Full description
University of Texas High-Resolution X-ray CT Facility Archive 2290 Evans: stegD: Scans of the fossil skull cap of Stegoceras validum (TMP 99.62.1; Ornithischia, Pachycephalosauridae; Upper Cretaceous; Belly River Group, Dinosaur Park Fm; Alberta, Irvine) for David Evans of the Royal Ontario Museum. Specimen scanned by Jessie Maisano 25 June 2010. 16bitrot: 1024x1024 16-bit TIFF images. II, 200 kV, 0.18 mA, intensity control off, high-power mode, no filter, empty container wedge, no offset, slice thickness 1 line ( = 0.08602 mm), S.O.D. 247 mm, 1400 views, 2 samples per view, inter-slice spacing 1 line ( = 0.08602 mm), field of reconstruction 82 mm (maximum field of view 82.16 mm), reconstruction offset 3000, scanner scale 5400, reconstruction scale 7000. Acquired with 31 slices per rotation and 25 slices per set. Fillin-, streak-, drift- and ring-removal processing done by Satomi Ishihama based on correction of raw sinogram data using IDL routines “RK_SinoFillin” with parameters “100, /top” (for slices 838-868) and “115, /top” (for slices 1365-1395), “RK_SinoDeStreak” with parameter “cutoff=0.07,” “RK_SinoDeDrift” with default parameters and “RK_SinoRingProcSimul” with parameters “binwidth=21, bestof5=11.” Reconstructed with rotation angle=-24.1 degrees (for slices 844-1364), -29.2 degrees (for slices 1371-1612), and beam-hardening coefficients using IDL FindBHC [Y found=-0.06, 0.06, 0.16, 0.28, 0.41, 0.55, 0.71, 0.90, 1.15, 1.59 with parameters “Num Coef=10, Downsample=none, ROI mode=bi-joint”]. Deleted first 6 duplicate slices from each rotation. Rotation correction processing done by Satomi Ishihama using IDL routine “DoRotationCorrection.” Post-reconstruction ring correction applied by Satomi Ishihama using the parameters oversample = 3.0, binwidth = 17 or 21, sectors =1 or 60, smoothing = median or mean for selected slices over the gray scale range 1280-65535. Deleted first 7 and last 21 blank slices. Total final slices = 1272.
