Title: Rendering and interacting with large scale volumetric data for medical applications
Abstract: This talk will present recent advances in medical volume rendering from the Center for Medical Image Science (CMIV) and the Norrköping Visualization and Interaction Studio (NVIS), both at Linköping University in Sweden. The first part of the talk will address the issue of data reduction and multi resolution representations for Level-of-Detail selection using the knowledge encoded in transfer functions. Knowledge encoding can also be used to obtain fuzzy classification of unsegmented data and it will be demonstrated how classification can be used to improve transfer function design and enhance features of interest. Other aspects of medical volume rendering such as the use of illumination models to enhance depth cues and to convey additional information from other co-registered sources will also be covered. The second part of the talk will present methods for haptic (force feedback) interaction with volumetric data. New methods for the design and implementation of haptic modes for medical data will be presented and haptic feedback for time resolved volumes will be demonstrated. Throughout the presentation medical examples of volume rendering will be shown such as full body virtual autopsies using the presented methods.
Speaker: Professor Anders Ynnerman received a Ph.D. in physics from Gothenburg University. During the early 90s he was doing research at Oxford University, UK, and Vanderbilt University, USA. In 1996 he started the Swedish National Graduate School in Scientific Computing, which he directed until 1999. From 1997 to 2002 he directed the Swedish National Supercomputer Centre and from 2002 to 2006 he directed the Swedish National Infrastructure for Computing (SNIC).
Since 1999 he has held a chair in scientific visualization at Linköping University and in 2000 he founded the Norrköping Visualization and Interaction Studio (NVIS). NVIS currently constitutes one of the main focal points for research and education in computer graphics and visualization in the Nordic region. He is also one of the co-founders of the Center for Medical Image Science and Visualization (CMIV) and he is currently the chair of the CMIV scientific council. He is involved in several spin-off companies in the area of visualization and scientific computing. Ynnerman’s current research interest lies in the area of visualization of large scale and complex data sets with a focus on volume rendering and multi-modal interaction.
Ynnerman is an elected member of the Swedish Royal Academy of Engineering Sciences and a board member of the Swedish Research Council. In 2007 Ynnerman was awarded the Akzo Nobel Science award and the Golden Mouse award for Swedish IT-person of the year. In 2007 he co-chaired the EuroVis conference and in 2008 he co-chaired the Symposium on Volume Graphics. He is the general chair of Eurographics 2010 organized by Linköping University.
