HRXCT scan of coprolite
Full description
University of Texas High-Resolution X-ray CT Facility Archive 1526 Chin: CC-03: Scans of a coprolite labeled CO-3 (NUVF-71; Devon Island; Eidsbotn Graben; Cretaceous; Kanguk Fm.) for Karen Chin of the University of Colorado at Boulder, Department of Geology. Specimen scanned by Matthew Colbert 6 November 2006. 16bitrot: 1024x1024 16-bit TIFF images. II, 180 kV, 0.12 mA, intensity control on, no filter, empty container wedge, no offset, slice thickness 1 line (= 0.07489 mm), S.O.D. 215 mm, 1400 views, 3 samples per view, inter-slice spacing 1 line (= 0.07489 mm), field of reconstruction 70 mm (maximum field of view 71.25666 mm), reconstruction offset 5000, reconstruction scale 2490. Acquired with 31 slices per rotation and 25 slices per set. Ring-removal processing done by Alison Mote based on correction of raw sinogram data using IDL routine “RK_SinoRingProcSimul,” with parameters “binwidth=21, bestof5=11.” Reconstructed with beam hardening coefficients [0, 0.7, 0.25]. The first six slices of each rotation deleted. Total final slices = 1500.
