    • Efficient Globally Optimal Matching of Anatomical Trees of the Liver 

      Laura, Cristina Oyarzun; Drechsler, Klaus (The Eurographics Association, 2010)
      Many inexact automatic tree matching algorithms are nowadays available. However, they provide matches that are not completely error free. Another option is to use manually matched node-pairs, but this enormously slows down ...
    • Anatomical Volume Visualization with Weighted Distance Fields 

      Kerwin, Thomas; Hittle, Brad; Shen, Han-Wei; Stredney, Don; Wiet, Gregory (The Eurographics Association, 2010)
      We describe the use of the weighted distance transform (WDT) to enhance applications designed for volume visualization of segmented anatomical datasets. The WDT is presented as a general technique to generate a derived ...
    • Staircase-Aware Smoothing of Medical Surface Meshes 

      Moench, Tobias; Adler, Simon; Preim, Bernhard (The Eurographics Association, 2010)
      The evaluation of spatial relationships between anatomic structures is a major task in surgical planning. Surface models generated from medical image data (intensity, binary) are often used for visualization and 3D measurement ...
    • Interactive Real Time Simulation of Cardiac Radio-Frequency Ablation 

      Pernod, Erik; Sermesant, Maxime; Relan, Jatin; Delingette, Herve (The Eurographics Association, 2010)
      Virtual reality based therapy simulation meets a growing interest from the medical community due to its potential impact for the training of medical residents and the planning of therapies. In this paper, we describe a ...
    • Visual Analysis of Integrated Resting State Functional Brain Connectivity and Anatomy 

      Dixhoorn, Andre F. van; Vissers, Bastijn H.; Ferrarini, Luca; Milles, Julien; Botha, Charl P. (The Eurographics Association, 2010)
      Resting state functional magnetic resonance imaging (rs-fMRI) is an important modality in the study of the functional architecture of the human brain. The correlation between the resting state fMRI activity traces of ...
    • Importance-Driven Structure Categorization for 3D Surgery Planning 

      Baer, Alexandra; Kellermann, Kerstin; Preim, Bernhard (The Eurographics Association, 2010)
      We present an importance-driven categorization approach to automatically gather all currently required structures for the surgery planning process. Therefore, we analyzed common demands for tumor intervention planning and ...
    • Model-based Solid Texture Synthesis for Anatomic Volume Illustration 

      Kabul, Ilknur; Merck, Derek; Rosenman, Julian; Pizer, Stephen M. (The Eurographics Association, 2010)
      Medical illustrations can make powerful use of texture synthesis to convey information about anatomic structures in an attractive, effective and understandable way. Current visualization methods are not capable of conveying ...
    • A General Approach to Model Biomedical Data from 3D Unorganised Point Clouds with Medial Scaffolds 

      Leymarie, Frederic Fol; Chang, Ming-Ching; Imielinska, Celina; Kimia, Benjamin B. (The Eurographics Association, 2010)
      We present the latest developments in modeling 3D biomedical data via the Medial Scaffold (MS), a 3D acyclic oriented graph representation of the Medial Axis (MA) [LK07, SP08]. TheMS (and associated 3DMA) can be computed ...
    • Estimation of the Midsagittal Plane for Sideness Determination of Malignant Structures of Head and Neck 

      Rössling, Ivo; Hahn, Peter; Cyrus, Christian; Dornheim, Lars (The Eurographics Association, 2010)
      Besides other main criterias like size, infiltration and anatomical district, the sideness of tumor and local metastases (i. e., malignant lymph nodes) is very crucial for head and neck tumor assessment. An automatic ...
    • Guided Visualization of Ultrasound Image Sequences 

      Angelelli, Paolo; Viola, Ivan; Nylund, Kim; Gilja, Odd Helge; Hauser, Helwig (The Eurographics Association, 2010)
      Ultrasonography allows informative and expressive real time examinations of patients. Findings are usually reported as printouts, screen shots and video sequences. However, in certain scenarios, the amount of imaged ...
    • Visualizing White Matter Fiber Tracts with Optimally Fitted Curved Dissection Surfaces 

      Schurade, Ralph; Hlawitschka, Mario; Hamann, Bernd; Scheuermann, Gerik; Knösche, Thomas R.; Anwander, Alfred (The Eurographics Association, 2010)
      bundles in the embedding tissue structures. White matter fiber tractography from diffusion tensor imaging (DTI) is, in general, visualized as 3D lines or tubes together with 2D anatomical MR slices or surfaces. However, ...
    • Dynamic Visualisation of Orbital Fat Deformation using Anatomy-Guided Interaction 

      Schaafsma, Peter J.; Schutte, Sander; Simonsz, Huib J.; Post, Frits H.; Botha, Charl P. (The Eurographics Association, 2010)
      The human eye is a biomechanical system. Orbital fat plays an important role in the working of this system, but its behaviour during eye movement is not well understood. To give insight into this behaviour, visualisation ...
    • Accelerated Diffusion Operators for Enhancing DW-MRI 

      Rodrigues, Paulo; Duits, Remco; Romeny, Bart M. ter Haar; Vilanova, Anna (The Eurographics Association, 2010)
      the intra-voxel diffusion pattern compared to its simpler predecessor diffusion tensor imaging (DTI). However, HARDI in general produces very noisy diffusion patterns due to the low SNR from the scanners at high b-values. ...
    • Graph Averaging as a Means to Compare Multichannel EEG Coherence Networks 

      Crippa, Alessandro; Maurits, Natasha M.; Roerdink, Jos B. T. M. (The Eurographics Association, 2010)
      A method is proposed for quantifying differences between multichannel EEG coherence networks represented by functional unit (FU) maps. The approach is based on inexact graph matching for attributed relational graphs and ...
