Especially on a 2D screen, understanding their full shape and interacting with them is difficult. Critical regions do not always stand out in the visualization and may easily be missed without proper interaction and filtering techniques. The FlowLens [GNBP11] was introduced as a focus-and-context technique to explore one specific blood flow parameter in the context of other parameters for the purpose of treatment planning. With the recent availability of affordable VR glasses it is possible to adapt the concepts of the FlowLens into immersive VR and make them available to a broader group of users. Translating the concept of the Flow Lens to VR leads to a number of design decisions not only based around what functions to include, but also how they can be made available to the user. In this paper, we present a configurable focus-and-context visualization for the use with virtual reality headsets and controllers that allows users to freely explore blood flow data within a VR environment. The advantage of such a solution is the improved perception of the complex spatial structures that results from being surrounded by them instead of observing through a small screen.

The framework is based on a novel shape descriptor of closed contours relying on a geodesically uniform resampling of discrete curves to allow for discrete differential-geometry-based computation of unsigned curvature at vertices and edges. Our descriptor is, by design, invariant under translation, rotation and parameterization. Moreover, it additionally offers the option for uniform-scale-invariance. The optional scale-invariance is achieved by scaling features to z-scores, while invariance under parameterization shifts is achieved by using elliptic Fourier analysis (EFA) on the resulting curvature vectors. These invariant shape descriptors provide an embedding into a fixed-dimensional feature space that can be utilized for various applications: (i) as input features for deep and shallow learning techniques; (ii) as input for dimension reduction schemes for providing a visual reference for clustering collection of shapes. The capabilities of the proposed framework are demonstrated in the context of visual analysis and unsupervised classification of histology images.

Aneurysm treatment must be carefully examined as there is a risk of fatal outcome during surgery. Aneurysm growth, rupture, and treatment success depend on the interplay of vascular morphology and hemodynamics. Blood flow simulations can obtain the patient-specific hemodynamics. However, analyzing the time-dependent, multi-attribute data is time-consuming and error-prone. ANEULYSIS supports the analysis and visual exploration of aneurysm data including morphological and hemodynamic attributes. Since this is an interdisciplinary process involving both physicians and fluid mechanics experts, we provide a redundancy-free management of aneurysm data sets according to a consistent structure. Major contributions are an improved analysis of morphological aspects, simultaneous evaluation of walland flow-related characteristics as well as multiple attributes on the vessel wall, the assessment of mechanical wall processes as well as an automatic classification of the internal flow behavior. It was designed and evaluated in collaboration with domain experts who confirmed its usefulness and clinical necessity.
