A time- and space-saving Monte Carlo simulation method using post-collimation generative adversarial network for dose calculation of an O-ring gantry Linac

An accurate beam model is critical for Monte Carlo (MC) simulation in radiation therapy studies. Among the various beam modeling techniques, the phase space source stands out as one of the most reliable options [1]. This method records particle properties, including energy, type, position, and direction, at a desired surface or volume in space. Achieving an acceptable simulation uncertainty necessitates a substantial number of primary particles from the phase space source, leading to storage requirements ranging from gigabytes (GB) to terabytes (TB), depending on the simulation task [2].
