Приведено описание оригинальной конструкции фантома для проведения верификации планов облучения при использовании динамических методов дистанционной лучевой терапии, позволившего разработать методику проведения кросс-калибровки комплексных дозовых распределений, основанной на однократном измерении стабильных во времени значений калибровочных коэффициентов,  что обеспечивает необходимую  реализацию запланированного распределения поглощённой дозы, сокращает продолжительность подготовки к проведению сеансов облучения пациентов и увеличивает пропускную способность ускорителя

The design of special verification phantom for dynamic radiotherapy checking is described. This phantom permits to insert the dose distribution cross-calibration before every days patients irradiation on Linac with RapidArc. Cross-calibration factor is defined by approximation of large number correction factors measured in phantom at different angles of gantry rotation and middle quantity calculation. The long range stability of all correction factors have been evaluated during checking of setting treatment plans and did not exceed 1 %. The fast checking of patient’s dynamic irradiation with developed method gives possibility texactly realize of planning dose distribution and to increase the capacity of accelerators.
