  • Multi-Contrast MRI Reconstruction with Structure-Guided Total Variation 

    Ehrhardt, Matthias Joachim; Betcke, Marta M (Society for Industrial and Applied MathematicsSIAM Journal on Imaging Sciences, 2016-08-04)
    Magnetic resonance imaging (MRI) is a versatile imaging technique that allows different contrasts depending on the acquisition parameters. Many clinical imaging studies acquire MRI data for more than one of these contrasts—such ...

  • PET Reconstruction with an Anatomical MRI Prior using Parallel Level Sets 

    Ehrhardt, Matthias Joachim; Markiewicz, Pawel; Liljeroth, Maria; Barnes, Anna; Kolehmainen, Ville; Duncan, John S; Pizarro, Luis; Atkinson, David; Hutton, Brian F; Ourselin, Sebastien; Thielemans, Kris; Arridge, Simon R (IEEEIEEE Transactions on Medical Imaging, 2016-04-14)
    The combination of positron emission tomography (PET) and magnetic resonance imaging (MRI) offers unique possibilities. In this paper we aim to exploit the high spatial resolution of MRI to enhance the reconstruction of ...
