The integration of on‐board imaging (OBI) with linear accelerators paved the way for Image Guided Radiation Therapy (IGRT) as it is practiced today in the clinic. The advent of IGRT is a major milestone in the history of radiotherapy. The main goal of image guidance in radiotherapy is to improve radiation treatment delivery via superior localization and tracking of target cancer cells. IGRT is hence integral to accurate, precise and safe delivery of radiotherapy.

治疗验证成像

车载成像（OBI）与线性加速器的集成为当今临床实践中的影像引导放射治疗（IGRT）铺平了道路。IGRT的出现是放射治疗史上的一个重要里程碑。放射治疗中影像引导的主要目标是通过对靶癌细胞的卓越定位和跟踪来改善放射治疗的交付。因此，IGRT是准确，精确和安全地进行放射治疗不可或缺的部分。
