Full description
University of Texas High-Resolution X-ray CT Facility Archive 1518 Triche: phalacrocorax: Scans of the head of a whole preserved Phalacrocorax penicillatus (TMM M-1180; California, Marin Co.) for Nina Triche of The University of Texas at Austin Department of Geological Sciences. Specimen scanned by Matthew Colbert 31 October 2006. Scanned in two parts phalA (228 slices) and phalB (1426 slices), which overlap by one set. 16bitrot: 1024x1024 16-bit TIFF images. II, 180 kV, 0.13 mA, no filter, empty container wedge, no offset, slice thickness 2 lines (= 0.1149 mm), S.O.D. 165 mm, 1200 views, 2 samples per view, inter-slice spacing 2 lines (= 0.1149 mm), field of reconstruction 50 mm (maximum field of view 54.69 mm), reconstruction offset 5200, reconstruction scale 5200. Acquired with 19 slices per rotation and 15 slices per set. Drift and ring-removal processing done by Alison Mote based on correction of raw sinogram data using IDL routines “RK_SinoDeDrift” with parameters “driftlength=21, goodfile=76” (goodfile from phalA) and “RK_SinoRingProcSimul” with default parameters. The first four duplicate slices of each rotation deleted except for slices 1-4. Rotation correction processing done by Alison Mote using IDL routine “DoRotationCorrection.” Total final slices = 1294.
