04/29/2016 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!
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.
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.
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.
11/03/2016: Virtual Anatomy – Explorative Study
We conducted our first explorative study for our BMWi funded project Virtual Anatomy together with our project partners Dornheim Medical Images GmbH and the Institute of Anatomy.
On February 16th and 18th, we invited ca. 20 medical students each day. After an assessment of their spatial ability, the students were split in two groups. Each group had to elaborate a medical scenario, one with an established approach, i.e., anatomy atlases, and the other with the application Dornheim Segmenter, respectively. After that, the students were tested on their abilities to label different structures on a body donor as well as recreate a medical region in a puzzle.
We thank all medical students for participation. This kind of a well planned and executed study with end users, was the first in our group. Now we are excited to analyze and interpret the results!
Steffen Oeltze-Jafra submitted his postdoctoral lecture thesis (“Habilitation”) on “Visual Analytics of Medical and Biological Data” summarizing his work on exploring blood flow data, toponome data and data from neuro science studies. It will be the first habilitation in our group.
Ivo Rössling, external Phd candidate of our group and staff member of Dornheim Medical Images successfully defended his Phd thesis “Vermessung von medizinischen Segmentierungen für die chirurgische Interventionsplanung und Dokumentation”. Ivo was actively involved in our long term cooperation with the University hospital Leipzig, being core developer of the TumorTherapyManager that is regularly used for Tumorboard meetings.
We are very happy that Pere-Pau Vazquez (associate professor from Barcelona) visits us. Pere-Pau is an expert in viewpoint selection, volume rendering and in particular perceptual enhancements of existing techniques. We are looking forward to his talk on “Instant Visualization of Molecular Simulation”.
Noeska Smit from Delft University of Technology is with us for a 10 day stay. Noeska is a specialist in medical visualization in general and in anatomy education in particular. She gave a talk on “The Virtual Surgical Pelvis”.
Welcome to Kai Nie, our new staff member from China. Kai will work on the visual analysis of perfusion data taking into account contrast agent dynamics, morphology and texture of suspicious tumors.
Paul Klemm has submitted his Phd thesis “Interactive Visual Analysis of Population Study Data”, an essential result from our DFG project together with Klaus Toennies and Henry Völzke from the University of Greifswald. This work was part of the DFG priority programme “Scaleable Visual Analytics”.
Our new staff member Monique Meuschke got a prestigeous award last Saturday. Having the best possible grades in all subjects, Monique was selected as the best graduate of all our six master programmes.
We welcome Nico Merten as new staff member working in the Research Campus SIMULATE. Before joining the Vis group Nico studied Computational Visualistics at Koblenz-Landau University.

09/10/2015: Phd Thesis defended
Alexandra Baer defended here Phd thesis on “Perception-Guided Evaluation of 3D Medical Visualizations” successfully. Alexandra conducted a series of controlled perceptual studies related to emphasis techniques in medical visualization, depth perception with stereo and autostereoscopic devices and related to visualizations of vascular structures and internal flow. The thesis was reviewed by Timo Ropinski (Ulm University) and Douglas Cunningham (BTU Cottbus) and was graded with a Magna Cum Laude from all three reviewers.
07/10/2015: Project “Virtual Anatomy” funded
The new project “Virtual Anatomy”, funded by the Federal Ministry for Economic Affairs and Energy starts on October 1st. During the next 2.5 years, innovative concepts shall be developed and tested to modernize the anatomy education. For example, the body donors that are used by medical students for preparation training are scanned in high resolution such that the preparation can also be simulated virtually. While the body donors can only be used for a limited time, the virtual models are basically always available. One of the practical research questions is how to directly integrate the viewing and analysis of 3D models into the curriculum of the anatomy education.
The project is headed by Dornheim Medical Images. The company brings their competencies in the segmentation of medical image data. Furthermore, the Institute of Anatomy (Prof. Rothkötter) and the Visualization Group (Prof. Preim) of the University of Magdeburg are involved in the project. The developed solutions are tested and refined at the Institute of Anatomy. The Visualization Group supports the project with their experience in medical training systems and realizes innovative visualization techniques for the resulting complex data.

