Abstract

Although the Boundary Representation (BREP) method creates detailed surface phantoms of Chinese women of childbearing age, these phantoms cannot be directly used in Monte Carlo simulations. They must first be converted into voxel phantoms, a process that may diminish some of the inherent advantages of the surface phantoms. Therefore, the aim of this study is to construct a tetrahedral mesh (TM) phantom of Chinese women of childbearing age based on the BREP phantom, incorporating micron-level structural refinements to certain organ tissues while maintaining the original model's structure. This TM phantom can be directly implemented into Monte Carlo codes to calculate the absorbed dose at different photon energies, demonstrating that both the structure and position of organ tissues affect the radiation dose. By achieving more accurate dose assessments, we can optimize radiation protection measures and reduce the potential risks to women of childbearing age.&#xD.
