Misalignment Correction in Open Cone-Beam CT
(The Eurographics Association, 2014)Cone-beam computed tomography (CBCT) is an established standard for both, medical and industrial volumetric imaging. To compute a 3D volume, multiple 2D x-ray projection images of an object of interest are acquired from ... -
Personalized X-ray Reconstruction of the Proximal Femur via a New Control Point-based 2D-3D Registration and Residual Complexity Minimization
(The Eurographics Association, 2014)In this paper we present a new control point-based 2D-3D registration approach for a deformable registration of a 3D volumetric template to a limited number of 2D calibrated C-arm images and show its application to a ... -
RegistrationShop: An Interactive 3D Medical Volume Registration System
(The Eurographics Association, 2014)In medical imaging, registration is used to combine images containing information from different modalities or to track treatment effects over time in individual patients. Most registration software packages do not provide ... -
Towards Clinical Deployment of Automated Anatomical Regions-Of-Interest
(The Eurographics Association, 2014)The purpose of this work is to investigate, and improve, the feasibility of advanced Region Of Interest (ROI) selection schemes in clinical volume rendering. In particular, this work implements and evaluates an Automated ... -
Visibility-Driven Processing of Streaming Volume Data
(The Eurographics Association, 2014)In real-time volume data acquisition, such as 4D ultrasound, the raw data is challenging to visualize directly without additional processing. Noise removal and feature detection are common operations, but many methods are ... -
Evaluation of Transfer Function Methods in Direct Volume Rendering of the Blood Vessel Lumen
(The Eurographics Association, 2014)Visualization of contrast enhanced blood vessels in CT angiography data presents a challenge due to varying concentration of the contrast agent. The purpose of this work is to evaluate the correctness (effectiveness) in ... -
Visual and Quantitative Analysis of Higher Order Arborization Overlaps for Neural Circuit Research
(The Eurographics Association, 2014)Neuroscientists investigate neural circuits in the brain of the common fruit fly Drosophila melanogaster to discover how complex behavior is generated. Hypothesis building on potential connections between individual neurons ... -
Visualizing Movements of Protein Tunnels in Molecular Dynamics Simulations
(The Eurographics Association, 2014)Analysis and visualization of molecules and their structural features help biochemists and biologists to better understand protein behavior. Studying these structures in molecular dynamics simulations enhances this ... -
Membrane Mapping: Combining Mesoscopic and Molecular Cell Visualization
(The Eurographics Association, 2014)Three-dimensional cell visualization is an important topic in today's cytology-affiliated community. Cell illustrations and animations are used for scientific as well as for educational purposes. Unfortunately, there exist ... -
Interactive Labeling of Toponome Data
(The Eurographics Association, 2014)Biological multi-channel microscopy data are often characterized by a high local entropy and phenotypically identical structures covering only a few pixels and forming disjoint regions spread over, e.g., a cell or a tissue ... -
Imaging the Vascular Network of the Human Spleen from Immunostained Serial Sections
(The Eurographics Association, 2014)The spleen is one of the organs, where the micro-structure and the function on that level are not completely understood. It was for example only recently found that is has an open circulation, which distinguishes it from ... -
Real-Time Dense Nucleus Selection from Confocal Data
(The Eurographics Association, 2014)Selecting structures from volume data using direct over-the-visualization interactions, such as a paint brush, is perhaps the most intuitive method in a variety of application scenarios. Unfortunately, it seems difficult ... -
Uncertainty-aware Ensemble of Classifiers for Segmenting Brain MRI Data
(The Eurographics Association, 2014)Estimating and visualizing uncertainty in medical image segmentation has become an active research area due to the necessity of making medical experts aware of possibly wrong segmentation decisions. Still, to our knowledge ... -
Inlier Detection in Thermal Sensitive Images
(The Eurographics Association, 2014)Image guidance of medical procedures may use thermal images to monitor a treatment. Analysis of the thermal images by the physician may be time consuming and confusing because the thermal image includes multiple outliers. ... -
Extracting and Visualizing Uncertainties in Segmentations from 3D Medical Data
(The Eurographics Association, 2014)Assessing surfaces of segmentations extracted from 3D image data for medical purposes requires dedicated extraction and visualization methods. In particular, when assessing follow-up cases, the exact volume and confidence ... -
A Survey on Visualizing Magnetic Resonance Spectroscopy Data
(The Eurographics Association, 2014)Data from Magnetic Resonance Spectroscopy Imaging (MRSI) contains signals about biomarkers concentrations, which are used to achieve new knowledge about biochemical processes. These support doctors in identifying and treat ... -
The iCoCooN: Integration of Cobweb Charts with Parallel Coordinates for Visual Analysis of DCE-MRI Modeling Variations
(The Eurographics Association, 2014)Efficacy of radiotherapy treatment depends on the specific characteristics of tumorous tissues. For the determination of these characteristics, clinical practice uses Dynamic Contrast Enhanced (DCE) Magnetic Resonance ... -
Robust Cardiac Function Assessment in 4D PC-MRI Data
(The Eurographics Association, 2014)Four-dimensional phase-contrast magnetic resonance imaging (4D PC-MRI) is a relatively young image modality that allows the non-invasive acquisition of time-resolved, three-dimensional blood flow information. Stroke volumes ... -
Guided Visualization of Ultrasound Image Sequences
(The Eurographics Association, 2010)Ultrasonography allows informative and expressive real time examinations of patients. Findings are usually reported as printouts, screen shots and video sequences. However, in certain scenarios, the amount of imaged ... -
Anatomical Volume Visualization with Weighted Distance Fields
(The Eurographics Association, 2010)We describe the use of the weighted distance transform (WDT) to enhance applications designed for volume visualization of segmented anatomical datasets. The WDT is presented as a general technique to generate a derived ...
