Modelling of Brainstem Toxicity Including Variable Relative Biological Effectiveness in Paediatric Proton Therapy
(Master thesis, 2021-06-01)Brainstem necrosis is a rare but severe side-effect following paediatric proton therapy. Substructures of the brainstem may be associated with regional differences in radiosensitivity, but these are not accounted for ... -
Models for the relative biological effectiveness in proton therapy: on the impact of cell-irradiation design
(Master thesis, 2020-07-07)Background: The use of protons was first suggested for use in treating cancer in 1946, due to its preferable dose distribution. In clinical practice, a constant Relative Biological Effectiveness (RBE) of 1.1 is used in ... -
Monte Carlo simulations of neutron based in-vivo range verification in proton therapy – optimization of detector dimensions and positioning
(Master thesis, 2019-12-06)Proton therapy is a cancer treatment modality expanding in clinical applications around the world. Due to the finite range of a monoenergetic proton beam, it is possible to spare more of the healthy tissue surrounding the ... -
Monte Carlo Simulations of Occupational Radiation Exposure During X-ray Guided Interventional Cardiology Procedures
(Master thesis, 2021-03-05)X-ray imaging is widely used as a diagnostic tool in many medical fields. Medical personnel can often reduce their exposure with distance and sufficient radiation protection, as they do not have to be close to the radiation ... -
