Full description
University of Texas High-Resolution X-ray CT Facility Archive 0862 Colbert: Colodon: Scans of the skull of Colodon, a fossil tapir from the White River Group of South Dakota (SDSM 59566; no data) for Dr. Matthew Colbert of the Department of Geological Sciences, The University of Texas at Austin. Specimen scanned by Matthew Colbert 15 March 2003. The plan mode missed four slices (numbers 30, 480, 510, 540), which were reacquired and placed into renumbered stack. Three of these four slices were rotated in Photoshop (slice 30 by 3° counterclockwise, slice 480 by 0.6° counterclockwise, and slice 510 by 0.3° counterclockwise) by Matt Colbert. 16bitrf: 1024x1024 16-bit TIFF images. P250D, 420 kV, 4.7 mA, one brass filter, empty container wedge, no offset, integration time 32 ms, slice thickness 0.5 mm, S.O.D. 607 mm, 1300 views, one ray averaged per view, one sample per view, inter-slice spacing 0.45 mm, field of reconstruction 112 mm (maximum field of view 127.38 mm), reconstruction offset 2500, reconstruction scale 800. Ring-removal processing done by Rachel Racicot based on correction of raw sinogram data using IDL routine “RK_SinoRingProcSimul”, with default parameters. Total slices = 576.
