Short description
3D surface mesh reconstruction of the fossil human mandible from Banyoles, Spain.
Full description
3D surface mesh reconstruction of the fossil human mandible from Banyoles, Spain. The 3D mesh reconstruction was derived from a CT scan of the original 45 - 66 kya fossil human mandible from Banyoles, Spain. This mandible was CT scanned by the Institut Català de Paleontologia.

STEP 2: IMAGE PROCESSING

Raw private media was processed with 5 activities to create derived Media 000492640: Mandible [Mesh] [CT] (this media).

Processing Details Field Definitions

Creator
Brian A. Keeling
Event date
January 18, 2023
Software
Mimics Medical 20.0
Description
3D surface mesh of the reconstructed fossil human mandible from Banyoles, Spain. 3D mesh was generated from a CT scan of the original fossil and was generated through segmented mask of the travertine, bone, dentine, and enamel tissues. Each of these elements were both automated and manually segmented. Then a 3D mesh was generated for each element (bone, dentine, travertine, enamel). Using mirror-imaging as well as manual and the global alignment function in Mimics Medical 20.0, the mandible was reconstructed. The 3D meshes of each element was combined and then was exported as an '.stl' file format.

Processing Activity 1: Histogram Editing

Software
Mimics Medical 20.0
Description
Adjusting the grayvalue range to reduce noise.

Processing Activity 2: Background Removal and/or Masking

Software
Mimics Medical 20.0
Description
Segmentation of each individual element was required to fully analyze each part and to reveal aspects of the morphology. Elements include the travertine matrix still adhered to the bone, the bone, the dentine, and the enamel. Since automated segmentation was sometimes unable to distinguish some elements from others, some manual segmentation was required.

Processing Activity 3: Reconstructed Tomography to Mesh

Software
Mimics Medical 20.0
Description
Each segmented mask representing each of the elements were subsequently turned into high quality surface meshes.

Processing Activity 4: Reconstruction

Software
Mimics Medical 20.0
Description
Using mirror imaging as well as manual and global alignment, elements that were missing or damaged were reconstructed.

Processing Activity 5: Merge

Software
Mimics Medical 20.0
Description
The 3D meshes were merged after reconstruction and exported as an '.stl' file.
