Recent Advances in Computational Human Phantom for Monte Carlo Dose Calculation

초록

In the present paper, an advanced type of a computational human phantom called PSRK-Man (Polygon Surface Reference Korean-Man) is introduced with its advantages over the traditional voxel phantom. This paper also discusses the computation speed issue of the surface phantom and the implementation of the direct accelerated geometry Monte Carlo (DAGMC) toolkit in Geant4, which makes the computation speed of the surface phantom by 20-30 times. With the computation speed problem solved, the surface phantom can be used in many applications, including medical imaging, accurate charged particle dosimetry, and radiation therapy simulations.
