We are glad that Dr. Gabriel Mistelbauer, TU Wien accepted the invitation to give a talk in the Medical Technology colloquium. He will talk about “Advanced Vessel Visualization”

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.

We are delighted that our submission “A Survey of Cardiac 4D PC-MRI Data Processing” received the Honorable Mention award at the VCBM 2015 workshop. The survey paper was authored by Benjamin Köhler and was developed in cooperation with Silvia Born, University of Zürich, Roy van Pelt, Philips Heathcare, Eindhoven, as well as Uta Preim of the Municipal Hospital Magdeburg. Furthermore, our submission “Histology-Based Evaluation of Optical Coherence Tomographic Characteristics of the Cerebral Artery Wall via Virtual Inflating” won the best paper award! Sylvia Glaßer’s work is the result of a novel cooperation between the visualization group, the Institute of Neuroradiology and the Institute of Pathology from the University hospital of Magdeburg and the Departments of Medical Engineering and Fluid Dynamics and Technical Flows from the University of Magdeburg. Both papers are invited to be extended as journal publication for the Computer Graphics Forum.

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 Chester, UK.

“Histology-Based Evaluation of Optical Coherence Tomographic Characteristics of the Cerebral Artery Wall via Virtual Inflating” Glaßer, Sylvia; Hoffmann, Thomas; Boese, Axel; Voß, Samuel; Kalinski, Thomas ; Skalej, Martin; Preim, Bernhard.

“Exploration of 3D Medical Image Data for Interventional Radiology using Myoelectric Gesture Control” Hettig, Julian; Mewes, André; Riabikin, Oleksandr; Skalej, Martin; Preim, Bernhard; Hansen, Christian.

“A Survey of Cardiac 4D PC-MRI Data Processing” Köhler, Benjamin; Born, Silvia; van Pelt, Roy; Preim, Uta; Preim, Bernhard.

“Illustrative Multi-volume Rendering for PET/CT Scans” Lawonn, Kai; Smit, Noeska; Preim, Bernhard; Vilanova, Anna.

We are looking forward to it!

Steffen Oeltze-Jafra spends the entire September with the SciVis group headed by Anders Ynnerman at Linköping University. Steffen stays with the group in Norrköping but will also visit the Center for Medical Image Science and Visualization (CMIV) and Claes Lundström in Linköping.

We are happy to announce that we could spearhead and contribute to five papers being presented at this years IEEE VIS.

“3D Regression Heat Map Analysis of Population Study Data” Paul Klemm, Kai Lawonn, Sylvia Glaßer, Uli Niemann, Katrin Hegenscheid, Henry Völzke, Bernhard Preim.

“Occlusion-free Blood Flow Animation with Wall Thickness Visualization” Kai Lawonn, Sylvia Glaßer, Anna Vilanova, Bernhard Preim, Tobias Isenberg.

“Cluster Analysis of Vortical Flow in Simulations of Cerebral Aneurysm Hemodynamics” Steffen Oeltze-Jafra, Juan R. Cebral, Gábor Janiga, Bernhard Preim.

“Glyph-based Comparative Visualization for Diffusion Tensor Fields” Changgong Zhang, Thomas Schultz, Kai Lawonn, Elmar Eisemann, Anna Vilanova.

CG&A paper: “Interactive Visual Analysis of Heterogeneous Cohort Study Data” Paolo Angelelli, Steffen Oeltze, Judit Haász, Cagatay Turkay, Erlend Hodneland, Arvid Lundervold, Astri J. Lundervold, Bernhard Preim, Helwig Hauser

We look forward to the presentations!

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”.

Wolfgang Schoor successfully defended his PhD Thesis on Interactive Visualization and Modification of Digitized Plant Biological Objects.

Kai Lawonn lead a team that prepared for the MICCAI Conference “Illustrative Visualization of Vascular Models for Static 2D Representations” that was conditionally accepted. It is the first MICCAI paper since 2006 and the strongest paper together with Christian Hansen who recently joined as Faculty member for “Computer-Assisted Surgery”. This research extends the previous work of both groups on illustrative visualization and perception-based studies.”

We were notified and are delighted that our tutorial submission “Rejuvenated Medical Visualization – Large-scale, whole-body visualization, visualizing physiology, non-standard imaging and simulations, and cohort studies” (lead by Steffen Oeltze-Jafra) for a half-day tutorial at this year’s IEEE Visualization conference was accepted. Speakers are Anders Ynnerman, Stefan Bruckner and Helwig Hauser.
