DescriptionString: Reconstructed CT slices for skull of Pantodon buchholzi (University of Michigan Museum of Zoology catalog number UMMZ Fish 249782) 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.
MethodString: Specimen UMMZ Fish 249782_Pantodon buchholzi_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, 65 kV, 195 uA; source to object distance, 82.8682289123535 mm; source to detector distance, 1114.153 mm; scanned with 3141 projections; voxel size, x = 0.0148755572279589 mm y = 0.0148755572279589 mm z = 0.0148755572279589 mm; slice dimension (in pixels), x = 1102, y = 1546; number of slices, 1948 16-bit TIFF images. Original floating point grey values were scaled to span the unsigned 16-bit integer range using an offset of 2056.752685546875 and a scale factor of 19.245679718825077, where 16output = SCALE * (32input + OFFSET). Additional metadata can be found in the xtekct, ctprofile.xml, and UMMPCombinedMetadata.json files.
