  1. 1. Improving proton therapy planning with photon-counting spectral computed tomography

    Master-uppsats, KTH/Fysik

    Författare :Karin Larsson; [2023]
    Nyckelord :Proton therapy; Medical imaging; Computed Tomography; Protonterapi; Medicinsk avbildning; Datortomografi;

    Sammanfattning : Proton radiation therapy is an alternative to conventional photon radiation therapy, which accounts for the majority of radiation treatments today. The rationale for using protons in radiation therapy lies in their dose deposition properties; photons deposit a radiation dose inversely proportional to the energy, and therefore tissue depth, while protons exhibit a sharp Bragg peak when traversing matter.

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

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Filip Hörberger; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : 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.

  4. 3. Uncertainties in Proton Therapy and Their Impact on Treatment Precision : Looking at Mechanical and Beam Alignment Uncertainties

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Albin Karlsson; [2022]
    Nyckelord :Proton therapy; Machine quality assurance; Uncertainties; Robust optimization;

    Sammanfattning : With the growing use and complexity of proton therapy, the safety and accuracy of the machines becomes increasing important. This, to be able to deliver the prescribed dose to the target while minimizing the dose to healthy tissue. LÄS MER

  5. 4. Proton Arc Therapy Optimization

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Cecilia Battinelli; [2019]
    Nyckelord :;

    Sammanfattning : Cancer is ranked among the leading causes of death in the world. During the last decades, the development of advanced cancer treatment software has had an increasingly important role in its treatment. To treat cancer, there are many different therapies, one of which is radiation therapy. LÄS MER
