Messung der Hautdosis unter Strahlentherapie – insbesondere bei Patienten mit Gewichtsverlust
In radiotherapy the skin of the patient is naturally spared by the build-up-effect of megavoltage X-ray beams, which avoids side effects like skin irritations or even fibrosis. However, there are some uncertainties to the predicted skin dose: some patients are treated with intensity-modulated radiation therapy (IMRT) using dose calculation algorithms which lack accuracy at the boundary layer i.e. in the skin region of the patient. And some patients suffer weight loss and the irradiated volume shrinks compared to the pre-treatment simulation. In this thesis you can gain an insight into clinical medical physics and accompany a phantom patient from start (computed tomography for treatment planning) until finish (radiation therapy at the linear accelerator). The goal is to measure accurate skin dose with radiochromic films and to develop a realistic skin model which can also emulate weight loss i.e. volume reduction of a patient. Results can help physicians to estimate realistic skin doses and to decide upon re-planning of treatment plans for patients. Contact: Frauke Alexander,, 089-4140-9428

Nanodosimetrie in der Neutronentherapie
The FRM II at TUM has a facility for radiation therapy of malignant tumours using highly effective fast neutrons. Within a feasibility study we want to investigate if nanodosimetric methods can be integrated into a treatment planning software for neutrontherapy. Nanodosimetry counts ionisations in volumes of the size of a DNA segment and is a promising approach to perform biologically optimized treatment planning. A fundamental step towards treatment plan optimization are realistic weighting factors for nanodosimetric particle track properties in a voxel geometry i.e. a macroscopic volume used in treatment planning. By comparing simulation results to the result calculated with weighting factors and the known particle spectrum hitting the voxel we want to study if this approach is feasible for treatment planning based on nanodosimetry.
