VOLUME DATA ANALYSIS
AND VISUALIZATION
Volume Analysis
• Identification of features in volumetric data, e.g.
seismic volumes, medical imaging data, etc. [1-5]
– Find regions in parameter space which correspond to
distinct spatial structures
delineating blood vessels in angiography
removing artifacts in industrial CT
Volume Exploration
• Finding of patterns in
large spatial data
collections [8-10]
– Interactive tools for visual
exploration, navigation,
and analysis
– Categorization of the
output space using spatial
similarity measures
– Applications: fluid
simulation, neurobiology,
medicine, etc.
Smart Interaction
• AngioVis: advanced visualization for improved diagnosis of
vascular decease [11-13]
– Next-generation radiology workstation, in daily clinical use at
the Vienna General Hospital
• LiveSync: synchronized interaction with 2D and 3D images
in medical workstations [14-17]
– Integrated into AFGA HealthCare software, several granted
patents
Illustrative Visualization
• Interactive presentation of complex 3D datasets
in an easily-understandable way based on
illustration techniques [18-25]
– GPU-based methods for generating cutaway views,
exploded views, stylized shading, etc.
– VolumeShop software framework: rapid-prototyping
toolkit for volume visualization & remote rendering
Real-Time Rendering
• Real-time realistic volume
visualization from live 4D ultrasound
data [26-28]
– High-quality rendering with at a fraction
of the cost of previous methods
– Research and technology transfer project
with GE Healthcare, available on Voluson
US scanners
