GEPARD – Vessel Wall Simulation and Visualization for Patient-Specific Blood Flow Prediction for Intracranial Aneurysm Modeling


We gladly announce the German Research Foundation (DFG) approval for our GEPARD (GEfäßwandsimulation und -visualisierung zur Patientenindividualisierten Blutflussvorhersage für die intrakranielle AneuRysmamoDellierung) proposal. The project was developed by Dr.-Ing. Sylvia Saalfeld and Dr.-Ing. Philipp Berg. The 3-year project comprises two PhD-positions and aims at blood flow simulation and visualization of patient-specific intracranial aneurysms. Intracranial aneurysms and their associated rupture risk have been active research areas of both applicants for the last years. With the GEPARD project, especially the morphology of the intracranial vessel wall and its influence on the subsequent blood flow simulation will be examined. Furthermore, the extravascular space will be incorporated into the analyses as well. The project will be carried out in close cooperation with the neuroradiology department of the university hospital Magdeburg and will be integrated into the Forschungscampus STIMULATE.

2nd Price MedVis Award and presentation in Ulm

A team lead by Patrick Saalfeld recieved the 2nd price of the MedVis-Award (Karl-Heinz-Höhne Award). The price was handed over at the annual meeting of the VCBM working group. The succesful contribution demonstrates how vascular structures and annotations can be sketched interactively to support treamtent planning and medical education. The sketching is performed with the semi-immersive zSpace. Benjamin Behrendt presented his latest work regarding the explorative visualization of cerebral and cardiac bloodflow data at the same meeting.

Funding for 10 Head-worn Displays for collaborative VR research

We installed 10 HTC Vives that allow several users to interact in a shared virtual environment simultaneously. We will use this setup for collaborative VR research and to support lectures and student projects of our faculty with hands-on demonstrations of spatial interaction. The equipment is funded by an internal grant from the Faculty of Computer Science at the Otto-von-Guericke University of Magdeburg.

Cardio Diagnostic Days

We presented a VR prototype at the German Cardio Diagnostic Days in Leipzig, organized by our clinical collaborators Matthias Gutberlet and Matthias Grothoff. The VR protoype is currently extended together with paediatric cardiologist in Dallas, USA. It allows to explore healthy and pathological heart conditions that eventually can support treatment planning and patient education. The feedback the physicians gave us was very positive.

Benjamin Köhler gave a talk about 4D PC MRI data evaluation, demonstrating the analysis of blood flow patterns in the aorta and pulmonal artery with his research software “Bloodline”.

Research Award

Monique Meuschke received the Faculties’s research award for her paper „Combined Visualization of Vessel Deformation and Hemodynamics in Cerebral Aneurysms“ that appeared in IEEE Trans. Vis. Comput. Graph. It was joint work with Samuel Voss from the flow simulation group, Oliver Beuing from the Neuroradiology department and Kai Lawonn from Koblenz University.

Hugo-Junkers Preis

Sylvia Saalfeld presents her work on rupture risk estimation to Minister Willingmann at the final ceremony of the Hugo-Junkers Preis. This is joint work with Philipp Berg (left) from the Dept. for Flow Mechanics and Oliver Beuing from the Neuroradiology Department.

Habilitation Thesis defended

Kai Lawonn successfully defended his Habilitation thesis „Visual Enhancement of Focus Structures in Selected Applications“. In his thesis, Kai summarizes interdisciplinary research with archeologists, engineers and physicians. His newly developed techniques emphasize low-contrast linear structures, visualize multimodal medical image data and improve the visualization of blood flow, vascular structures and wall-thickness.

Honorable Mention Award

Shiva Alemzadeh got an honorable mention award at the VCBM Workshop in Bremen for her work on „Visual Analytics of Missing Data in Epidemiological Cohort Study Data“. This is joint work with KMD group and the epidemiologists from the university of Greifswald. The award is combined with an invitation to submit an extended version to the „Computer Graphics Forum“.

International internships

Several members of the Vis. Group use the summer time for internships at renowned international institutions.
Monique Meuschke and Kai Lawonn stay at ETH Zürich with Dr. Tobias Günther working on blood flow visualization incorporating transparency optimization.
Shiva Alemzadeh joined the VRVis in Vienna for a two-month stay at the MedVis group (Dr. Katja Bühler), where she contributes her visual analytics expertise to analyze gene expression data.
Gabriel Mistelbauer continues his long-term cooperation with the Stanford university, staying with medical doctor Dominik Fleischmann. Their joint interest is smart vessel visualization.
