摘　　要：准确的靶区勾画对提高肿瘤局部控制率及降低正常组织并发症率有着至关重要的意义,医学成像设备及图像融合技术的发展为准确定位放疗计划靶区提供了可能。本文综述了图像融合技术在放疗中的应用,并对解剖成像及功能成像的现状进行阐述,同时展望了多种融合图像应用于放疗技术的前景与挑战。The accuracy of target volume delineation prior to radiotherapy is essential for improving the local control rate of tumors as well as reducing the complication probability of normal tissues. Medical imaging equipment and image fusion technologies are useful to accurately delineate the target volume in the planning of radiation therapy. This study reviewed the application of image fusion technologies in radiotherapy, and the status quo of anatomical imaging and functional imaging was clariifed. Finally this paper discussed the prospects and challenges of a variety of image fusion technologies in the application of radiotherapy.
