  1. 6. Self-supervised pre-training of an attention-based model for 3D medical image segmentation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Albert Sund Aillet; [2023]
    Keywords : Computer vision; Deep learning; 3D Medical image segmentation; Self-supervised learning; Datorseende; Djupinlärning; 3D Medicinsk bildsegmentering; Självövervakad träning;

    Abstract : Accurate segmentation of anatomical structures is crucial for radiation therapy in cancer treatment. Deep learning methods have been demonstrated effective for segmentation of 3D medical images, establishing the current standard. However, they require large amounts of labelled data and suffer from reduced performance on domain shift. READ MORE

  3. 7. Visualizing osteonecrosis of jaws through neutrophil elastase : [11C]NES novel PET tracer

    University essay from Uppsala universitet/Institutionen för läkemedelskemi

    Author : Amanda Dannberg; Theodora Martinez; [2023]
    Keywords : [11C]NES; HNC; MRONJ; neutrophil granulocytes; ORN; osteonecrosis; PET CT; radiation therapy; [11C]NES; huvud- och halscancer; MRONJ; neutrofila granulocyter; ORN; osteonekros; PET CT; strålbehandling;

    Abstract : Radiation and medical drugs are used to fight head and neck cancer, but unfortunately in some cases these treatments cause development of other diseases and injuries. Osteoradionecrosis (ORN) and medical-related osteonecrosis of the jaw (MRONJ) are dreaded late complications in jaws from radiation therapy and medical drugs and cause great suffering to those affected.

  4. 8. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Johansson Vivika; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation.

  5. 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.

  6. 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
