Methodology
  • Specimen UMMP VP 9318_Stylemys nebrascensis_skull was scanned with a Nikon XT H 225ST uCT system housed in the Department of Earth and Environmental Sciences at the University of Michigan. Scans were collected with the following settings: energy settings, 105 kV, 175 uA; source to object distance, 118.009 mm; source to detector distance, 1105.0 mm; scanned with 3141 projections; voxel size, x = 0.02135909 mm y = 0.02135909 mm z = 0.02135909 mm; slice dimension (in pixels), x = 1782, y = 1547; number of slices, 2000 16-bit TIFF images. Original floating point grey values were scaled to span the unsigned 16-bit integer range using an offset of 45.7427 and a scale factor of 46.8193, where 16output = SCALE * (32input + OFFSET). Additional metadata can be found in the xtekct, ctprofile.xml, and UMMPCombinedMetadata.json files.
Description
  • Reconstructed CT slices for skull of Stylemys nebrascensis (University of Michigan Museum of Paleontology catalog number UMMP VP 9318) as a series of TIFF images. Raw projections are not included in this dataset. The reconstructed slice data from the scan are offered here as a series of unsigned 16-bit integer TIFF images. The upper left corner of the first image (*_0000.tif) is the XYZ origin.
