University of Texas High-Resolution X-ray CT Facility Archive 2651 Bhullar: hesp_box3: Scans of the dentary of Hesperornis (KUVP 71012) for Anjan Bhullar of Harvard University. Specimen scanned by Matthew Colbert 9 & 10 January 2012. Scanned element from box 3 in photo. Specimen scanned in two halves and matched. Images are cropped from 1024x1024 pixel slices. 16bitrot: 1024x1024 16-bit TIFF images. II, 200 kV, 0.22 mA, intensity control off, high-power mode, no filter, empty container wedge, no offset, slice thickness 1 line ( = 0.04702 mm), S.O.D. 135 mm, 1400 views, 2 samples per view, inter-slice spacing 1 line ( = 0.04702 mm), field of reconstruction 44 mm, (maximum field of view 44.90929 mm), reconstruction offset 5000, reconstruction scale 3000. Acquired with 31 slices per rotation and 25 slices per set. First half of scan: Fillin- and drift-removal processing done by Julia Holland based on correction of raw sinogram data using IDL routines “RK_SinoFillIn” with default parameters for slices 683-713 and parameter “1, /top” for slices 714-744, 1148-1178, and 1737-1767 and “RK_SinoDeDrift” with default parameters. 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 blank slices. Total final slices = 1987. Second half of scan: Fillin- and drift-removal processing done by Julia Holland based on correction of raw sinogram data using IDL routines “RK_SinoFillIn” with parameter “1, /top” for slices 1-31 and 1148-1178, and “RK_SinoDeDrift” with parameter “goodfile=1” using first slice from first half as the good file. Reconstructed with rotation = 35.7° CW, X offset = -0.9, Y offset = 0.71 to match first half. Deleted first 3 and last 3 duplicate slices from each rotation. Rotation correction processing done by Julia Holland using IDL routine “DoRotationCorrection.” Total final slices = 1825. Second half matched to slice number 1999 of first half. Total final slices = 3812.
