摘　　要：目的:本文根据调强放射治疗的研究现状,结合最优化方法,对IMRT中射野强度(通量)模型进行了深入研究。方法:详细介绍了剂量计算模型与强度(通量)优化模型,并在此基础上对我科cms与pinnacle放射治疗计划系统的优化方式进行对比。结果:pinnacle放射治疗计划系统的优化模型时间效率更高。结论:通过深入了解放射治疗计划系统的优化方式,为临床实际工作作出理论指导,并为下一阶段的自主软件开发提供技术支持。Objective： To further study the beam intensity（flux） models for the intensity-modulated radiation therapy on the basis of present research status. Methods： The optimization models for dose calculation and beam strength（flux） were introduced, and the optimization models for cms and pinnacle radiation therapy planning system in our department were compared. Results： The optimization model for radiation therapy planning system had higher time efficiency than that of cms. Conclusion： Studying the optimization model for radiation therapy planning system, could make theoretical guidance for clinical practice and provide theoretical support for the next phase of software development.
