    • 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, ...
    • 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 ...
    • Autonomous Particles for Interactive Flow Visualization 

      Engelke, Wito; Lawonn, Kai; Preim, Bernhard; Hotz, Ingrid (© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We present an interactive approach to analyse flow fields using a new type of particle system, which is composed of autonomous particles exploring the flow. While particles provide a very intuitive way to visualize flows, ...
    • Distance Field Visualization and 2D Abstraction of Vessel Tree Structures with on-the-fly Parameterization 

      Lichtenberg, Nils; Krayer, Bastian; Hansen, Christian; Müller, Stefan; Lawonn, Kai (The Eurographics Association, 2019)
      In this paper, we make contributions to the visualization of vascular structures. Based on skeletal input data, we provide a combined 2D and implicit 3D visualization of vasculature, that is parameterized on-the-fly for ...
    • EuroRV3 2017: Frontmatter 

      Lawonn, Kai; Smit, Noeska; Cunningham, Douglas (Eurographics Association, 2017)
    • A Geometric Optimization Approach for the Detection and Segmentation of Multiple Aneurysms 

      Lawonn, Kai; Meuschke, Monique; Wickenhöfer, Ralph; Preim, Bernhard; Hildebrandt, Klaus (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We present a method for detecting and segmenting aneurysms in blood vessels that facilitates the assessment of risks associated with the aneurysms. The detection and analysis of aneurysms is important for medical diagnosis ...
    • Model-based Visualization for Medical Education and Training 

      Smit, Noeska; Lawonn, Kai; Kraima, Annelot; deRuiter, Marco; Bruckner, Stefan; Eisemann, Elmar; Vilanova, Anna (The Eurographics Association, 2019)
      Anatomy, or the study of the structure of the human body, is an essential component of medical education. Certain parts of human anatomy are considered to be more complex to understand than others, due to a multitude of ...
    • Parameterization and Feature Extraction for the Visualization of Tree-like Structures 

      Lichtenberg, Nils; Lawonn, Kai (The Eurographics Association, 2018)
      The study and visualization of vascular structures, using 3D models obtained from medical data, is an active field of research. Illustrative visualizations have been applied to this domain in multiple ways. Researchers ...
    • Robustness Evaluation of CFD Simulations to Mesh Deformation 

      Scheid-Rehder, Alexander; Lawonn, Kai; Meuschke, Monique (The Eurographics Association, 2019)
      CFD simulations are an increasingly important method for the non-invasive analysis of risk factors for aneurysm rupture. Their robustness, however, has to be examined more thoroughly before clinical use is possible. We ...
    • Stylized Image Triangulation 

      Lawonn, Kai; Günther, Tobias (© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
      The art of representing images with triangles is known as image triangulation, which purposefully uses abstraction and simplification to guide the viewer's attention. The manual creation of image triangulations is tedious ...
    • A Survey of Surface‐Based Illustrative Rendering for Visualization 

      Lawonn, Kai; Viola, Ivan; Preim, Bernhard; Isenberg, Tobias (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      In this paper, we survey illustrative rendering techniques for 3D surface models. We first discuss the field of illustrative visualization in general and provide a new definition for this sub‐area of visualization. For the ...
    • TrustVis 2019: Frontmatter 

      Kosara, Robert; Lawonn, Kai; Linsen, Lars; Smit, Noeska (The Eurographics Association, 2019)
