  3. 2. Limited angle reconstruction for 2D CT based on machine learning

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Eric Oldgren; Knut Salomonsson; [2023]
    Keywords : CT; computed tomography; limited angle; machine learning; limited data; ill posed problem; inverse problem;

    Abstract : The aim of this report is to study how machine learning can be used to reconstruct 2 dimensional computed tomography images from limited angle data. This could be used in a variety of applications where either the space or timeavailable for the CT scan limits the acquired data.In this study, three different types of models are considered.

  5. 4. Radiotherapy treatment strategy for prostate cancer with lymph node involvement

    University essay from Umeå universitet/Institutionen för fysik

    Author : Amanda Östensson; [2023]
    Keywords : Radiotherapy; prostate cancer; lymph node; gold fiducial marker; multiple target;

    Abstract : Radiotherapy is a common and useful method for treating prostate cancer, often using gold fiducial markers in the prostate as guidance. However, when there is a high risk of lymph node involvement, the independent motion of volumes causes complications in patient positioning since there is a choice between position against the gold fiducial markers or the bone anatomy.

  6. 5. Simulating metal ct artefacts for ground truth generation in deep learning.

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Arthur Barakat; [2023]
    Keywords : Technology and Engineering;

    Abstract : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.
