University of Texas High-Resolution X-ray CT Facility Archive 3014 Rowe: aetos: Scans of the partial skeleton of an aetosaur (TMM 31100-1336. WPA quarries, Howard County, TX, excavated 1939-1941; Late Triassic) for Timothy Rowe of The University of Texas at Austin. Specimen scanned by Matthew Colbert 20 May 2013. 16bit: 1024x1024 16-bit TIFF images. II, 200 kV, 0.26 mA, intensity control off, high-power mode, no filter, empty container wedge, no offset, slice thickness 1 line ( = 0.07666 mm), S.O.D. 220 mm, 1400 views, 3 samples per view, inter-slice spacing 1 line ( = 0.07666 mm), field of reconstruction 73 mm (maximum field of view 73.18551 mm), reconstruction offset 5000, reconstruction scale 1000. Acquired with 31 slices per rotation and 25 slices per set. Drift-, fillin-, and ring-removal processing done by Julia Holland based on correction of raw sinogram data using IDL routines “RK_SinoDeDrift” with default parameters, “RK_SinoFillin” with parameters “1, /top” (slices 1024-1054), and “RK_SinoRingProcSimul” with parameter “bestof5=11.” Reconstructed with beam-hardening coefficients using IDL Find BHC [Y found = 0.06, 0.30, 0.57, 0.91, 1.25, 1.75, 2.57 with parameters “Num Coef=7, Downsample=4x, ROI mode=Joint, No Mono Function, Fix endpoints, No Exp (non-decreasing) slope, No Destreak]. Deleted first 3 and last 3 duplicate slices from each rotation. Rotation correction processing done by Julia Holland using IDL routine “DoRotationCorrection.” Deleted first 3 and last 13 blank slices. Post-reconstruction ring correction applied by Jessie Maisano using parameters oversample=3, binwidth=21, sectors=60. Total final slices = 1209.
