Language requirements
Proficiency in English
Academic requirements
Candidates with experience in medical physics would be ideal. Prerequisites are good programming knowledge (C++, Geant4, python) and knowledge of the physics of particle therapy. Familiarity with medical imaging topics would be desirable. This can be expected from a physics graduate student, who had ideally worked on a topic related to medical radiation physics in their master thesis. Equivalent engineering backgrounds may also be compatible.

Project description

In ion therapy of cancer, beams of protons or heavier ions are used to treat tumors while sparing healthy tissue by exploiting their finite range. Accurate prediction of this range is performed using tomographic images acquired with the same ions; as opposed to using x-ray computes, tomography (CT) images that require look up table conversion to relative stopping power (RSP) and introduce uncertainties. This project will aim at comparing proton and helium CT and evaluate the real world impact on therapeutic close distributions. The project will make use of the Monte Carlo simulation platform of the LMU, which models the real-world US proton CT collaboration scanner with high fidelity. Simulated proton and helium CT scans in both ideal and real-world conditions of clinical patient system Raystation to assess the impact on treatment planning of the image quality of the different ions, and to determine the optimal safety margins for use in robust treatment planning.
