Methodology
  • Specimen UMMZ Fish 200167_Petrocephalus simus_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, 55 kV, 195 uA; source to object distance, 69.6444892883301 mm; source to detector distance, 1114.153 mm; scanned with 3141 projections; voxel size, x = 0.0125017826447849 mm y = 0.0125017826447849 mm z = 0.0125017826447849 mm; slice dimension (in pixels), x = 950, y = 1553; 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 4836.82568359375 and a scale factor of 6.5104243873931, 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 Petrocephalus simus (University of Michigan Museum of Zoology catalog number UMMZ Fish 200167) 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.
