Extra Colloquia Computing Science

 

  

Date:                          Friday, 1 February 2008                        

Room and time:        5161.0267 (Bernoulliborg), 11.00-13.00

 

 

On February 1, 2008 Michael ten Caat will defend his PhD thesis “Multichannel EEG Visualization” (16.15, Academy building).

On this occasion there will be two extra Colloquia Computing Science.

 

The program is as follows.

 

11.00-11.45     Prof.dr.-Ing.B. Preim (Otto-von-Guericke-Universität Magdeburg) 

                        Visual Computing for medical education, diagnosis and treatment planning

11.45-12.15     Break

12.15-13.00     Prof.dr.ir. J.J. van Wijk (Eindhoven University of Technology)                                                          

                        Visualization of Seifert Surfaces

 

Abstract Preim

This talk covers a variety of algorithms and applications in medical education and medical practice.

Illustrative rendering, visualization of vascular structures and visual analysis of perfusion data are

described in more detail. Major application areas are ENT (Ear, Nose, Throat) surgery planning,

liver surgery training and visualization of the coronary heart disease.

 

 

Abstract van Wijk

Seifert surfaces are an important concept in knot theory, which itself is a branch of topology.

A Seifert surface is an orientable surface that is bounded by a mathematical knot or link. They

are called after Herbert Seifert, a German mathematician who has developed a simple algorithm

to find such surfaces. Still, the shape and structure of these surfaces is hard to understand. We

have developed a method and a tool to define and view such surfaces for arbitrary knots. During

the presentation an extensive demo will be given and many intriguing shapes, images and animations

will be shown.
