The rapid progress in medical imaging technology generates rapidly increasing amounts of 3D image data creating a pressing need of finding efficient methods for exploring and evaluating such data. In addition to our work on microscopy as described in the previous paragraphs, we are also working more generally on visualization and interaction methods and on medical application for this. We are currently planning to expand our activites in this field by creating a visualisation lab.
Bengtsson has for several years had a productive collaboration with Anders Hast and Tony Barrera on fundamental graphics algorithms, e.g., for shading. Stefan Seipel is working mainly at University College of Gävle, but 20% of his time with CBA. His research activities are in the field of "efficient visualizations'' with a focus at designing expressive visualization techniques to enhance interpretation by the human observer. One of his projects deals with collaborative 3D visualization, another one with the visualisation of multivariate volume data. He has also carried out a more special project on realistic rendering of ice.
In another group of projects, we are exploring the use of haptic interaction as an added information channel in 3D medical data exploration. So far MR angiographic data, CT data from the liver, and dynamic breast MR data have been used. Ingela Nyström is heading this project with PhD students Erik Vidholm and Suthakar Somaskandan.
