Fiber Stipples for Crossing Tracts in Probabilistic Tractography
(The Eurographics Association, 2015)
Given diffusion weighted magnetic resonance (dMRI) data, tractography methods may reconstruct estimations of neural connections of the human brain, so called tractograms. Probabilistic tractography algorithms generate a ...
Graxels: Information Rich Primitives for the Visualization of Time-Dependent Spatial Data
(The Eurographics Association, 2016)
Time-dependent volumetric data has important applications in areas as diverse as medicine, climatology, and engineering. However, the simultaneous quantitative assessment of spatial and temporal features is very challenging. ...
How to Evaluate Medical Visualizations on the Example of 3D Aneurysm Surfaces
(The Eurographics Association, 2016)
For the evaluation of medical visualizations, a ground truth is often missing. Therefore, the evaluation of medical visualizations is often restricted to qualitative comparisons w.r.t user preferences but neglects more ...
Monte-Carlo Ray-Tracing for Realistic Interactive Ultrasound Simulation
(The Eurographics Association, 2016)
Ray-based simulations have been shown to generate impressively realistic ultrasound images in interactive frame rates. Recent efforts used GPU-based surface ray-tracing to simulate complex ultrasound interactions such as ...
Illustrative Transitions in Molecular Visualization via Forward and Inverse Abstraction Transform
(The Eurographics Association, 2016)
A challenging problem in biology is the incompleteness of acquired information when visualizing biological phenomena. Structural biology generates detailed models of viruses or bacteria at different development stages, ...
Aortic Dissection Maps: Comprehensive Visualization of Aortic Dissections for Risk Assessment
(The Eurographics Association, 2016)
Aortic dissection is a life threatening condition of the aorta, characterized by separation of its wall layers into a true and false lumen. A subset of patients require immediate surgical or endovascular repair. All survivors ...
BrainCove: A Tool for Voxel-wise fMRI Brain Connectivity Visualization
(The Eurographics Association, 2012)
Functional brain connectivity from fMRI studies has become an important tool in studying functional interactions in the human brain as a complex network. Most recently, research has started focusing on whole brain functional ...
A Framework for Fast Initial Exploration of PC-MRI Cardiac Flow
(The Eurographics Association, 2016)
Cardiac flow is still not fully understood, and is currently an active research topic. Using phase-contrast magnetic resonance imaging (PC-MRI) blood flow can be measured. For the inspection of such flow, researchers often ...
Sline: Seamless Line Illustration for Interactive Biomedical Visualization
(The Eurographics Association, 2016)
In medical visualization of surface information, problems often arise when visualizing several overlapping structures simultaneously. There is a trade-off between visualizing multiple structures in a detailed way and ...
Unfolding and Interactive Exploration of Protein Tunnels and their Dynamics
(The Eurographics Association, 2016)
The presence of tunnels in protein structures substantially influences their reactivity with other molecules. Therefore, studying their properties and changes over time has been in the scope of biochemists for decades. In ...
