  1. 11. Dose painting : Can radiotherapy be improved with image driven dose-responses derived from retrospective radiotherapy data?

    Författare :Eric Grönlund; Anders Ahnesjö; Silvia Johansson; Daniela Thorwarth; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; functional imaging; dose painting; dose painting by numbers; robust optimization; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : The main aim of curative radiotherapy for cancer is to prescribe and deliver doses that eradicate the tumor and spare the normal healthy tissues. Radiotherapy is commonly performed by delivering a homogeneous radiation dose to the tumor. LÄS MER

  4. 13. Optimization of radiotherapy in locally advanced lung cancer

    Författare :Andreas Hallqvist; Göteborgs universitet; []
    Nyckelord :radiotherapy; lung cancer;

    Sammanfattning : Lung cancer is the leading cause of cancer death worldwide as well as in Sweden, where the incidence is around 3500 new cases per year. About 50% have distant metastases by the time of diagnosis and are treated with palliative intent. LÄS MER

  5. 14. Patient Positioning in Radiotherapy Using Body Surface Scanning

    Författare :Kenneth Wikström; Anders Ahnesjö; Sven Bäck; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; positioning; body surface; laser scanning; cancer; SGRT; ITV; lung cancer; surrogate; tumour motion; 4DCT; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : External radiotherapy uses ionising radiation to damage the DNA of the tumour cells and thereby inhibit their uncontrolled proliferation. The technical development regarding imaging and visualisation for radiotherapy has increased considerably during the last decades. LÄS MER

  7. 15. Contributions to deep learning for imaging in radiotherapy

    Författare :Attila Simkó; Joakim Jonsson; Tommy Löfstedt; Anders Garpebring; Tufve Nyholm; Veronika Cheplygina; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; deep learning; medical imaging; radiotherapy; artefact correction; bias field correction; contrast transfer; synthetic CT; reproducibility;

    Sammanfattning : Purpose: The increasing importance of medical imaging in cancer treatment, combined with the growing popularity of deep learning gave relevance to the presented contributions to deep learning solutions with applications in medical imaging.Relevance: The projects aim to improve the efficiency of MRI for automated tasks related to radiotherapy, building on recent advancements in the field of deep learning.
