Geant4 for medical physics applications

Page currently under revision

These web pages provide information about the use of Geant4 in medical physics. They are maintained by the Geant4 Collaboration. Please contact Sebastien Incerti and Susanna Guatelli if you would like to include information and to provide feedback.

Where to start from

Once Geant4 is installed, beginners are recommended to get practice with Geant4 by means of the basic examples to understand the fundamental functionality of Geant4 (e.g. geometry, physics, scoring, UI, analysis, visualisation). Users can refer to many extended and advanced examples to use Geant4 in medical physics applications.

Physics, geometry and tracking

• Navigation
• Physics
• Biasing
• CPU performance
• Reverse Monte Carlo
• Interfaces (phase spaces, anatomy/dose rendering)

Radiobiology: Geant4-DNA extensions

Geant4 Physics electromagnetic processes are available for the simulation of particle interactions down to the electronVolt and molecular scale in liquid water, the main component of biological medium. Developments are on-going in the framework of the Geant4-DNA project, initiated by P. Nieminen ( European Space Agency/ESTEC) in order to model Physics, Chemistry and Biology processes for the simulation of biological effects of ionizing radiation.

A description of the Geant4-DNA project and it status is accessible directly from this link.

It is part of a larger development activity, the development of Physics Models for Biological Effects of Radiation and Shielding , as detailed here.

Selected references can be found here.
