标准摘要
[中文适用范围]: 补充:本专用标准适用于放射治疗模拟器: ——使用诊断X射线设备物理模拟放射治疗辐射束,以便可以定位放射治疗期间要接受照射的治疗体积,以及放射治疗的位置和大小可以确认辐射场; - 专门用于放射治疗模拟,作为预期放射治疗的前奏,而不用于任何其他目的,例如一般诊断检查; - 在技术说明中规定的环境和供电条件下使用; - 包括以下部分: · 用于产生 X 射线束的系统,该系统模拟放射治疗辐射束的几何形状; · 一种用于产生所传输的 X 射线束图像的系统,例如通过射线照相或射线透视; · 控制辐射束的尺寸和位置并描绘预期治疗区域的组件; · 物理模拟放射治疗设备的几何形状和运动并支持成像系统的机械结构; · 患者支持系统。 [外文原描述]: Applies to radiotherapy simulators: - that use diagnostic X-ray equipment to simulate physically a therapeutic radiation beam, so that the treatment volume to be subjected to irradiation during radiotherapy can be localized, and the position and size of the radiotherapy radiation field can be confirmed; - intended exclusively for radiotherapy simulation as a prelude to intended radiotherapy, and not for any other purpose such as general diagnostic examinations. Establishes requirements to ensure the ionizing radiation safety and enhanced mechanical and electrical safety of radiotherapy simulators; it identifies geometrical parameters that are critical for the accurate simulation of a radiotherapy treatment. Cancels and replaces the first edition published in 1993 and its amendment 1 (1996).
