Building a Better Phantom: A Tetrahedral Mesh for Chinese Women

January 28, 2025

Creating detailed surface phantoms of Chinese women of childbearing age is great, but they can't be used directly in Monte Carlo simulations. Instead, these surface phantoms have to be turned into voxel phantoms, which might lose some of their initial advantages. So, the goal of this study is to bui
