Visualization & Exploration of Blood Flow in Aneurysms

test focus_context.jpg mesh.jpg wss.jpg










Due to the current advances in the field of medical imaging and an increase of MR and CT brain scans as part of diagnostic procedures, the number of cerebral aneurysm findings is rising. These dilated parts of cerebral arteries exhibit a high risk of rupture, which can lead to internal bleedings with fatal consequences for the patient (mortality rate: up to 60%). To reduce the risk for the patient most of the interventions are performed minimal invasive by filling the aneurysm with small metal coils (Coiling) and stabilizing them with a tubular metal mesh (Stent) if necessary. Since the intervention itself involves the risk of causing an internal bleeding, a detailed risk estimation and a deeper insight into the blood flow dynamics, that influence the development of cerebral aneurysms, is crucial. In current research computational fluid dynamics (CFD) simulation is the common approach to gain a better understanding for the dynamic characteristics of the internal blood flow.

The result of the CFD simulation is a multidimensional and often time dependent dataset. Our aim is to develop an application-specific pipeline to make this complex data accessible to medical researchers. Besides different approaches to visualize the flow characteristics this pipeline also needs to contain the analysis of morphological features and their relation to the flow characteristics. One application of this pipeline is the creation of expressive comparison visualizations in order to gain insight into the development of an aneurysm over time or into the affect a change in the incoming blood-flow has onto the whole dynamic system. Due to the interdisciplinary character of this research area we are working together with Institute of Neuroradiology (medical experts), the Institute of Fluid Dynamics and Thermodynamics (CFD simulation), the Image Processing Workgroup (segmentation), the Institute of Electronics, Signal Processing and Communication Technology (evaluation of the CFD simulation). In October 2008 this cooperation formed the base for the Mobestan project supported by the state of Saxony-Anhalt.

A short summarization of our current field of research:

  • Semi-/automatic extraction and visualization of morphological information and flow features
  • Guided exploration and overview visualization of complex flow datasets
  • Focus & Context visualization of cerebral vasculature
  • Combined (internal flow data – surface morphology) and comparing (change over time, after stent application, etc.) visualizations

Investigating Vortical Flow in a Giant Aneurysm
The video illustrates our pipeline for investigating vortices in simulations of cerebral aneurysm hemodynamics. The demonstration case is a giant aneurysm of the left internal carotid artery (ICA) at the origin of the ophtalmic artery. The corresponding hemodynamic data was generated by Juan R. Cebral. In a first step, vortex core line segments are extracted from time step t of the simulation data and continuous core lines are formed in an enhancement step. Then, streamlines are integrated from core line points. To reduce visual clutter, streamlines are grouped based on equilibrium points along the core lines. The groups may be optionally refined in a clustering step generating a more detailed visualization of the flow pattern, especially further off the core lines. Finally, group/cluster representatives are computed and integrated with other simulated or derived data in a visual summary. The aneurysm at hand contains three major vortices. Among them is a so-called embedded vortex. This type of vortex is characterized by a vortex layer swirling in one direction along the vortex core line, and a second vortex layer swirling in the opposite direction and enveloping the first. The video illustrates a smart visibility strategy supporting the investigation of flow in the presence of multiple vortices. In an overview visualization, the representatives of all vortices are displayed. As the user zooms in on a vortex, all other vortices gradually disappear. If the user continues to zoom in, the representatives of the vortex in focus also start to fade-out and its spherical glyphs gradually shrink to reveal the core line and facilitate an inspection of its velocity magnitude profile.

Clustering Blood Flow in a Saccular Side-Wall Aneurysm
The blood flow in a saccular side-wall aneurysm has been simulated based on the vascular morphology extracted from patient-individual data. The resulting flow data is often visualized by a dense and cluttered set of streamlines. Clustering the streamlines and computing cluster representatives reduces visual clutter and exposes characteristic flow structures. The resulting flow summary benefits the assessment of aneurysmal hemodynamics.

Video
The video presents the automatically extracted inflow jet and impingement zone of a steady flow dataset in a cerebral aneurysm. The extraction approach is based on the inflow streamlines seeded at the ostium and employs local streamline properties (e.g., curvature and distances to the aneurysm wall). Several visualization techniques depict both characteristics.

Lens-Based Flow Exploration of Cerebral Aneurysms
This video presents the FlowLens concept, a visual exploration approach of blood flow data in cerebral aneurysms. Relevant hemodynamic attributes, e.g., wall shear stress or pressure, are grouped to focus-and-context pairs and assigned to three different spatial scopes (global, near-wall, aneurysm). A 2.5D lens shape is used to embed locally the visualization of the context attribute within the focus attribute.

Anatomy-Guided Multi-Level Exploration of Blood Flow
We present a three-scope approach for qualitative visual exploration of blood flow data. The scopes include a global scope, an ostium scope and a local scope. They are related to anatomic features such as the centerline, the ostium or the central aneurysm axis. The exploration includes multi-parameter visualisations and specialized widgets.

Reconstruction of the Ostium
This video presents an approach to automatically extract important landmarks and geometrically reconstruct the ostium. As shown, the ostium can be used to seperate the aneurysm from the parent vessel. It forms the basis for a variety of applications, e.g. feature-aware visualization or guided interaction.
