Oddities Exhibit_Ruby Seadragon

3D Model

Discovered in 2015 by Josefin Stiller, Nerida G. Wilson & Greg W. Rouse

The model was made using micro CT scans conducted at the Cartilage Tissue Engineering laboratory at the University of California San Diego. The specimen was imaged in a Skyscan 1076 (Kontich, Belgium), wrapped in ethanol-soaked gauze, and positioned in a sealed LDPE container. Imaging was conducted at 36 μm isotropic voxel size, applying an electrical potential of 100 kVp and a current of 100 μA, with a 1.0 mm aluminium filter. A beam-hardening correction algorithm was applied during image reconstruction. The reconstructed file size was 1000×1000×5482 pixels (xyz).

DICOM stacks were processed and segmented in Amira v. 5.4 (Visage Imaging, Inc.), and visualized in Maya 2014 service pack 4 (Autodesk, Inc.). X-ray radiographs of all seadragon species were obtained at Scripps Institution of Oceanography.
