My current work as a PhD-student at CERN consists of investigations
concerning the usage of modern software tools for determining the spatial
dose distribution in patients subject to radiotherapy with ion beams. In
this context I employ Monte Carlo Methods and distributed computing
techniques (particularly Grid) to achieve a high precision and fast
computations suitable to clinical applications. My work involves the
quantitative assessment of relevant physics models for low-energetic ions
(as occuring in radiothereupical applications), currently available in the
Geant4 Simulation Toolkit. Both electromagnetic and hadronic interactions
are taken into account. Possible extensions of the existing Geant4 physics
are considered to design and implement new or improved models. An important
part of my thesis is to evaluate the possibility to exploit a distributed
computing environment for achieving a precise dose calculation within a time
frame compatible with clinical applications at a hadrontherapy facility. For
this purpose I perform large-scale Geant4-based dose calculations on the
LCG. |
