Nano CT

 Nano CT scan on a pinecone

The internal structure of a pinecone can be resolved clearly by Nano CT, which indicates that there are voids and long fiberlike structure inside the pinecone.

 3D rendering and FE meshing based on Nano CT image

Any 3D image obtained from Nano CT scan can be rendered and meshed for further analysis. The below figures show a rendering and meshing example done on the pinecone image above.
