Methodology
  • Specimen UMMP VP 118711_Mammuthus primigenius_tusk block number 2 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, 120 kV, 120 uA; source to object distance, 194.767002105713 mm; source to detector distance, 1105.0 mm; scanned with 3141 projections; voxel size, x = 0.0352519543964051 mm y = 0.0352519543964051 mm z = 0.0352519543964051 mm; slice dimension (in pixels), x = 675, y = 1062; 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 237.018 and a scale factor of 100.821, where 16output = SCALE * (32input + OFFSET). Additional metadata can be found in the xtekct, ctprofile.xml, and UMMPCombinedMetadata.json files.
Description
  • Reconstructed CT slices for tusk block number 2 of Mammuthus primigenius (University of Michigan Museum of Paleontology catalog number UMMP VP 118711) 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.
