Full description
University of Texas High-Resolution X-ray CT Facility Archive 1536 Snitting: spodi: Scans of a fossil Spodichthys buetleri (P.1662/6708; Famennian; Hogbom Bjerg, East Greenland) for Daniel Snitting and Per Ahlberg of Uppsala University, Physiology and Developmental Biology Department. Specimen scanned by Matthew Colbert 14 November 2006. 16bit: 1024x1024 16-bit TIFF images. II, 180 kV, 0.11 mA, no filter, air wedge, no offset, slice thickness 1 line (= 0.02438 mm), S.O.D. 70 mm, 2000 views, 3 samples per view, inter-slice spacing 1 line (= 0.02438 mm), field of reconstruction 23.19 mm (maximum field of view 23.19984 mm), reconstruction offset 4000, reconstruction scale 2100. Acquired with 31 slices per rotation and 25 slices per set. Flash and ring-removal processing done by Alison Mote based on correction of raw sinogram data using IDL routines “RK_SinoDeSpike” and “RK_SinoRingProcSimul,” both with default parameters. Reconstructed with beam hardening coefficients [0, 0.85, 0.1]. First six duplicate slices of each set deleted except for slices 192, 223 & 254 (added back to the data and renumbered as 151, 177 and 203, respectively, to replace missing slices). Last seven blank slices deleted. Total final slices = 321.
