We report on the use of the Monte Carlo simulation code GEANT for two different applications in the field of particle beam therapy. The first application relates to the planning of intensity-modulated proton therapy (IMPT) treatments. An important issue is thereby the accurate prediction of the dose while irradiating complex inhomogeneous patient geometries. We developed an improved method to account for tissue inhomogeneities in pencil beam algorithms. We show that GEANT3 can be successfully used to validate the new model before its integration in our treatment planning system. Another project concerns the investigation of the potential of high-energy particles produced by laser-plasma interactions for radiotherapy. GEANT4 simulations of the dosimetric properties of an experimental laser-accelerated electron beam were performed. They show that this technique may be very attractive for the development of new therapy beam modalities such as very-high energy (170 MeV) electrons.
