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.
