  1. 1. Polymer gel dosimetry with MRI-readout for 3D dose verification - detector characteristics and clinical applications

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Thi Guldhill; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. READ MORE

  3. 2. Correlation between Surface and Tumour Motion in Lung Cancer - including Deep Learning Perspectives

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Caisa Kjellström; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose: The purpose of this master thesis was to retrospectively investigate correlation between surface and tumour motion in lung cancer patients, alongside deep learning applications of the results. Additional correlations such as age, tumour volume and anatomical placement of the tumour were also investigated. READ MORE

  4. 3. 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.

  5. 4. 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

  6. 5. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Sara Falk; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. READ MORE
