  • Generating a synthetic diffusion tensor dataset 

    Bergmann, Ørjan; Lundervold, Arvid; Steihaug, Trond (IEEE, 2005)
    During the last years, many techniques for de-noising, segmentation and fiber-tracking have been applied to diffusion tensor MR image data (DTI) from human and animal brains. However, evaluating such methods may be difficult ...
  • Global Minimization for Continuous Multiphase Partitioning Problems Using a Dual Approach 

    Bae, Egil; Yuan, Jing; Tai, Xue-Cheng (Springer Verlag, 2010)
    This paper is devoted to the optimization problem of continuous multi-partitioning, or multi-labeling, which is based on a convex relaxation of the continuous Potts model. In contrast to previous efforts, which are ...
  • Segmentation-Driven Image Registration-Application to 4D DCE-MRI Recordings of the Moving Kidneys 

    Hodneland, Erlend; Hanson, Erik Andreas; Lundervold, Arvid; Modersitzki, Jan; Eikefjord, Eli Bjøvad; Zanna, Antonella (IEEE, 2014-04-01)
    Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) of the kidneys requires proper motion correction and segmentation to enable an estimation of glomerular filtration rate through pharmacokinetic modeling. ...
