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

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Caisa Kjellström; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : 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. LÄS MER

  3. 2. 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.

  4. 3. Hjälpmedel för laryngektomiopererade

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ines Lindstedt Hidiri; Ludvig Risbecker; [2023]
    Nyckelord :;

    Sammanfattning : Vid insjuknande i allvarlig cancer i struphuvudet kan struphuvudet behöva elimineras för att säkra en frisk framtid. Cancer i struphuvudet kommer till stor del från rökning och alkoholkonsumtion. I Sverige är genomsnittsåldern 69 år och 80% av patienterna är män. Det uppkommer drygt 175 nya fall per år i Sverige.

  5. 4. " 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.

  7. 5. Simulation of Microwave Heating of Healthy and Cancerous Human Tissue With Gold Nanoparticles

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hampus Carlens; Mika Söderström; [2022]
    Nyckelord :Gold nanoparticle GNP ; Electrophoretic resonance; Dispersive permittivity; Cancer treatment; Waveguide; Radiotherapy; Graded material.;

    Sammanfattning : With a great need for new and better cancer treatments, microwaves and gold nanoparticles (GNPs) are increasingly being suggested to be used in radiotherapy. In thisreport, the authors present an investigation of how human tissue,both malignant and healthy, behaves under microwave radiation. LÄS MER
