Lecture of Gabriel Lefloch: Visualization and analysis of tensor fields for SAXS tensor tomography

 

Computed Tomography (CT) is a widely used three-dimensional imaging method that makes use of the penetrative capabilities of photons and specialized mathematical algorithms to reconstruct and visualize the internal structures of objects. Small Angle X-ray Scattering (SAXS) enables the probing of nanoscale features in large samples. The combination of SAXS with CT allows for the reconstruction of nanostructures. In the case of tensor tomography, we have not a single scalar value per unit of space, but a structure of information commonly expressed through tensors or spherical harmonics. However, visualizing these high-dimensional data structures is a challenging task, hence the need to develop a visualization tool for these state-of-the-art imaging techniques. Glyph objects are a common mathematical tool used to visualize them. Yet, CT scans produce dense point fields which are expensive to render and hard to interpret. Therefore, one of the main goals is to represent complex multi-faceted information in an easy-to-interpret fashion while maintaining a suitable compromise between the level of detail (LOD), interpretability, and performance.
