图像引导放射治疗(ImageGuidedRadiationTherapy，IGRT)利用影像系统（EPID、CT等）实时修正因误差（如计划、摆位和器官运动等）所致靶区移位，充分考虑了器官和靶区放疗分次内和放疗分次间运动，利用先进的影像设备对肿瘤和关键器官进行监控，并能根据器官和靶区位置和形状变化调整治疗条件使照射野紧紧“追随”靶区，实现...
The primary goal of image‐guided radiation therapy (IGRT) is to minimize the difference between the actual delivered dose and the dose that was originally planned to be delivered. It has allowed an improved awareness of the magnitude of change that occurs in tumors and normal tissues during a...
Image guidance has become a central element of radiation therapy. While the use of images begins at the planning phase, recent technological developments allow high-performance imaging at the treatment unit on a fraction-by-fraction basis, and thereby, allow errors in the targeting of the ...
An image guided radiation therapy system comprises a radiation source to generate radiation. Radiation optics forms a therapeutic radiation beam from the therapeutic radiation from the radiation source. An imaging system forms an image of a target zone to control the radiation optics to direct the ...

The goal of radiation therapy treatment is to deliver the therapeutic dose to target volumes while reduce the radiation exposure to the adjacent normal structures. In the past, a large three-dimensional planning margin was utilized to account for geometric and setup uncertainties, which resulted in ...
