Сопоставлены количественные характеристики планов облучения 35 пациентов раком только средней трети пищевода. Для этого использованы индексы гомогенности и конформности дозы в пределах мишени, гистограммы доза—объем и дозовые нагрузки на критические органы для технологий 3D CRT, IMRT, RapidArc. Сравнение проведено для двух моделей ускорителей Clinac iX (Varian) и Halcyon (Varian). Сопоставлены результаты расчетов планов облучения с использованием различных версий и алгоритмов расчета СП.</p></sec><sec><title>   Результаты</title><p>   Результаты: Сопоставление количественных характеристик планов облучения позволило обозначить технологию IMRT как предпочтительную при лечении рака пищевода на ускорителях обоих типов, с внешним и с встроенным гантри. При этом влияние алгоритмов расчета и версий СП на показатели индексов гомогенности, конформности и дозовые нагрузки на критические органы не выражено, а результаты расчетов сопоставимы в пределах погрешности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Purpose</title><p>   Purpose: To compare the quality of irradiation planning for patients with esophageal cancer using Clinac iX (Varian) electron accelerators with external gantry and Halcyon (Varian).

The comparison was carried out for two models of accelerators Clinac iX (Varian) with an external gantry and tunnel type Halcyon (Varian). The results of calculations of irradiation plans using different versions and algorithms for calculating planning systems are compared.</p></sec><sec><title>   Results</title><p>   Results: A comparison of the quantitative characteristics of the exposure plans made it possible to designate the IMRT technology as the preferred one in the treatment of esophageal cancer using accelerators of both types, with external and built-in gantry. At the same time, the influence of calculation algorithms and versions of the SP on the indices of homogeneity, conformity and dose loads on critical organs is not expressed, and the calculation results are comparable within the error.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лучевая терапия</kwd><kwd>рак пищевода</kwd><kwd>линейные ускорители электронов</kwd><kwd>планирование облучения</kwd><kwd>количественная оценка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiotherapy</kwd><kwd>esophageal cancer</kwd><kwd>linear electron accelerators</kwd><kwd>radiation planning</kwd><kwd>quantification</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study had no 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">Ajani JA, D’Amico TA, Bentrem DJ, et al.
