Перечислены основные ошибки и неопределенности, возникающие в ходе планирования дозового распределения и в процессе доставки дозы. Рассмотрены способы сравнения и сопоставления дозовых распределений: критерий расстояния (DTA) и тест на алгебраическую разность доз. Приведены формулы для расчета смещения точек дозовых распределений, а также минимального значения смещения точек. Определено влияние глобальной и локальной нормализации и пространственного разрешения на интерпретацию полученных результатов. Разработана методология определения обоснованных критериев γ-анализа индивидуальных дозовых распределений при проведении верификации планов облучения онкологических пациентов с применением методов высокотехнологичной лучевой терапии. Использование предложенной авторами процедуры для установления уровней действия и допусков позволит оценить качество оказываемой медицинской помощи в учреждениях здравоохранения при применении методов высокотехнологичной лучевой терапии.</p></abstract><trans-abstract xml:lang="en"><p>A typical process for verification of treatment plans in intensity-modulated radiation therapy is described. The main errors and uncertainties that arise in the course of planning dose distribution and in the process of dose delivery are listed. Methods for comparing dose distributions are considered: the distance to agreement (DTA) and the test for the algebraic dose difference. Formulas for calculating the shift of points of dose distributions, as well as the minimum value of the shift of points, are provided. The influences of global and local normalization and spatial resolution on the interpretation of the results obtained are defined. A methodology for determining reasonable criteria for gamma-analysis of individual dose distributions when verifying plans for irradiation of cancer patients using high-tech radiation therapy methods has been developed. Using the procedure proposed by the authors to establish action limits and tolerances will make it possible to assess the quality of medical care provided in healthcare institutions when using high-tech radiotherapy methods</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лучевая терапия</kwd><kwd>IMRT</kwd><kwd>VMAT</kwd><kwd>гарантия качества</kwd><kwd>верификация</kwd><kwd>γ-анализ</kwd><kwd>доза</kwd><kwd>допуски</kwd><kwd>уровни действия</kwd><kwd>медицинская физика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiation therapy</kwd><kwd>IMRT</kwd><kwd>VMAT</kwd><kwd>quality assurance</kwd><kwd>verification</kwd><kwd>gamma-analysis</kwd><kwd>dose</kwd><kwd>tolerances</kwd><kwd>action limits</kwd><kwd>medical physics</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">Tolerance limits and methodologies for IMRT measurement-based verification QA: Recommendations of AAPM Task Group No. 218 / M.
