On 16 April our students attended the workshop «Hands-On Volume Graphics» held by Simon Tschachtli and made possible by Dr. Wolf Schweitzer from the Institute of Forensic Medicine (IRM) at the University of Zurich.
Usually, the institute uses their CT scanner to perform forensic analyses with the Virtopsy technique. This time however, our students had the unique opportunity to bring their own specimens to be scanned in the CT scanner in order to experiment with segmentation and volume rendering.
The results are mesmerizing: By tweaking settings of the density ramp with different colors, not only it was possible to visualize inner structures of the objects, but also to achieve stunning three-dimensional visual effects.
Guess what this specimen is… it’s Kinder Eggs! Visualization: Oliver Bruderer Through 3D segementation it was possible to directly visualize the surprise contents without opening the eggs. We can recognize a figurine of a chameleon! Visualization: Simon Tschachtli
By using everyday objects (with a humorous touch) in a CT scanner our students were able to fully grasp the technique of scientific imaging through 3D scanning techniques. Since data of this type is generated in many scientific and technical applications, the potential is huge. We would like to thank Dr. Wolf Schweitzer and the Institute of Forensic Medicine for enabling us to make use of this opportunity!
