Full description
University of Texas High-Resolution X-ray CT Facility Archive 2264 Evans: stego: Scans of a partial skull of Stegoceras validum (ROM 53555; Ornithischia, Pachycephalosauridae; Upper Cretaceous, Campanian; Belly River Group, Dinasaur Park Fm?; Red Deer River, near Dinosaur Provincial Park) for David Evans of the Royal Ontario Museum. Specimen scanned by Matthew Colbert 13 May 2010. 16bit: 1024x1024 16-bit TIFF images. P250D, 450 kV, 1.3 mA, small spot size, 1 brass filter, air wedge, 190% offset, integration time 32 ms, slice thickness = 0.25 mm, S.O.D. 585 mm, 1600 views, 1 ray per view, 1 sample per view, inter-slice spacing = 0.23 mm, field of reconstruction 232.6705 mm (maximum field of view 236.1214 mm. Field of view reported on scan form corresponds to a corrected value after applying a correction of 1.010942%. Field of view used in ACTIS equals 230.1522 mm. Reported maximum field of view reflects uncorrected value. This scan was originally archived with an incorrectly reported field of view, which was corrected in August, 2010.), reconstruction offset 5800, reconstruction scale 6000. Streak- and ring-removal processing done by Satomi Ishihama based on correction of raw sinogram data using IDL routines “RK_SinoDeStreak” with parameter “cutoff=0.08” and “RK_SinoRingProcSimul” with parameters “bestof5=11” (applied to some slices) and “nuke_INDs=[453-455, 519-521]” (applied to slices 208, 259-264). Reconstructed with rotation angle = 3 degrees. Post-reconstruction ring correction done by Satomi Ishihama using UTCT ring correction program with the parameters “oversample=3.0, binwidth=19, sectors=60” for slices 208, 259-264, and with parameters “oversample=3.0, binwidth=23, sectors=1” for select slices. Total final slices = 376.
