Tomography: Big Scientific Computing to enable Big Science

Joost Batenburg (CWI en Leiden)


Abstract: This talk is about Tomography: computing an image of an object from a series of its projections, obtained using a scanning device. In recent years, X-ray and electron tomography have developed into advanced fields of experimental research, utilizing not just the absorption contrast, but also phase, chemical and directional information to characterize the interior structure of the scanned object. Achieving the best possible results is becoming more and more an interdisciplinary effort, combining state-of-the-art experimental hardware, careful experiment design, mathematical modelling, customized algorithms and high performance computing.In the Computational Imaging group at CWI we develop theory, tools and methodology that can be used to study these steps in an integral framework. In this lecture I will give an overview of our efforts to deal with the massive computational challenges involved in modern tomography, by a combination of efficient algorithms, parallel and distributed computing, and a flexible software framework.
