective dose were calculated using tissue weighting coefficients from the ICRP Publications 60 and 103 their values were 10.7 and 11.7 µSv/cGy cm2, respectively. The results of verification of the method indicated that the use of inappropriate conversion coefficients leads to an almost double underestimation of children’s effective doses. Differences in the values of conversion coefficients are significant and are explained by differences in voltage, source to image distance, and irradiation field size. A simplified model of patient exposure was proposed, which is described by a single irradiation field. The assessment of effective doses using multi-field and single-field irradiation model shows comparable results, which allows using the differentiated approach to the assessment of radiation doses of patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эффективная доза</kwd><kwd>коэффициенты перехода</kwd><kwd>интервенционные исследования</kwd><kwd>дети</kwd><kwd>медицинское облучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>effective dose</kwd><kwd>conversion coefficients</kwd><kwd>interventional examinations</kwd><kwd>children</kwd><kwd>medical exposure</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">ICRP Publication 117.
