VirtualDSA++: Automated Segmentation, Vessel Labeling, Occlusion Detection and Graph Search on CT-Angiography Data
(The Eurographics Association, 2020)
Computed Tomography Angiography (CTA) is one of the most commonly used modalities in the diagnosis of cerebrovascular diseases like ischemic strokes. Usually, the anatomy of interest in ischemic stroke cases is the Circle ...
An Exploration of Practice and Preferences for the Visual Communication of Biomedical Processes
(The Eurographics Association, 2021)
The visual communication of biomedical processes draws from diverse techniques in both visualization and biomedical illustration. However, matching these techniques to their intended audience often relies on practice-based ...
Shading Style Assessment for Vessel Wall and Lumen Visualization
(The Eurographics Association, 2021)
Current blood vessel rendering usually depicts solely the surface of vascular structures and does not visualize any interior structures. While this approach is suitable for most applications, certain cardiovascular diseases, ...
AR-Assisted Craniotomy Planning for Tumour Resection
(The Eurographics Association, 2021)
Craniotomy is a procedure where neurosurgeons open the patient's skull to gain direct access to the brain. The craniotomy's position defines the access path from the skull surface to the tumour and, consequently, the healthy ...
Visual Analysis of Multivariate Intensive Care Surveillance Data
(The Eurographics Association, 2020)
We present an approach for visual analysis of high-dimensional measurement data with varying sampling rates in the context of an experimental post-surgery study performed on a porcine surrogate model. The study aimed at ...
Feature Exploration using Local Frequency Distributions in Computed Tomography Data
(The Eurographics Association, 2020)
Frequency distributions (FD) are an important instrument when analyzing and investigating scientific data. In volumetric visualization, for example, frequency distributions visualized as histograms, often assist the user ...
The Virtual Reality Flow Lens for Blood Flow Exploration
(The Eurographics Association, 2020)
The exploration of time-dependent measured or simulated blood flow is challenging due to the complex three-dimensional structure of vessels and blood flow patterns. Especially on a 2D screen, understanding their full shape ...
VR Acrophobia Treatment - Development of Customizable Acrophobia Inducing Scenarios
(The Eurographics Association, 2020)
Specific phobias are among the most common mental diseases, affecting the lives of millions of people. Yet, many cases remain untreated and even undiagnosed, partly due to entry barriers such as waiting times and inconvenience ...
VRIDAA: Virtual Reality Platform for Training and Planning Implantations of Occluder Devices in Left Atrial Appendages
(The Eurographics Association, 2020)
Personalized anatomical information of the heart is usually obtained from the visual analysis of patient-specific medical images with standard multiplanar reconstruction (MPR) of 2D orthogonal slices, volume rendering and ...
Learning Hand Anatomy with Sense of Embodiment
(The Eurographics Association, 2020)
We present a VR-based prototype for learning the hand anatomy. The prototype is designed to support embodied cognition, i.e., a learning process based on movements. The learner employs the prototype in VR by moving their ...
