Talk of Kuangyu Shi about his previous work on Flow Visualization and current work on Extracting Hypoxia from PET Images

Kuangyu Shi did his Phd on the topics of Dynamical Flow Visualization, Scientific Visualization and Flow Analysis at the Computer Graphics Group at "Max-PLanck-Institut für Informatik" under supervision of Prof. Dr. Holger Theisel and Prof.Dr. Hans-Peter Seidel. For more information please see here.

Kuangyu is currently a Post Doc at the Radiation Therapy of Rechts der Isar with Prof. Wilkens, where he works on extracting hypoxia from PET images.

In his talk, Kuangyu will give an overview of his previous and current work in two parts.

Part I: Path-line Oriented Visualization of Dynamical Flow Fields

Abstract.   An effective visual representation of dynamical flow behaviour is still a challenging problem of modern flow visualization. Path-lines are important characteristic curves of dynamical flow fields. In this part of my talk, we focus on the visual analysis of path-line behaviours and uncover the dynamical nature of a flow field. We investigate the morphological behaviour as well as the physical mechanisms behind the flow behaviour and make detail studies on the topological structure, interactive feature extraction and transport mechanisms. We also demonstrate our approaches on a number of applications and present some interesting results.

Part II: Extracting Hypoxia from PET Images

Abstract.   In this part of the talk, we will go through the general ideas of hypoxia in solid tumours, its impact for radiotherapy and the identification of hypoxia on biological images. We will discuss the current models such as SUV and dynamic models to identify the hypoxic areas in tumours and their application in radiation treatment planning.
