摘　　要：利用多叶准直器(MLC)叶片运动可以实现各种不同方式的调强照射,目前越来越多的放疔中心应用它实施调强放射治疗,为了达到更好的治疗效果,需要有科学、严格的质量保证(QA)和质量控制(QC)措施来保证调强放疗的实施和治疗精度。The multileaf collimator （MLC） to achieve beam-intensity modulation is used more and more in most radiotherapy center. The various approaches to modulation have been developed that use the motion of the MLC leaves during irradiation to create a dynamic compensating filter either for a number of fixed gantry exposures or for a continuous arcing fan beam and for a continuous arcing cone beam. In order to obtaining much better therapeutic effect, we must have a strict scientist quality assumanee（QA） and quality control（QC） management of MLC in intensity modulated radiation theran.
