A Survey of Cardiac 4D PC-MRI Data Processing
(The Eurographics Association, 2015)
Cardiac 4D PC-MRI acquisitions gained increasing clinical interest in recent years. They allow to non-invasively obtain extensive information about patient-specific hemodynamics and thus have a great potential to improve ...
Illustrative Multi-volume Rendering for PET/CT Scans
(The Eurographics Association, 2015)
In this paper we present illustrative visualization techniques for PET/CT datasets. PET/CT scanners acquire both PET and CT image data in order to combine functional metabolic information with structural anatomical ...
Histology-Based Evaluation of Optical Coherence Tomographic Characteristics of the Cerebral Artery Wall via Virtual Inflating
(The Eurographics Association, 2015)
With an increased rate of cerebrovascular diseases, the need for an advanced vessel wall analysis increases as well. In this work, we provide new information of cerebral artery walls extracted with optical coherence ...
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 ...
A Critical Analysis of the Evaluation Practice in Medical Visualization
(The Eurographics Association, 2018)
Medical visualization aims at directly supporting physicians in diagnosis and treatment planning, students and residents in medical education, and medical physicists as well as other medical researchers in answering specific ...
A Framework for Visual Comparison of 4D PC-MRI Aortic Blood Flow Data
(The Eurographics Association, 2018)
Four-dimensional phase-contrast magnetic resonance imaging (4D PC-MRI) allows for the non-invasive acquisition of in-vivo blood flow, producing a patient-specific blood flow model in selected vascular structures, e.g. the ...
Semi-Automatic Vessel Boundary Detection in Cardiac 4D PC-MRI Data Using FTLE fields
(The Eurographics Association, 2016)
Four-dimensional phase-contrast magnetic resonance imaging (4D PC-MRI) is a method to non-invasively acquire in-vivo blood flow, e.g. in the aorta. It produces three-dimensional, time-resolved datasets containing both flow ...
Automatic Generation of Web-Based User Studies to Evaluate Depth Perception in Vascular Surface Visualizations
(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 ...
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 ...
