Abstract

The paper presents methods and results of a study of radiation-physical characteristics of inhibitory radiation beam with the Grenz energy of 15MeV generated by an electron linear accelerator LUE-15M. Special emphasis is laid on primary dosimetric information used for the planning of radiotherapy: depth doses, beam profiles, dose functions of a collimated beam. It has been shown that in general the accelerator meets the requirements of the International Electrotechnical Commission. General error in the focal absorbed dose at the expense of variable parameters of the accelerator was evaluated. It does not exceed +/- 3.5%.

摘要

本文介绍了对由电子直线加速器LUE - 15M产生的能量为15MeV的境界射线束的辐射物理特性进行研究的方法和结果。特别强调了用于放射治疗计划的主要剂量学信息：深度剂量、射野轮廓、准直束的剂量函数。结果表明，该加速器总体上符合国际电工委员会的要求。评估了由于加速器可变参数导致的焦点吸收剂量的总体误差。该误差不超过±3.5%。
