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

    University essay from KTH/Fysik

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

    Abstract : 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.

  2. 7. Increasing the Efficiency of CyberKnife Cancer Treatments by Faster Robot Traversal Paths

    University essay from KTH/Matematisk statistik

    Author : Theodor Hagström; [2023]
    Keywords : Bachelor thesis; Radiation therapy; CyberKnife; Applied mathematics; Optimization; Treatment time; Traversal Time; Kandidatexamensarbete; Strålbehandling; CyberKnife; Tillämpad matematik; Optimering; Behandlingstid; Rörelsetid;

    Abstract : Cancer remains a significant global challenge, constituting one of the leading causes of death worldwide. With an aging population, the demand for cancer treatments is increasing. Nevertheless, due to technological advancements, cancer mortality rates are declining. READ MORE

  3. 8. STANDARDIZED ORGAN AT RISK VOLUME FOR EXTERNAL BEAM RADIATION THERAPY IN PROSTATE CANCER AND ITS RELATIONSHIP TO VOLUMES DEFINED BY CLINICAL PRACTICE

    University essay from

    Author : Dang Thao; [2022-01-13]
    Keywords : Medical physics; Radiation therapy; Prostate cancer; Organs at risk;

    Abstract : Background/ Purpose: In radiation therapy (RT), the radiation dose calculated in tumours and normal tissue depends on how the volumes are defined. It is difficult to standardize how tumour volumes should be defined because their anatomical extension can differ greatly between individuals. READ MORE

  4. 9. " 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.

  5. 10. Evaluation of the treatment planning system decimal ElectronRT and custom-made bolus for FLASH-irradiation

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Mizgin Coskun; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: The novel external beam therapy technique using ultra-high dose rates known as FLASH has become known for its normal tissue sparing effect. Currently in Lund, veterinary clinical trials are carried out on canine patients using electrons with ultra- high dose rates. READ MORE
