    • 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 ...

    • COMFIS - Comparative Visualization of Simulated Medical Flow Data 

      Meuschke, Monique; Voß, Samuel; Eulzer, Pepe; Janiga, Gabor; Arens, Christoph; Wickenhöfer, Ralph; Preim, Bernhard; Lawonn, Kai (The Eurographics Association, 2022)
      Simulations of human blood and airflow are playing an increasing role in personalized medicine. Comparing flow data of different treatment scenarios or before and after an intervention is important to assess treatment ...

    • Communicating Pathologies and Growth to a General Audience 

      Mittenentzwei, Sarah; Mlitzke, Sophie; Lawonn, Kai; Preim, Bernhard; Meuschke, Monique (The Eurographics Association, 2023)
      In this paper, we investigate the suitability of different visual representations of pathological growth using surface models of intracranial aneurysms and liver tumors. By presenting complex medical information in a ...

    • 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 ...

    • Distance Visualizations for Vascular Structures in Desktop and VR: Overview and Implementation 

      Hombeck, Jan; Meuschke, Monique; Lieb, Simon; Lichtenberg, Nils; Datta, Rabi; Krone, Michael; Hansen, Christian; Preim, Bernhard; Lawonn, Kai (The Eurographics Association, 2022)
      The role of expressive surface visualizations in rendering vascular structures has seen an increased impact over the last years. Surface visualizations provide an overview of complex anatomical structures and support ...

    • Is there a Tornado in Alex's Blood Flow? A Case Study for Narrative Medical Visualization 

      Kleinau, Anna; Stupak, Evgenia; Mörth, Eric; Garrison, Laura A.; Mittenentzwei, Sarah; Smit, Noeska N.; Lawonn, Kai; Bruckner, Stefan; Gutberlet, Matthias; Preim, Bernhard; Meuschke, Monique (The Eurographics Association, 2022)
      Narrative visualization advantageously combines storytelling with new media formats and techniques, like interactivity, to create improved learning experiences. In medicine, it has the potential to improve patient understanding ...

    • 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 ...

    • Perceptual Evaluation of Common Line Variables for Displaying Uncertainty on Molecular Surfaces 

      Sterzik, Anna; Lichtenberg, Nils; Krone, Michael; Cunningham, Douglas W.; Lawonn, Kai (The Eurographics Association, 2022)
      Data are often subject to some degree of uncertainty, whether aleatory or epistemic. This applies both to experimental data acquired with sensors as well as to simulation data. Displaying these data and their uncertainty ...

    • 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 ...

    • Visualizing Carotid Stenoses for Stroke Treatment and Prevention 

      Eulzer, Pepe; Richter, Kevin; Hundertmark, Anna; Meuschke, Monique; Wickenhöfer, Ralph; Klingner, Carsten M.; Lawonn, Kai (The Eurographics Association, 2023)
      Analyzing carotid stenoses - potentially lethal constrictions of the brain-supplying arteries - is a critical task in clinical stroke treatment and prevention. Determining the ideal type of treatment and point for surgical ...
