    Visually Guided Mesh Smoothing for Medical Applications 

    Moench, Tobias; Kubisch, Christoph; Lawonn, Kai; Westermann, Ruediger; Preim, Bernhard (The Eurographics Association, 2012)
    Surface models derived from medical image data often exhibit artifacts, such as noise and staircases, which can be reduced by applying mesh smoothing filters. Usually, an iterative adaption of smoothing parameters to the ...

    Comparative Blood Flow Visualization for Cerebral Aneurysm Treatment Assessment 

    Pelt, Roy van; Gasteiger, Rocco; Lawonn, Kai; Meuschke, Monique; Preim, Bernhard (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    A pathological vessel dilation in the brain, termed cerebral aneurysm, bears a high risk of rupture, and is associated with a high mortality. In recent years, incidental findings of unruptured aneurysms have become more ...

    Semi-automatic Vortex Flow Classification in 4D PC-MRI Data of the Aorta 

    Meuschke, Monique; Köhler, Benjamin; Preim, Uta; Preim, Bernhard; Lawonn, Kai (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We present an Aortic Vortex Classification (AVOCLA) that allows to classify vortices in the human aorta semi-automatically. Current medical studies assume a strong relation between cardiovascular diseases and blood flow ...

    Streamlines for Illustrative Real-Time Rendering 

    Lawonn, Kai; Moench, Tobias; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Line drawing techniques are important methods to illustrate shapes. Existing feature line methods, e.g., suggestive contours, apparent ridges, or photic extremum lines, solely determine salient regions and illustrate them ...

    Illustrative Multi-volume Rendering for PET/CT Scans 

    Lawonn, Kai; Smit, Noeska; Preim, Bernhard; Vilanova, Anna (The Eurographics Association, 2015)
    In this paper we present illustrative visualization techniques for PET/CT datasets. PET/CT scanners acquire both PET and CT image data in order to combine functional metabolic information with structural anatomical ...

    AmniVis - A System for Qualitative Exploration of Near-Wall Hemodynamics in Cerebral Aneurysms 

    Neugebauer, Mathias; Lawonn, Kai; Beuing, Oliver; Berg, Philipp; Janiga, Gabor; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    The qualitative exploration of near-wall hemodynamics in cerebral aneurysms provides important insights for risk assessment. For instance, a direct relation between complex flow patterns and aneurysm formation could be ...

    Line Integral Convolution for Real-Time Illustration of Molecular Surface Shape and Salient Regions 

    Lawonn, Kai; Krone, Michael; Ertl, Thomas; Preim, Bernhard (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a novel line drawing algorithm that illustrates surfaces in real-time to convey their shape. We use line integral convolution (LIC) and employ ambient occlusion for illustrative surface rendering. Furthermore, ...

    Automatic Generation of Web-Based User Studies to Evaluate Depth Perception in Vascular Surface Visualizations 

    Meuschke, Monique; Smit, Noeska N.; Lichtenberg, Nils; Preim, Bernhard; Lawonn, Kai (The Eurographics Association, 2018)
    User studies are often required in biomedical visualization application papers in order to provide evidence for the utility of the presented approach. An important aspect is how well depth information can be perceived, as ...

    Aneulysis - A System for Aneurysm Data Analysis 

    Meuschke, Monique; Wickenhöfer, Ralph; Preim, Bernhard; Lawonn, Kai (The Eurographics Association, 2020)
    We present ANEULYSIS, a system to improve risk assessment and treatment planning of cerebral aneurysms. Aneurysm treatment must be carefully examined as there is a risk of fatal outcome during surgery. Aneurysm growth, ...
