Workshop on Bioimaging II / PDEs, Fri, 23 Nov, 2007
Speaker: Werner Benger
Abstract
Diffusion-tensor magnetic resonance imaging (DT-MRI) is an evolving data acquisition technique. It allows retrieving information about neuronal tissues beyond conventional MR imaging. However, the complexity of these data also challenges visualization technology. The limitations of common approaches to visualize the retrieved data are discussed and the drawbacks of the standard methods of "fibertracking". An alternative visualization method is discussed in the light of neurophysiological considerations on the perception of color patterns. This method is believed to be more accurate for medical data while providing a nearly optimal visual stimulus. It is tested to analyze a tumor using DT-MRI data sets of human brains from a clinical environment.
