New calculation method for 3D dose distribution in tetrahedral-mesh phantoms in Geant4
The tetrahedral-mesh (TM) geometry, which is a very promising geometry for computational
human phantoms, has a limitation in 3D dose distribution calculation for medical
applications. Even though Geant4 provides the read-out geometry for calculating 3D dose
distribution in the TM geometry, this method significantly slows down the computation speed.
In the present study, we developed a new method, called Moving Voxel-based Dose-
Distribution Calculator (MVDDC), to rapidly calculate a 3D dose distribution in a TM …
