DescriptionString: 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 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 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. Scans were collected with the following settings: energy settings, 130 kV, 155 uA; source to object distance, 679.399 mm; source to detector distance, 1104.0 mm; scanned with 3141 projections; voxel size, x = 0.1230795 mm y = 0.1230795 mm z = 0.1230795 mm; slice dimension (in pixels), x = 1776, y = 1713; 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 5651.837890625 and a scale factor of 8.921854087692775, where 16output = SCALE * (32input + OFFSET). Additional metadata can be found in the xtekct, ctprofile.xml, and UMMPCombinedMetadata.json files.
