    • Amyloid Analyzer - A software assistant for qualitative and quantitative analysis of Florbetaben PET scans 

      Weiler, F.; Dicken, V.; Strehlow, J.; Geisler, B.; Scarpa, M.; Pessel, M.; Stephens, A.; Hahn, H. K. (The Eurographics Association, 2013)
      Amyloid imaging is currently on the verge of becoming a vital imaging biomarker for the diagnosis and progressmonitoring of Alzheimer's disease. It is a positron emission tomography (PET) imaging technique based on tracers ...

    • Combined Volume Registration and Visualization 

      Capps, Arlie G.; Zawadzki, Robert J.; Werner, John S.; Hamann, Bernd (The Eurographics Association, 2013)
      We describe a method for combining and visualizing a set of overlapping volume images with high resolution but limited spatial extent. Our system combines the calculation of a registration metric with ray casting for direct ...

    • Corrected Uncertainty in Probabilistic Segmentation Using Local Statistics 

      Ristovski, Gordan; Hahn, Horst; Linsen, Lars (The Eurographics Association, 2013)
      Probabilistic segmentation algorithms compute for each voxel and each segment of a medical imaging data set a probability that the voxel belongs to the segment. These per-voxel probability vectors are commonly used to ...

    • Functional Connectivity Glyphs for Brain Visualization 

      Böttger, J.; Schurade, R.; Margulies, D. S. (The Eurographics Association, 2013)
      The correlation of spontaneous brain activity, termed: functional connectivity, has become a valuable method in recent years for mapping brain organization. We present a novel approach to visualize functional connectivity ...

    • Hierarchical Poisson-Disk Sampling for Fiber Stipples 

      Hlawitschka, Mario; Goldau, Mathias; Wiebel, Alexander; Heine, Christian; Scheuermann, Gerik (The Eurographics Association, 2013)
      To understand neural tracts of the brain, neuroscientists use visualizations of diffusion data. Fiber stippling - a technique inspired by illustrations - accommodates probabilistic tracts, main diffusion direction, and ...

    • Improving Electrical Impedance Tomography Imaging of the Lung with Patient-specific 3D Models 

      Salz, P.; Reske, A.; Wrigge, H.; Scheuermann, G.; Hagen, H. (The Eurographics Association, 2013)
      Electrical Impedance Tomography (EIT) visualizes conductivity changes inside the thorax, which correlate with breathing and cardiac activity. While featuring high temporal resolution, no patient risks and bedside application, ...

    • Interactive Visualization of Neuroanatomical Data for a Hands-On Multimedia Exhibit 

      Rieder, C.; Brachmann, C.; Hofmann, B.; Klein, J.; Köhn, A.; Ojdanic, D.; Schumann, C.; Weiler, F.; Hahn, H. K. (The Eurographics Association, 2013)
      Magnetic resonance imaging is a technique which is routinely used by neuroradiologists. Within the last decade, several techniques have been developed to visualize those MR images so that medical experts, and thus the ...

    • Supervised Kernel Principal Component Analysis for Visual Sample-based Analysis of Gene Expression Data 

      Long, Tran Van; Linsen, Lars (The Eurographics Association, 2013)
      DNA microarray technology has enabled researchers to simultaneously investigate thousands of genes over hundreds of samples. Automatic classification of such data faces the challenge of dealing with smaller number of samples ...

    • Towards a Structured Analysis of Quantitative Descriptors from Segmented Biological Image Data 

      Leitte, H.; Portl, J.; Röder, I. V.; Schröder, R. R.; Wacker, I. (The Eurographics Association, 2013)
      Topological and morphological descriptions of (sub-)cellular structures play a central role in the understanding of biological processes. Deriving such descriptions from image data, however, is a challenging task that has ...

    • Towards Automatic Extraction of the Myocardium in Temporal MRI Using Object-based Segmentation 

      Chitiboi, Teodora; Hennemuth, Anja; Linsen, Lars; Hahn, Horst (The Eurographics Association, 2013)
      Visualizing the deformation of the myocardium over an entire heart cycle is essential for the assessment of local defects in the heart muscle. For this purpose, an automatic segmentation of the myocardium is a key requirement, ...

    • Visualization for Understanding Uncertainty in the Simulation of Myocardial Ischemia 

      Rosen, Paul; Burton, Brett; Potter, Kristin; Johnson, Chris R. (The Eurographics Association, 2013)
      We have created the Myocardial Uncertainty Viewer (muView or µView) tool for exploring data stemming from the forward simulation of cardiac ischemia. The simulation uses a collection of conductivity values to understand ...
