我们新设计的图像引导放射治疗（IGRT）系统，使动态跟踪照射与万向架X射线头和双板上的千伏成像子系统的实时目标定位。使用计算机控制的三维可移动体模的检查表明，与非跟踪状态相比，我们的平衡环跟踪系统显著降低了剂量分布中的运动模糊效应。(C)2009爱思唯尔爱尔兰有限公司保留所有权利。放射治疗与肿瘤学93（2009）45 - 49
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.
