[Dose distribution in combined radiotherapy of endometrial cancer using an "Agat-B" apparatus].
The paper is devoted to a comparative analysis of dose distributions occurring during combined radiation therapy of patients with endometrial cancer. A dosimetric analysis has shown that the level of absorbed doses in a primary tumor focus is most adequately evaluated with taking due account of dose exposures in points M but not in points A. Besides it was established that the level of radiation exposure in the irradiated organ can be changed by the individual selection of schemes for the intracavitary placement of 60Co sources of higher activity. A comparative analysis of dose distributions occurring in different methods of gamma-beam irradiation of patients was made. It has been shown that the use of the shaped fields of matrix formation provides optimum dose distribution in pathological foci and organs neighbouring with the uterus.
