VCBM Honorable Mention Award

The paper from Sylvia Glaßer and colleagues “How to Evaluate Medical Visualizations on the Example of 3D Aneurysm Surfaces” was distinguished with the Honorable Mention Award at this years VCBM workshop in Bergen. Sylvia will be invited to submit an extended version of the paper to the Computer Graphics Forum journal.

New Member of the Vis Group

We are glad that Dr. Gabriel Mistelbauer, TU Vienna joins our team. Gabriel brings a lot of experience in all parts of medical visualization, in particular in visualization of vasculature for diagnosis.

100th defense of a Master thesis in the Visualization group

Jean Michel Pape successfully defended his thesis on “Ein Klassifikationssystem zur quantitativen Analyse von Krankheitssymptomen im Kontext der Hochdurchsatz-Phänotypisierung von Pflanzen”. The work was carried out at the Leibniz Institute for Plant Genetics in Gatersleben; a nice piece of interdisciplinary work, typical for the Computational Visualistics degree programme that requires substantial understanding of plant biology and imaging in that area. Advanced cameras that also acquire near infrared light were employed to assess pathologies of plants.

Vis-Group at VIS

We are happy to announce that we will present two papers at this year’s IEEE Visualization Conference (VIS) in Baltimore, Maryland.

“Visualization and Extraction of Carvings for Heritage Conservation” Kai Lawonn, Erik Trostmann, Bernhard Preim, Klaus Hildebrandt.

“Combined Visualization of Vessel Deformation and Hemodynamics in Cerebral Aneurysms” Monique Meuschke, Samuel Voss, Oliver Beuing, Bernhard Preim, Kai Lawonn.

Postdoctoral Lecture Qualification defended

Steffen Oeltze-Jafra defended his Postdoctoral lecture qualification on “Visual Analytics of Medical and Biological Data”. Steffen did a whole bunch of work on analyzing blood flow data, biological data and supervised also work on epidemiology data. With Jarke van Wijk and Thomas Ertl we had great reviewers to discuss all contributions carefully.

PhD Thesis defended

Paul Klemm successfully defended his Phd thesis on “Interactive Visual Analysis of Population Study Data”. Paul developed a couple of methods to enhance the hypothesis-driven workflow of epidemiologists adding data mining and visual analytics to their statistics-driven pipeline. We had a lively discussion with Silvia Miksch (Vienna Institute of Technology) and Daniel Weiskopf (University of Stuttgart) on many issues, including appropriate evaluation methods.

Vis-Group at EuroVis

We are happy to announce that we will present two papers at this year’s Eurographics Conference on Visualization (EuroVis) in Groningen, Netherlands.

“A Survey of Perceptually Motivated 3D Visualization of Medical Image Data” Bernhard Preim, Alexandra Baer, Timo Ropinski, Tobias Isenberg und Douglas Cunningham.

“Semi-automatic Vortex Flow Classification in 4D PC-MRI Data of the Aorta” Monique Meuschke, Benjamin Köhler, Uta Preim, Bernhard Preim, Kai Lawonn.

We are looking forward to it!

PhD Thesis submitted

Benjamin Köhler has submitted his Phd thesis on the visual exploration and analysis of cardicac blood flow. In his thesis, Ben developed BloodLine, a comprehensive tool to preprocess and visualize 4D PC-MRI data with vortex detection, robust quantification of flow features, such as flow rate. BloodLine was developed in close cooperation with the Heart center Leipzig and is regularly used there. Ben’s work is truly application-oriented and resulted in several prices including the MedVis-Award and the Eurographics Medical Price. Ben will stay with us and continue in the recently approved DFG project; extending BloodLine such that larger studies can be more efficiently analyzed.

Cooperation with the Heart Center in Leipzig

We are very glad to announce that the German Research Foundation approved funding for our joint proposal with the Heart Center in Leipzig (Prof. Gutberlet, PD. Grothoff) and the Biometry department in Magdeburg (Prof. Kropf). The 2-year project serves as extension of our research on the visualization and analysis of cardiac blood flow measured with 4D phase-contrast MRI.

In a larger collective of patients and healthy volunteers we want to obtain an improved understanding where the boundary between physiological blood flow variations and pathologies is. The project also comprises the acquisition of patient follow-ups. Their evaluation shall help to better comprehend the evolution of the examined diseases: Bicuspid aortic valves, with a prevalence of 1-2% the most common aortic valve malformation, and tetralogy of Fallot, the most common inherited cyanotic heart disease.

Eurographics PhD Award

Kai Lawonn will be awarded with the Eurographics Phd Award at this year’s Eurographics main conference in May for his thesis “Illustrative Visualization of Medical Datasets”. This prestigeous price is awarded to only two researchers.
