Sequence- and Analysis Optimization for Partial Volume Correction in Arterial Spin Labelling based Perfusion MRI.
Digernes, Ingrid (Master thesis, 2014)Arterial spin labelling (ASL) is a magnetic resonance imaging (MRI) based method that can measure quantitatively cerebral blood flow (CBF) by magnetically labelling the arterial blood that perfuse the brain tissue. The ... -
Simulation of water self-diffusion in breast tissue
Bakken, Brynjar Larssen (Master thesis, 2018)Diffusion weighted magnetic resonance imaging (DW-MRI) can be used to distinguish malignant tumour tissue from benign lesions and healthy tissue. Although this is a well established clinical method, the detailed relationship ... -
Stereotactic Radiation Treatment of Lung Cancer by VMAT.
Hundvin, Johanna Austrheim (Master thesis, 2015)Radiotherapy of early stage non-small cell lung cancer (NSCLC) is a challenging treatment due to the varying tissue densities in the irradiated volume and the moving target. At Haukeland University Hospital (HUH) the ... -
