Currently, VRVis in Austria, is looking to fill several exciting positions in medical visualization. VRVis is Austria’s leading research center in the field of visual computing focusing on innovative application-oriented research and development projects. They are currently hiring:
We have received word from award co-chairs Steffen Oeltze Jaffra and Renata Raidou that the call for submissions for the Dirk Bartz Prize has been released!
“The Eurographics Association organizes a biannual competition, to acknowledge the contribution of computer graphics and visualization techniques in medicine and life sciences, and to encourage further development. Originally called “Eurographics Medical Prize”, the competition was renamed to “Dirk Bartz Prize for Visual Computing in Medicine” in 2010—in honor of Dirk Bartz, who passed away in March 2010. Dirk Bartz was a highly recognized and enthusiastic scientist, teacher, and promoter of Visual Computing in Medicine; furthermore, he was an active member of the Eurographics Association, and Chair of the EG Medical Prize, in 2007 and 2009. Before, the prize was co-located with the Eurographics Conference. Since this year, it will be co-located with EuroVis and it is broadened to include contributions in life sciences.
Submissions to the Dirk Bartz Prize for Visual Computing in Medicine and Life Sciences 2021 are being invited from researchers and developers, who can demonstrate that a particular benefit in a medical/life sciences application has resulted from the use of visual computing technology that they have produced/developed. We welcome submissions from all areas of visual computing—examples include the use of new data visualization techniques, interaction methods, or virtual/augmented environments. Entries typically summarize a body of research and/or development that has been conducted over the course of a project, PhD thesis, etc. and weight is put on demonstrating the medical/life sciences impact of the work.”
It is this time of the year again. The biggest visualization conference is happening again, and we are all very excited about it. This year VIS is completely virtual which comes with its challenges! For me, one positive side of it is the new VIS2020 virtual webpage. All papers are nicely presented, and it is quite easy to find the papers you are interested in. Nevertheless, I still have the feeling that I would miss something if I don’t go through all the papers and mark the papers which are about medical visualization. This year I thought instead of making a schedule of all medical visualization papers only for myself, I am sharing my schedule with you, so you can enjoy all the great works of the authors as well! I hope to see you all in the Discord channels discussing the awesome papers!
The authors present a workflow called Anatomical Edutainer, which enables the easy, accessible, and affordable generation of physicalizing for tangible, interactive anatomical edutainment. They use 2D printable and 3D foldable physicalizations which change their visual properties under colored lenses or colored lights.
Visualizing Machine Learning:
Explainable Spatial Clustering: Leveraging Spatial Data in Radiation Oncology
Andrew Wentzel, Guadalupe Canahuate, Lisanne van Dijk, Abdallah Mohamed, Clifton David Fuller, G. Elisabeta Marai
The authors deliver a set of lessons learned for creating visual and explainable spatial clustering for clinical users. Their insights were gathered from multi-years collaboration with radiation oncologists and statisticians.
The authors present PRAGMA, an interactive visualization method that allows domain experts to derive scan-specific parcellations from established atlases. PRAGMA features a hierarchical clustering scheme for defining temporally correlated parcels in varying granularity. The visualization supports the user in deciding on how to perform the clustering. The authors assessed the effectiveness of PRAGMA through a user study with four neuroimaging domain experts.
