    • Efficient Globally Optimal Matching of Anatomical Trees of the Liver 

      Laura, Cristina Oyarzun; Drechsler, Klaus (The Eurographics Association, 2010)
      Many inexact automatic tree matching algorithms are nowadays available. However, they provide matches that are not completely error free. Another option is to use manually matched node-pairs, but this enormously slows down ...

      bundles in the embedding tissue structures. White matter fiber tractography from diffusion tensor imaging (DTI) is, in general, visualized as 3D lines or tubes together with 2D anatomical MR slices or surfaces. However, ...
    • Graph Averaging as a Means to Compare Multichannel EEG Coherence Networks 

      Crippa, Alessandro; Maurits, Natasha M.; Roerdink, Jos B. T. M. (The Eurographics Association, 2010)
      A method is proposed for quantifying differences between multichannel EEG coherence networks represented by functional unit (FU) maps. The approach is based on inexact graph matching for attributed relational graphs and ...
    • Adapted Surface Visualization of Cerebral Aneurysms with Embedded Blood Flow Information 

      Gasteiger, Rocco; Neugebauer, Mathias; Kubisch, Christoph; Preim, Bernhard (The Eurographics Association, 2010)
      Cerebral aneurysms are a vascular dilatation induced by a pathological change of the vessel wall and often require treatment to avoid rupture. Therefore, it is of main interest, to estimate the risk of rupture, to gain a ...
