    • Automatic Animations to Analyze Blood Flow Data 

      Apilla, Vikram; Behrendt, Benjamin; Lawonn, Kai; Preim, Bernhard; Meuschke, Monique (The Eurographics Association, 2021)
      We present an approach for computing camera animations composed of optimal views to support the visual exploration of blood flow data using cerebral aneurysms as major example. Medical researchers are interested in hemodynamic ...

    • Automatic Cutting and Flattening of Carotid Artery Geometries 

      Eulzer, Pepe; Richter, Kevin; Meuschke, Monique; Hundertmark, Anna; Lawonn, Kai; , (The Eurographics Association, 2021)
      We propose a novel method to cut and flatten vascular geometry that results in an intuitive mapping between the 3D and 2D domains. Our approach is fully automatic, and the sole input is the vessel geometry. We aim to ...

    • Clasping Trees - A Pipeline for Interactive Procedural Tree Generation 

      Lieb, Simon J.; Klee, Nicolas; Lawonn, Kai (The Eurographics Association, 2022)
      Trees in computer games are important components of an immersive game world. Realistic trees adapt to the environment in terms of shape and growth. Manually adapting each tree to its immediate environment is time-consuming. ...

    • A Fully Integrated Pipeline for Visual Carotid Morphology Analysis 

      Eulzer, Pepe; Deylen, Fabienne von; Hsu, Wei-Chan; Wickenhöfer, Ralph; Klingner, Carsten M.; Lawonn, Kai (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      Analyzing stenoses of the internal carotids - local constrictions of the artery - is a critical clinical task in cardiovascular disease treatment and prevention. For this purpose, we propose a self-contained pipeline for ...

    • InkVis: A High-Particle-Count Approach for Visualization of Phase-Contrast Magnetic Resonance Imaging Data 

      de Hoon, Niels; Lawonn, Kai; Jalba, Andrei; Eisemann, Elmar; Vilanova, Anna (The Eurographics Association, 2019)
      Phase-Contrast Magnetic Resonance Imaging (PC-MRI) measures volumetric and time-varying blood flow data, unsurpassed in quality and completeness. Such blood-flow data have been shown to have the potential to improve both ...

    • Interactive Multimodal Imaging Visualization for Multiple Sclerosis Lesion Analysis 

      Sugathan, Sherin; Bartsch, Hauke; Riemer, Frank; Grüner, Renate; Lawonn, Kai; Smit, Noeska N. (The Eurographics Association, 2021)
      Multiple Sclerosis (MS) is a brain disease that is diagnosed and monitored extensively through MRI scans. One of the criteria is the appearance of so-called brain lesions. The lesions show up on MRI scans as regions with ...

    • An Overview of Techniques for Egocentric Black Hole Visualization and Their Suitability for Planetarium Applications 

      Hissbach, Anny-Marleen; Dick, Christian; Lawonn, Kai (The Eurographics Association, 2022)
      The visualization of black holes is used in science communication to educate people about our universe and concepts of general relativity. Recent visualizations aim to depict black holes in realtime, overcoming the challenge ...

    • A Survey of Visual Analytics for Public Health 

      Preim, Bernhard; Lawonn, Kai (© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)
      We describe visual analytics solutions aiming to support public health professionals, and thus, preventive measures. Prevention aims at advocating behaviour and policy changes likely to improve human health. Public health ...

    • Vessel Maps: A Survey of Map-Like Visualizations of the Cardiovascular System 

      Eulzer, Pepe; Meuschke, Monique; Mistelbauer, Gabriel; Lawonn, Kai (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Map-like visualizations of patient-specific cardiovascular structures have been applied in numerous medical application contexts. The term map-like alludes to the characteristics these depictions share with cartographic ...
