  4. 3. " Optimization of Margins and Plan Robustness for Proton Therapy of Hodgkin’s Lymphoma"

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Filip Hörberger; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose/Background: Utilizing proton therapy (PT) for treatment of Hodgkin’s lymphoma (HL) has demonstrated favorable features, particularly a reduced dose to organs at risk (OAR) in comparison with photon radiotherapy. However, there is a coherent complexity with PT including its uncertainties, such as range-uncertainties and set-up variations as protons are highly sensitive to tissue density variations within the beam-path.
