Abstract Rich material data is complex, large and heterogeneous, integrating primary secondary non‐destructive testing for spatial, spatio‐temporal, as well high‐dimensional analyses. Currently, materials experts mainly rely on conventional desktop‐based systems using 2D visualisation techniques, which render respective analyses a time‐consuming mentally demanding challenge. MARV novel immersive visual analytics system, makes of such more effective engaging in an augmented reality setting....
Dynamic contrast-enhanced image data (perfusion data) are used to characterize regional tissue perfusion. Perfusion consist of a sequence images, acquired after contrast agent bolus is applied. for diagnostic purposes in oncology, ischemic stroke assessment or myocardial ischemia. The evaluation perfusion challenging, since the complex and exhibits various artifacts, e.g., motion artifacts. We provide an overview on existing methods analyze, visualize CT MR data. integrated visualization...
The study was approved by the institutional review board, and informed consent obtained. purpose of to prospectively quantify angular visibility range, determine existence orthogonal viewing pairs, characterize conditions that cause artifacts in multipath curved planar reformations (MPCPRs) peripheral arterial tree 10 patients (eight men two women; mean age, 69 years; 54-80 years) with occlusive disease. Percentage segments maximal possible score 1 significantly greater (odds ratio, 1.42;...
Technical developments in neurobiology have reached a point where the acquisition of high resolution images representing individual neurons and synapses becomes possible. For this, brain tissue samples are sliced using diamond knife imaged with electron-microscopy (EM). However, technique achieves low cutting direction, due to limitations mechanical process, making direct visualization dataset difficult. We aim increase depth volume by adding new image slices interpolated from existing ones,...
Abstract Dashboards are used ubiquitously to gain and present insights into data by means of interactive visualizations. To bridge the gap between non‐expert dashboard users potentially complex datasets and/or visualizations, a variety onboarding strategies employed, including videos, narration, tutorials. We propose process model for that formalizes unifies such diverse strategies. Our introduces loop alongside usage loop. Unpacking reveals how each strategy combines selected building...
To compare diagnostic performance and time efficiency between 3D multipath curved planar reformations (mpCPRs) axial images of CT angiography for the pre-interventional assessment peripheral arterial disease (PAD), with digital subtraction as standard reference.Forty patients (10 females, mean age 72 years), referred to CTA prior endovascular treatment PAD, were prospectively included underwent angiography. A semiautomated toolbox was used render mpCPRs. Twenty-one segments defined in each...
The visualization of analytically defined dynamical systems is important for a thorough understanding the underlying system behavior. An overview theoretical concepts concerning given. Various techniques are discussed. Three current research directions treated in more detail. These are: texture based techniques, high-dimensional systems, and advanced streamsurface representations.
There is a wide range of visualization techniques for dynamical systems. These methods are used to visualize certain properties as, e.g., stability fixed points, characteristic changes velocity, and bifurcations. This paper gives short introduction system describes several techniques. Some those applied three different system. The application systems shows how scientific can be analyzing the behavior systems, make analysis fast efficient.
'Shadow profiling' measures shadow durations on an arbitrary scene during several hours of a specific day or even weeks months. The result is to be displayed visually. We shortly discuss already known techniques like simplified radiosity discontinuity meshing with regard their suitability for this problem. Due various drawbacks these techniques, we present our won approach. Especially pixel-oriented version works very efficiently in connection fast polygon-oriented algorithms. It can applied...
Nonlinear deterministic dynamical systems often exhibit complex and chaotic behavior which is difficult to comprehend. Visualizing the characteristics of such therefore essential for an understanding underlying dynamics. In this paper concepts interactive graphical exploration analytically defined are discussed. Emphasis put on interactivity shall facilitate investigation systems. The following topics treated in more detail: specification, simple fast representation, modification....
