Anthropomorphic phantoms and Geant4-based implementations for dose calculation

Various models of anthropomorphic phantoms have been developed in the past decades for usage in Monte Carlo simulation for radiation protection and other medical physics applications; they adopt two alternative approaches, either modeling the body components through analytical geometrical representations or through voxelized geometries. An original system has been developed in the context of the Geant4 simulation toolkit. It exploits Geant4 advanced capabilities to model geometrical components and the object oriented technology to provide a variety of models of the human body usable in a simulation application. A design allows the creation of analytical or voxel phantoms of different sex and age. Phantoms based on established models are provided. The presented results are preliminary.
