图像引导放射治疗的临床应用

Clinical application of image- guided radiotherapy

图像引导放射治疗（IGRT）是继三维适形放疗（3DCRT）和调强适形放疗（IMRT）之后，又一新的放疗技术，是提高放射治疗精度、保证与控制放疗质量的重要手段。这一技术发展快，普及快，有很强的治疗优势。

Image-guided radiotherapy（IGRT） is a new radiation technique, following the three-dimensional eonformal radiotherapy （3D-CRT）and intensity-modulated radiotherapy （IMRT）. It is the important means to improve the accuracy and assure the quality of radiotherapy. IGRT develops and popularizes very quickly, and has superiority in treatment.
