摘　　要：For resolving the problem that a conventional intensity modulated radiotherapy （IMRT） plan designed with the ＂two-step method＂-creates a greater number of apertures and total Monitor Units （MU）, the direct aperture optimization （DAO） method using a genetic algorithm and conjugate gradient was studied based on Accurate/ Advanced Radiation Therapy System （ARTS） developed by the FDS Team （www.fds.org.cn）.For resolving the problem that a conventional intensity modulated radiotherapy （IMRT） plan designed with the ＂two-step method＂-creates a greater number of apertures and total Monitor Units （MU）, the direct aperture optimization （DAO） method using a genetic algorithm and conjugate gradient was studied based on Accurate/ Advanced Radiation Therapy System （ARTS） developed by the FDS Team （www.fds.org.cn）.
