Study on Hybrid Multi-Objective Gradient Algorithm for Inverse Planning of IMRT

摘要：

Combining the intelligent optimization of multi-objective evolutionary algorithm and gradient algorithm, the hybrid multi-objective gradient algorithm is framed by real number. Test functions are used to analyze the efficiency of the algorithm. Under the simulation case of water phantom, the algorithm is applied to inverse planning process of IMRT (Intensity Modulated Radiation Treatment). The intensity profile obtained show that the hybrid multi-objective gradient algorithm can save a large amount of computing time with good Pareto frontier, can meet the requirements of practical applications.
