DOI: 10.1002/mp.12191
Abstract: Purpose While positron emission tomography (PET) allows for the imaging of tissues activated by proton beams in terms of monitoring the therapy administered, most endogenous tissue elements are activated by relatively high‐energy protons. Therefore, a… read more here.

DOI: 10.1016/j.ejmp.2018.06.123
Abstract: Purpose Proton therapy is widely used in state-of-the-art radiotherapy. However, precision of proton therapy could be affected by proton range uncertainties due to e.g. anatomy change, patient setting uncertainties. Prompt gamma (PG) imaging is investigated… read more here.

DOI: 10.1016/j.ejmp.2018.06.553
Abstract: Purpose Metal implants lead to streak and cupping artifacts in computed tomography (CT) images, causing erroneous CT number estimates for radiation therapy (RT) planning. We recently introduced kerMAR, a novel Magnetic Resonance (MR)-based CT metal… read more here.

DOI: 10.1080/0284186x.2022.2069477
Abstract: Accurate determination of the stopping power ratio (SPR) of the tissues along the beam path is required for calculations of dose deposition in proton therapy. Schneider et al. [1] proposed a stoichiometric calibration method to… read more here.

DOI: 10.1088/1361-6560/aa86e9
Abstract: Proton range random and systematic uncertainties are the major factors undermining the advantages of proton therapy, namely, a sharp dose falloff and a better dose conformality for lower doses in normal tissues. The influence of… read more here.

DOI: 10.1088/1361-6560/ab7506
Abstract: Technologies enabling in vivo range verification during proton therapy are actively sought as a means to reduce the clinical safety margins currently adopted to avoid tumor underdosage. In this contribution, we applied the semi-empirical theory… read more here.
