研制一种肿瘤放射治疗挡铅托盘,主要是针对西门子加速器没有配备电动多叶光栅条件下,实现适形放射治疗。从实用角度出发,不依靠进口,降低成本,做到简单方便。为提高适形放射治疗精度,把工作重点放在制定治疗计划和模室制作过程。 Development of a tumor radiotherapy block lead tray, mainly for Siemens accelerator is not equipped with electric multi-leaf grating conditions, to achieve conformal radiotherapy. From a practical point of view, do not rely on imports, reduce costs, be simple and convenient. In order to improve the accuracy of conformal radiotherapy, the emphasis is placed on the development of treatment plans and mold room production processes.