30/07/2015: Excellent Master Thesis and Phd Thesis defended
Monique Meuschke provided an extraordinary Master thesis analyzing aortic blood flow data. Monique developed techniques to automatically classify vortices with respect to the stage in cardiac cycle (systolic, diastolic), to their extent (major and minor flow), flow direction, helical or vertical flow and the aortic section where the vortex occurs. All criteria are defined manually so far according to many clinical publications. Monique could develop methods that are quite robust and precise according to evaluations with real (pathologic patient data). The excellently written and presented thesis was judged with the highest possible grade by both reviewers. We are happy that Monique now joins the STIMULATE team, in particular the hemodynamics group.
Juliane Dinse external Phd student of the Vis group and staff member at MPI Leipzig defended her thesis. She dealt with neuroanatomical modelling looking for both the myeloarchitecture and the cytoarchitecture of human brains. She processed and analyzed histological images of human brains and 7 Tesla MR images using various theories and models to correlate them with each other. For this work, Juliane was awarded with a MICCAI Young Investigators award in 2013. This year she could publish a comprehensive paper in NeuroImage. Due to the excellent feedback from the external reviewers, both specialized in neurological image processing, Dorit Merhof (RWTH Aachen) and Guido Gerig who recently moved to New York the thesis was judged as “Summa Cum Laude”.

15/03/2013: 10 Jahre AG Visualisierung
09/18/2010: “Karl-Heinz-Höhne MedVis-Award”
“Nachwuchswissenschaftler für ihre Arbeit geehrt - Computerunterstützung für die klinische Anwendung”
Die Fachgruppe “Visual Computing in der Medizin” der Gesellschaft für Informatik vergibt am 18. November 2010 zum vierten Mal den Karl-Heinz-Höhne MedVis-Award, für den das Münchener Medizintechnikunternehmen BrainLAB AG das Preisgeld stiftete.
Ausgezeichnet wurden Nachwuchswissenschaftler, die mit ihren Arbeiten einen wichtigen Beitrag für die Nutzung bildgebender Verfahren in der Diagnostik und Therapie geleistet haben. Eine Jury aus 15 Experten, geleitet von Bernhard Preim (Universität Magdeburg) und Stefan Zachow (Zuse-Institut Berlin) hat die 18 eingereichten Arbeiten sorgfältig bewertet und verglichen.
Mit dem 1. Preis wird Christian Dick, Technische Universität München geehrt. Ihm ist es gelungen, biomechanische Simulationen mit der interaktiven Darstellung von CT-Daten zu kombinieren, um damit orthopädische Operationen, speziell an der Hüfte besser planen zu können. Seine Simulationsmethode nutzt dabei die programmierbare Grafikhardware und ist dadurch um Größenordnungen schneller als bisherige Verfahren - so dass die Simulationen erstmals direkt im Rahmen einer interaktiven Planung eingesetzt werden können.
Mit dem 2. Preis wurde Christian Rieder, Fraunhofer MEVIS Bremen, geehrt. Seine Arbeit dient vor allem der Planung von Tumoroperationen im Gehirn und an der Leber. Er kombiniert dabei verschiedene Darstellungstechniken geschickt und ermöglicht so, die Integration aller relevanten Informationen in aussagekräftigen 3D-Visualisierungen. So sehen die Mediziner z.B. besser, wie sie eine Applikatornadel platzieren können, die den Tumor durch Wärmewirkung bei Anwendung der Radiofrequenztherapie zerstören soll.
Aufgrund der besonders hohen Qualität der eingereichten Beiträge wurden zwei 3. Preise vergeben.
Dagmar Kainmüller vom Zuse-Institut Berlin wird für ihre Arbeit zur automatischen Segmentierung von anatomischen Strukturen ausgezeichnet. Vereinfacht gesagt, gelingt es ihr durch eine komplizierte mathematische Modellierung von anatomischen Formen und Bildinformationen, eine Struktur, z.B. ein Organ in einem Datensatz automatisch korrekt abzugrenzen. Solche Segmentierungsmethoden sind meist die Voraussetzung für die Generierung aussagekräftiger Visualisierungen der 3D-Anatomie.
Konrad Mühler, Universität Magdeburg, hat eine Vielzahl von Algorithmen, z.B. zur automatischen Beschriftung von medizinischen 3D-Modellen entwickelt und in eine frei verfügbare Software-bibliothek zur Implementierung medizinischer Visualisierungskomponenten integriert. Andere Entwickler müssen somit “das Rad nicht immer wieder neu erfinden.” Die Preisverleihung findet auf der Jahrestagung der “Deutschen Gesellschaft für Computer- und Roboterassistierte Chirurgie” (CURAC) in Düsseldorf statt.”
