University of Texas High-Resolution X-ray CT Facility Archive 2794 Russo: Gg167336: Scans of a sacrum of Gorilla gorilla gorilla (AMNH 167336; male, Cameroon), for Gabrielle Russo of UT Anthropology. Specimen scanned by Matthew Colbert 20 and 21 August 2012. Specimen scanned in two parts and matched. 16bitrot: 1024x1024 16-bit TIFF images. II, 200 kV, 0.24 mA, intensity control off, high-power mode, no filter, empty container wedge, no offset, slice thickness 1 line ( = 0.08015 mm), S.O.D. 230 mm, 1800 views, 2 samples per view, inter-slice spacing 1 line ( = 0.08015 mm), field of reconstruction 76.5 mm (maximum field of view 76.51212 mm), reconstruction offset 4000, reconstruction scale 6000. Acquired with 31 slices per rotation and 25 slices per set. Ring-removal processing done by Julia Holland based on correction of raw sinogram using IDL routine “RK_SinoRingProcSimul” with parameters “sectors=100, binwidth=5” (first half) and “bestof5=11, binwidth=5” (second half). Second half reconstructed with rotation = 0.2° CW, X offset = 0.3, and Y offset = -0.25 to match first half. Both halves reconstructed with beam hardening coefficients = [0, 0.85, 0.1]. Deleted first 3 and last 3 duplicate slices from each rotation. Rotation correction processing done by Julia Holland using IDL routine “DoRotationCorrection.” Deleted first 12 and last 3 blank slices. Total final slices = 2235.
