ATOM-MIRD Hybrid Voxel Model for Monte Carlo Calculations of Organ Doses: A Complement to a Physical Phantom

초록

In this study, a hybrid voxel model was constructed by combining the voxel model of the ATOM adult male phantom with the organ models of the MIRD5 mathematical phantom. The organ models of the mathematical phantom were successfully transferred to the hybrid model, replicating the sizes of the organs within a 3% difference. Consequently, a total of 14 main radiosensitive organs were defined in the hybrid model. The developed model was implemented into a Monte Carlo particle transport simulation code, MCNPX, and used to calculate the organ doses, which were then compared with the TLD measured values.
