A new 5-year period of funding for interventional radiology and related technical developments starts today in the framework of the research campus SIMULATE. Our group is involved in two subprojects: “image analysis and visualization” (for planning interventions) where we take the lead as well as hemodynamics/tools, where stents and related devices are developed for improving treatment of vascular diseases.
We initiated a tutorial submission together with Anna Vilanova, TU Delft for a full day tutorial including a panel discussion at MICCAI. Tutorial speakers include Stefan Bruckner (Bergen), Katja Bühler (Vienna), Eduard Gröller (Vienna), Markus Hadwiger (KAUST), Bernhard Kainz (London) Thomas Schultz (Bonn), Rüdiger Westermann (Munich), Anders Ynnerman (Linköping).
We submitted two surveys to the electronic archive arXiv. The first survey Feature Lines for Illustrating Medical Surface Models: Mathematical Background and Survey written by Kai Lawonn and Bernhard Preim is about feature lines. Here, several feature line methods are presented and analyzed. Furthermore, this survey provides also the discrete differential geometry background, which is necessary for understanding the feature line concepts.
The second survey by Bernhard Preim et al. was a joint work with the visualization group of Bergen headed by Helwig Hauser, the image processing group headed by Klaus Tönnies, and Henry Völzke the head of the study of health in Pomerania. The survey Visual Analytics of Image-Centric Cohort Studies in Epidemiology discusses cohort studies and how they can be evaluated with visual analytics.
We are proud that our article “Blood Flow Clustering and Applications in Virtual Stenting of Intracranial Aneurysms”, which appeared this year in IEEE Transactions on Visualization and Computer Graphics and was authored by Steffen Oeltze, Dirk J. Lehmann, Alexander Kuhn, Gabor Janiga, Holger Theisel, and Bernhard Preim, has been recognized by NeuroNews. The accompanying video of our article was embedded in their web page.
Kai Lawonn gives an invited talk at MPI in Saarbrücken about illustrative visualization.
After many years of development the Dornheim Segmenter (http://www.segmenter.de/) is now released as a product by our Spin-Off Company Dornheim Medical Images. It is based on research in our group primarily in computer-assisted ENT surgery. Former members of the group, such as Jana Dornheim, Kerstin Kellermann and Tobias Mönch contributed a lot.
The Phd thesis of Kai Lawonn was selected the best Phd thesis of the Faculty in the academic year (1. 10. 2013 – 30. 9. 2014).
Kai Lawonn has successfully defended his Phd thesis on “Illustrative Visualization of Medical Datasets” September, 15. Kai made a number of contributions related to feature lines applied to medical surface meshes. A systematic comparison of existing techniques, the development of new techniques, bridging between feature lines and hatchings, new applications in virtual endoscopy and molecular dynamics. Also for visualizing vascular surfaces along with internal blood flow Kai could strongly improve over existing methods. All this was accomplished in only 2.5 years. The Phd committee rated his performance as “Summa cum laude”.
We are happy to announce that we will present four papers at this year’s Eurographics Workshop on Visual Computing for Biology and Medicine (EG VCBM) in Vienna, Austria.
“A Comparative User Study of a 2D and an Autostereoscopic 3D Display for a Tympanoplastic Surgery” Alexandra Baer, Antje Huebler, Patrick Saalfeld, Douglas Cunningham, Bernhard Preim.
“Robust Cardiac Function Assessment in 4D PC-MRI Data” Benjamin Köhler, Uta Preim, Matthias Gutberlet, Katharina Fischbach, Bernhard Preim.
“Survey of Labeling Techniques in Medical Visualizations” Steffen Oeltze-Jafra, Bernhard Preim.
