IEEE VIS 2020: Medical Visualization Highlights

(We are very thankful that Eric Mörth, PhD candidate at the University of Bergen VisGroup and MMIV, could write this report looking forward to the medical visualization-related papers at IEEE VIS 2020 for us!)

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!

As VCBM is held virtually this year due to COVID-19, the registration is free for all participants (visit www.vcbm.org to register). This year, VCBM is held jointly with VMV (the 25th International Symposium on Vision, Modeling and Visualization) and DAGM GCPR (the 42nd German Conference on Pattern Recognition). All talks will be live-streamed and there will be ample opportunities for discussions and scientific exchange.

For the 10th anniversary of EG VCBM, we are happy to announce an exciting program with high-profile keynote speakers, research paper presentations, industry talks, a joint panel discussion together with VMV, a free half-day tutorial on game engines for visualization on Monday, posters, and an image contest. For the latter, we would like to invite you to submit your images related to computational biology and medicine – visualizations, photorealistic and non-photorealistic renderings, computer generated and hand-drawn illustrations are all welcome. A jury will select the best submission to receive the VCBM Image Award, and the conference participants will select the People’s Choice Award. All the accepted submissions will be displayed in a virtual gallery on the VCBM webpage. The deadline for the submission is September 20, 2020. For more information and submission instructions, please visit: https://www.gcpr-vmv-vcbm-2020.uni-tuebingen.de/?page_id=612

Call for Participation: Dirk Bartz Prize for Visual Computing in Medicine 2019

The Eurographics Association organizes a biannual competition to acknowledge the contribution of computer graphics in the medical field, 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 far too early in March 2010. Dirk Bartz was a highly
recognized and enthusiastic scientist, teacher and promoter of Visual Computing in Medicine.

Submissions to the Dirk Bartz Prize for Visual Computing in Medicine 2019 are being invited from researchers and developers who can demonstrate that a particular benefit in a medical application has resulted from the use of visual computing technology that they have produced/developed. Submissions from all areas of visual computing — examples include the use of new data visualization techniques, interaction methods, or virtual/augmented environments are welcome. Entries typically summarize a body of research and/or development that has been conducted over the course of a project, PhD thesis, etc. and particular weight is put on demonstrating the medical impact of the work.

The submission deadline for next year’s award is January 25, 2019. Please find more information on the official webpage.
