| Research Abstract |
A Monte Carlo dose calculation system has been developed to account for double dynamic systems, which are dynamic intensity-modulated (IM) beam delivery based on MLC movement and respiratory organ motion.
The Monte Carlo simulation reproduced the dynamic IM beam delivery. The dose distribution calculated using 4DCT was verified and showed good agreement with film measurements. The dose distributions of pancreas IMRT plans were calculated and the effects of the direction of respiratory motion and respiratory amplitude on dose distribution were revealed.
