Illustrative Visualization Techniques

In different research areas illustrative visualization techniques are used to convey complex information in a simplified and more abstract manner. These techniques have their origin in traditional illustration techniques like pen-and-ink techniques (e.g., stippling and hatching) and smart visibility techniques (e.g. ghosted and exploded views). Often, they are adapted to a certain application to enhance important information, such as surface shape, depth, focus-and-context relations and spatial relationships.

In our working group, we focus on both the development and improvement of existent illustrative visualization techniques and their application to several medical research areas, such as blood flow visualization and treatment planning. Thereby, we incorporate related topics that are necessary to extract the important information, e.g., differential geometry, vector field analysis and advanced GPU programming. The effectivness of the investigated and proposed techniques are assessed by means of perceptual evaluation studies.

A short summarization of our current field of research:

  • Developing of illustrative rendering techniques
  • Adapting and extending of existent techniques for anatomical structures and scenes
  • Evaluation of these techniques in a medical context is done by the perceptual evaluation research project

Illustrative Multi-volume Rendering for PET/CT Scans
Abstract?In this paper we present illustrative visualization techniques for PET/CT datasets. PET/CT scanners acquire both PET and CT image data in order to combine functional metabolic information with structural anatomical information. Current visualization techniques mainly rely on 2D image fusion techniques to convey this combined information to physicians. We introduce an illustrative 3D visualization technique, specifically designed for use with PET/CT datasets. This allows the user to easily detect foci in the PET data and to localize these regions by providing anatomical contextual information from the CT data. Furthermore, we provide transfer function specifically designed for PET data that facilitates the investigation of interesting regions. Our technique allows users to get a quick overview of regions of interest and can be used in treatment planning, doctor-patient communication and interdisciplinary communication. We conducted a qualitative evaluation with medical experts to validate the utility of our method in clinical practice.

We present a novel line drawing algorithm that illustrates surfaces in real-time to convey their shape. We use line integral convolution (LIC) and employ ambient occlusion for illustrative surface rendering. Furthermore, our method depicts salient regions based on the illumination gradient. Our method works on animated surfaces in a frame-coherent manner. Therefore, it yields an illustrative representation of time-dependent surfaces as no preprocessing step is needed. In this paper, the method is used to highlight the structure of molecular surfaces and to illustrate important surface features like cavities, channels, and pockets. The benefit of our method was evaluated with domain experts. We also demonstrate the applicability of our method to medical visualization.

The investigation of hemodynamic information for the assessment of cardiovascular diseases (CVDs) gained importance in recent years. Improved flow measuring modalities and computational fluid dynamics (CFD) simulations yield in reliable blood flow information. For a visual exploration of the flow information, domain experts are used to investigate the flow information combined with its enclosed vessel anatomy. Since the flow is spatially embedded in the surrounding vessel surface, occlusion problems have to be resolved. A visual reduction of the vessel surface that still provides important anatomical features is required. We accomplish this by applying an adaptive surface visualization inspired by the suggestive contour measure. Furthermore, an illustration is employed to highlight the animated pathlines and to emphasize nearby surface regions. Our approach combines several visualization techniques to improve the perception of surface shape and depth. Thereby, we ensure appropriate visibility of the embedded flow information, which can be depicted with established or advanced flow visualization techniques. We apply our approach to cerebral aneurysms and aortas with simulated and measured blood flow. An informal user feedback with nine domain experts, we confirm the advantages of our approach compared with existing methods, e.g. semi-transparent surface rendering. Additionally, we assessed the applicability and usefulness of the pathline animation with highlighting nearby surface regions.

The expressive visualization of (time-dependent) 3D blood flow along with the vessel wall is essential for understanding vascular diseases. However, the high complexity of the underlying flow data makes the exploration challenging. For the biomedical research, it is necessary to provide methods that allow for rapid flow comprehension, ideally by emphasizing relevant flow characteristics. Therefore, we present a fast approach that visualizes streamlines in a view-dependent way, while taking relevant flow features into consideration. For this, we adapt a well-established non-photorealistic rendering technique (suggestive contours) for surface meshes to streamline illustrations. The advantages of our approach are confirmed in an informal user feedback with domain experts, who were able to comprehend the overall flow behavior faster.
