Real-time Processing for Advanced Ultrasound Visualization

The continuous advances in the field of medical imaging constantly provide clinicians with new technology promising to facilitate diagnosis, interventions and therapies and improve their outcome. Inherent with this progress is that the amount of available data, its resolution and quality is significantly increasing. However, such improvements are only of actual use if the data can be adequately presented to the clinician. Thus, visual computing in medicine is an important field of research. This thesis focuses on the development of such techniques specifically designed for medical ultrasound.

At first, techniques for improved 2D B-mode ultrasound visualization are presented, where the observer is provided with interactive feedback on the uncertainty present in the image. A novel incremental solver scheme for the computation of ultrasound Confidence Maps allows for real-time estimation of per-pixel uncertainty information based on ultrasound signal attenuation. This information is then fused with the original B-mode images using three carefully chosen visualization schemes for both educational and clinical applications.

The second part of this thesis then introduces an orientation-driven ultrasound compounding approach to create high-quality 3D ultrasound volumes. Finally, a novel classification concept in the form of point predicates is presented, which seamlessly integrates into the standard direct volume rendering pipeline. In conjunction with the proposed predicate histogram as intuitive user interface, this technique allows for much more meaningful visualization and facilitates the understanding of the data for the observer.



CAMPVis: A Game Engine-inspired Research Framework for Medical Imaging and Visualization

Intra-operative visualization has become more and more an essential part of medical interventions and provides the surgeon with powerful support for his work. However, a potential deployment in the operation room yields various challenges for the developers. Therefore, companies usually offer highly specialized solutions with limited maintainability and extensibility As novel approach, the CAMPVis software framework implements a modern video game engine architecture to provide an infrastructure that can be used for both research purposes and end-user solutions. It is focused on real-time processing and fusion of multi-modal medical data and its visualization. The fusion of multiple modalities (such as CT, MRI, ultrasound, etc.) is the essential step to effectively improve and support the clinician's workflow. Furthermore, CAMPVis provides a library of various algorithms for preprocessing and visualization that can be used and combined in a straight-forward way. This boosts cooperation and synergy effects between different developers and the reusability of developed solutions.
