Title: CT Data of UMMP VP 3110, Castoroides ohioensis, cranium (merged scans) Open Access Deposited

Methodology
  • Specimen UMMP VP 3110_Castoroides_Cranium was scanned with a Nikon XT H 225ST uCT system housed in the Department of Earth and Environmental Sciences at the University of Michigan. Two scans were conducted, and the resulting volumes were merged using Amira software. The voxel dimensions are x = 0.1230795 mm y = 0.1230795 mm z = 0.1230795 mm; slice dimension (in pixels), x = 2054, y = 1927; number of slices, 3005 16-bit TIFF images. Original floating point grey values were scaled to span the unsigned 16-bit integer range using an offset of 259.8419189453125 and a scale factor of 74.48046063169338, where 16output = SCALE * (32input + OFFSET). Additional metadata can be found with each individual scan deposit.
Description
  • Reconstructed CT slices for Cranium of Castoroides (University of Michigan Museum of Paleontology catalog number UMMP VP 3110) as a series of TIFF images. Raw projections are not included in this dataset. The reconstructed slice data resulting from a merge of two separate scans are offered here as a series of unsigned 16-bit integer TIFF images. There may be slight differences in voxel grey values between the two parts. The upper left corner of the first image (*_0000.tif) is the XYZ origin.
