Abstract：Stereotactic ablative radiation therapy is one of representative precise radiotherapy technology and has characteristics of precise simulation, accurate delivery, good performance and minimal adverse effect, which has acquired similar results with surgery in the treatment of brain metastasis and early stage non-small cell lung cancer. During the precise delivery management, the image-guided technologies play an important role, which include single imaging system and the combination of imaging system. The former are guided by ultrasound, electron beam, cone beam computer tomography (CT), fan beam CT, nuclear magnetic image and electromagnetic tracking technology; the latter are guided by ExacTrac X-ray six dimensional directional guidance system, etc. This article will review current application of image-guided technology and analyze imaging principle and how to improve the accuracy and shrink surrounding normal tissues irradiated volume, explore the future development.
