Anatomy-Guided Multi-Level Exploration of Blood Flow in Cerebral Aneurysms
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
For cerebral aneurysms, the ostium, the area of inflow, is an important anatomic landmark, since it separates the pathological vessel deformation from the healthy parent vessel. A better understanding of the inflow ...
Perceptual Evaluation of Ghosted View Techniques for the Exploration of Vascular Structures and Embedded Flow
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
This paper presents three controlled perceptual studies investigating the visualization of the cerebral aneurysm anatomy with embedded flow visualization. We evaluate and compare the common semitransparent visualization ...
Streamlines for Illustrative Real-Time Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Line drawing techniques are important methods to illustrate shapes. Existing feature line methods, e.g., suggestive contours, apparent ridges, or photic extremum lines, solely determine salient regions and illustrate them ...
Comparative Blood Flow Visualization for Cerebral Aneurysm Treatment Assessment
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
A pathological vessel dilation in the brain, termed cerebral aneurysm, bears a high risk of rupture, and is associated with a high mortality. In recent years, incidental findings of unruptured aneurysms have become more ...
Reusable Visualizations and Animations for Surgery Planning
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
For surgical planning, the exploration of 3D visualizations and 2D slice views is essential. However, the generation of visualizations which support the specific treatment decisions is very tedious. Therefore, the reuse ...
Reliable Adaptive Modelling of Vascular Structures with Non-Circular Cross-Sections
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Accurate visualizations of complex vascular structures are essential for medical applications, such as diagnosis, therapy planning and medical education. Vascular trees are usually described using centerlines, since they ...
AmniVis - A System for Qualitative Exploration of Near-Wall Hemodynamics in Cerebral Aneurysms
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
The qualitative exploration of near-wall hemodynamics in cerebral aneurysms provides important insights for risk assessment. For instance, a direct relation between complex flow patterns and aneurysm formation could be ...
Line Integral Convolution for Real-Time Illustration of Molecular Surface Shape and Salient Regions
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present a novel line drawing algorithm that illustrates surfaces in real-time to convey their shape. We use line integral convolution (LIC) and employ ambient occlusion for illustrative surface rendering. Furthermore, ...
Semi-automatic Vortex Flow Classification in 4D PC-MRI Data of the Aorta
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present an Aortic Vortex Classification (AVOCLA) that allows to classify vortices in the human aorta semi-automatically. Current medical studies assume a strong relation between cardiovascular diseases and blood flow ...
