摘　　要：调强放疗(IMRT)是目前最常应用的一种高精度放疗技术,对照射靶区的准确性要求高,若照射靶区出现移动将会极大影响其准确性,降低其治疗效果,增加肿瘤复发率和放疗并发症的发生。摆位误差是影响照射靶区移动的关键因素之一,在实现IMRT的精准性中起着重要作用。所以,如何监测和减少摆位误差成了研究热点。多种技术和方法的应用,使得摆位误差得到较好控制,同时也使患者得到了更佳的疾病控制和更轻的不良反应。该文将对各种技术和方法在摆位误差方面的研究作一综述。Intensity modulated radiation therapy(IMRT)is one of the most frequently used high-precision radiotherapy techniques,which requires high accuracy of the target area.If the target area of irradiation moves,its accuracy will be greatly affected,the therapeutic effect will be reduced,and the recurrence rate of tumor and the incidence of radiotherapy complications will be increased.The setup error is one of the key factors affecting the target area movement and plays an important role in realizing the precision of IMRT.Therefore,how to monitor and reduce the setup error has become a research hotspot.The application of various techniques and methods makes the setup error better controlled,and also makes the patients get better disease control and less adverse reactions.This article reviews the various techniques and methods for the study of setup errors.
