Possible Theses in the SiFi-CC Project

Ion therapy is a very precise tool in cancer treatment because of its characteristic longitudinal dose profile (Bragg peak). To optimize the precision of ion therapy, a real-time monitoring of the longitudinal Bragg peak position is needed. A promising approach towards online range verification in ion therapy is the analysis of prompt gamma radiation emitted by several nuclear processes. In our group a SiPMs and scintillating fiber-based Compton Camera (SiFi-CC) has been developed. This camera will record the prompt gamma radiation and will be able to reconsturct the position of the bragg peak. The project is a close international collaboration  with the Jagiellonian University Krakow as well as the University of Katowice (Poland).

On the SiFi-CC project, we offer master and bachelor theses on request. Topics include

  • data analysis and
  • simulation.

Most of the theses include parts from more than one of these areas. A collection of currently available topics can be downloaded here.


Data Analysis

We develop an analysis and evaluation framework based on simulation of the SiFi-CC. This framework includes all steps that are necessary to extract the Bragg peak position from the data that a real detector would deliver. Your task would be to implement a neuronal network for the event identification and to compare the resulting event classification with the current one. Another task would be to apply the principle of a Single Plane Compton Camera to the two modules of the SiFi-CC and to extend the reconstruction with the so gained information.



For all our experiments a simulation in Geant4 is performed for a better understanding and comparison of measurement results. Additionally it is a good possibility to plan and optimize detectors.

Your task could be to extant the simulation of the SiFi-CC by an active vetodetector or a passiv shield or to determine the secondary radiation of a patient via a detailed simulation of a human body. Furthermore you could explore the feasibility to use a tracer that accumulates in the tumor to enhance the prompt gamma production or to produce characteristic energy lines. Geant4 is based on C++, so it is advantageous if you have some experience with it.
