Giant 3D-printed White Matter-Brain

Für eine Hirn-Ausstellung haben sie ein 60 Zentimeter breites Gehirn auf einem 3D-Drucker ausgegeben, und zwar nur die Weiße Substanz davon. War anscheinend ziemlich kompliziert, da die Datensätze aus dem MRI-Brainscans viel zu komplex für herkömmliche 3D-Printer waren und aufwändig bearbeitet werden mussten.

"The human brain consists of white and gray matter. The white matter of the brain contains fibers that connect gray matter areas of the brain with each other," he said. "Using an MRI scan of a 40-year-old man, we calculated diffusion tensors, and then created the white matter fiber tracts from them. We handed a surface model of the fiber tracts to Direct Dimensions for processing.” […]

And the model was very complex. Each white matter pattern was described as a “strand,” and it had about 2,000 strands in the data. But the apparent beauty created by the complex strands was causing the model to be rejected. […] Ultimately it took weeks of grueling work to prepare this file for APP. “This work required a highly skilled technician with just the right disposition. Without the right human resources, this project would have never happened," said Harry. "With about 2,000 strands to sort through, it was a task of immense proportions. Mind boggling in fact."
