Towards a Structured Analysis of Quantitative Descriptors from Segmented Biological Image Data
(The Eurographics Association, 2013)Topological and morphological descriptions of (sub-)cellular structures play a central role in the understanding of biological processes. Deriving such descriptions from image data, however, is a challenging task that has ... -
Combined Volume Registration and Visualization
(The Eurographics Association, 2013)We describe a method for combining and visualizing a set of overlapping volume images with high resolution but limited spatial extent. Our system combines the calculation of a registration metric with ray casting for direct ... -
Interactive Visualization of Neuroanatomical Data for a Hands-On Multimedia Exhibit
(The Eurographics Association, 2013)Magnetic resonance imaging is a technique which is routinely used by neuroradiologists. Within the last decade, several techniques have been developed to visualize those MR images so that medical experts, and thus the ... -
Visualization for Understanding Uncertainty in the Simulation of Myocardial Ischemia
(The Eurographics Association, 2013)We have created the Myocardial Uncertainty Viewer (muView or µView) tool for exploring data stemming from the forward simulation of cardiac ischemia. The simulation uses a collection of conductivity values to understand ... -
Supervised Kernel Principal Component Analysis for Visual Sample-based Analysis of Gene Expression Data
(The Eurographics Association, 2013)DNA microarray technology has enabled researchers to simultaneously investigate thousands of genes over hundreds of samples. Automatic classification of such data faces the challenge of dealing with smaller number of samples ... -
Towards Automatic Extraction of the Myocardium in Temporal MRI Using Object-based Segmentation
(The Eurographics Association, 2013)Visualizing the deformation of the myocardium over an entire heart cycle is essential for the assessment of local defects in the heart muscle. For this purpose, an automatic segmentation of the myocardium is a key requirement, ... -
Improving Electrical Impedance Tomography Imaging of the Lung with Patient-specific 3D Models
(The Eurographics Association, 2013)Electrical Impedance Tomography (EIT) visualizes conductivity changes inside the thorax, which correlate with breathing and cardiac activity. While featuring high temporal resolution, no patient risks and bedside application, ... -
Amyloid Analyzer - A software assistant for qualitative and quantitative analysis of Florbetaben PET scans
(The Eurographics Association, 2013)Amyloid imaging is currently on the verge of becoming a vital imaging biomarker for the diagnosis and progressmonitoring of Alzheimer's disease. It is a positron emission tomography (PET) imaging technique based on tracers ... -
Hierarchical Poisson-Disk Sampling for Fiber Stipples
(The Eurographics Association, 2013)To understand neural tracts of the brain, neuroscientists use visualizations of diffusion data. Fiber stippling - a technique inspired by illustrations - accommodates probabilistic tracts, main diffusion direction, and ... -
Corrected Uncertainty in Probabilistic Segmentation Using Local Statistics
(The Eurographics Association, 2013)Probabilistic segmentation algorithms compute for each voxel and each segment of a medical imaging data set a probability that the voxel belongs to the segment. These per-voxel probability vectors are commonly used to ... -
Functional Connectivity Glyphs for Brain Visualization
(The Eurographics Association, 2013)The correlation of spontaneous brain activity, termed: functional connectivity, has become a valuable method in recent years for mapping brain organization. We present a novel approach to visualize functional connectivity ...
