DescriptionString: Reconstructed CT slices for tooth in bone fragment of Colognathus obscurus (University of Michigan Museum of Paleontology catalog number UMMP 7506) 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 UMMP 7506_Colognathus obscurus_tooth in bone fragment 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, 185 kV, 92 uA; source to object distance, 69.9867 mm; source to detector distance, 804.0002 mm; scanned with 1800 projections; voxel size, x = 0.01740962 mm y = 0.01740962 mm z = 0.01740962 mm; slice dimension (in pixels), x = 546, y = 1012; number of slices, 1682 16-bit TIFF images. Original floating point grey values were scaled to span the unsigned 16-bit integer range using an offset of 90.51985931396484 and a scale factor of 99.6174974030145, where 16output = SCALE * (32input + OFFSET). Additional metadata can be found in the xtekct, ctprofile.xml, and UMMPCombinedMetadata.json files.
