Провести количественный анализ качества планирования, оценить дозовые нагрузки на критические органы для этой категории пациентов.</p></sec><sec><title>Материал и методы</title><p>Материал и методы: Рассчитаны индексы гомогенности, конформности, оценены дозовые нагрузки в критических органах для планов облучения по технологии 3D конформной ЛТ (3D CRT) 23 пациенток РМЖ с имплантатами со встроенным металлическим портом. Расчеты проведены как с учетом (оконтуриванием) металлического порта и артефактов от него на КТ-изображениях, так и без учета.</p></sec><sec><title>Результаты</title><p>Результаты: По результатам анализа рассчитанных значений индексов конформности и гомогенности, доз в критических органах планов облучения 23 больных раком молочной железы показано, что наличие металлического порта и артефактов от него влияет на характер дозового распределения.</p></sec><sec><title>Выводы</title><p>Выводы: При создании 3D CRT плана облучения необходимо оконтуривать металлический порт и артефакты, а также присваивать истинные значения их плотностей.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: To evaluate the quality of radiation planning for breast cancer patients with implants with a built-in metal port.
