Abstract
Our newly designed image-guided radiotherapy (IGRT) system enables the dynamic tracking irradiation with a gimbaled X-ray head and a dual on-board kilovolt imaging subsystem for real-time target localization. Examinations using a computer-controlled three-dimensionally movable phantom demonstrated that our gimbals tracking system significantly reduced motion blurring effects in the dose distribution compared to the non-tracking state.
摘要
我们新设计的图像引导放疗（IGRT）系统采用万向 X 射线头和双机载千伏成像子系统实现动态跟踪照射，可实时进行靶区定位。使用计算机控制的三维可移动体模进行的检查表明，与非跟踪状态相比，我们的万向架跟踪系统显著降低了剂量分布中的运动模糊效应。
