Верификация плана лучевого лечения позволяет оценить соответствие дозового распределения, доставленного к мишени, запланированному распределению с погрешностью результата облучения, не превышающей заданную величину критерия приемлемости. Разработаны инструментальные средства для оценки трехмерного дозового распределения планов лучевой терапии с модуляцией интенсивности, используя величину абсолютной дозы облучения. Проведен анализ существующих технических средств и методик проведения верификации планов лучевой терапии на медицинских линейных ускорителях электронов, а также выявлены их недостатки. Показано, что данные методики осуществления верификации трехмерного дозового распределения не дают точного представления об абсолютных значениях дозы излучения в мишени. Предложены система и метод, позволяющее повысить точность проведения верификации плана лучевой терапии за счет использования полученного кросс-калибровочного коэффициента определяемого с учетом значения радиационного выхода медицинского линейного ускорителя непосредственно в момент осуществления как данной процедуры, так и сеанса лучевой терапии, а также способ проведения верификации плана лучевой терапии с их применением.</p></abstract><trans-abstract xml:lang="en"><p>The effectiveness of the use of modern technologies and methods of radiation treatment depends on the means of quality control of the operational parameters of the radiotherapy equipment. The development of technical means for verification of the radiation therapy plan, allowing accurate assessment of the three-dimensional dose distribution in the target, is a priority task when introducing innovative methods of radiation treatment. The aim of the work is to develop tools for assessing the three-dimensional dose distribution of radiation therapy plans with intensity modulation using the magnitude of the absolute radiation dose. The authors analyzed the existing technical means and methods for verifying radiation therapy plans on medical linear electron accelerators, and also identified their shortcomings. It is shown that these techniques for verifying the three-dimensional dose distribution do not give an accurate idea of the absolute values of the radiation dose in the target. A system and a method are proposed that allows improving the accuracy of the verification of the radiation therapy plan by using the obtained cross-calibration coefficient determined taking into account the value of the radiation output of the medical linear accelerator immediately at the time of the implementation of both this procedure and the radiation therapy session, as well as a method for verifying the plan radiation therapy with their use.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лучевая терапия</kwd><kwd>линейный ускоритель электронов</kwd><kwd>верификация</kwd><kwd>модуляция интенсивности</kwd><kwd>доза излучения</kwd><kwd>трехмерное дозовое распределение</kwd><kwd>радиационный выход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiation therapy</kwd><kwd>linear electron accelerator</kwd><kwd>verification</kwd><kwd>intensity modulation</kwd><kwd>radiation dose</kwd><kwd>three-dimensional dose distribution</kwd><kwd>radiation output</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">Тарутин, И.
