  1. 1. Development of a new SBRT dose planning strategy for thoracic tumours in RayStation

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Radiofysik

    Författare :Olof Westman; [2023]
    Nyckelord :radiotherapy sbrt lung robust; radioterapi;

    Sammanfattning : Umeå University Hospital has acquired a new treatment planning system, RayStation, for radiotherapy. It has a different set of dose calculation algorithms that require new planning strategies for stereotactic lung cancer treatments. LÄS MER

  3. 2. 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

  4. 3. Feasibility of adaptive SBRT of prostate cancer: Investigating uncertainties in AI-driven and CBCT-guided online adaptive radiotherapy

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Sevgi Emin; [2020]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose: Recent developments in external radiotherapy and its utilization with artificial in- telligence (AI) enables advanced treatment plans for a range of different disease sites. By adapting to the anatomy of the day, target coverage can be ensured while sparing more healthy tissue. LÄS MER

  5. 4. Characterization of Radiomics Features Extracted from Images Generated by the 0.35 T Scanner of an Integrated MRI-Linac

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Rebecka Ericsson Szecsenyi; [2020]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose: In an era of personalized oncology where the aim is to give every patient the right treatment at the right time an area of promising research is emerging called radiomics, or quantitative image analysis. The main underlying hypothesis is that pathophysiological information can be found in image texture not visible to the bare eye that can improve diagnosis, treatment adaption or be linked to a certain clinical outcome.

  7. 5. Robustness of the voluntary breath-hold approach for the treatment of early stage lung cancer with spot scanned proton therapy

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Jenny Dueck; [2013]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background: Intra- and interfractional variations in anatomy can cause unplanned substantial alterations of the dose distribution of the target in proton therapy. Motion management methods might be used in order to minimize anatomical variations. LÄS MER
