A 3D virtual atlas of the head anatomy of Alligator mississippiensis [abstract]
Metadata[+] Show full item record
We present the foundation of an interactive, 3D, web-based anatomical atlas of Alligator cranial anatomy, which includes comparative data from MRI, microMRI, CT, and microCT imaging techniques, supplemented with histology and dissection. The centerpiece of the page is a virtual, “dissectible” Alligator skull where each individual bone can be explored in a 3D environment. One head of a large alligator was CT-scanned and MR imaged, then imported into Amira (v5.1, Visage Imaging) segmentation software. We selected and highlighted individual skull elements using their sutural boundaries and created 3D, integrated, volumetric files. These files were then converted into web-based interactive models using Adobe Acrobat 3D, WireFusion and other software packages.
