University of Texas High-Resolution X-ray CT Facility Archive 1343 Rowe: odobe: Scans of a baby walrus skull of Odobenus rosmarus divergens (MVZ 63308; Sevoonga, St. Lawrence Island, Alaska; coll. 1931, female) for Tim Rowe and Digimorph of the University of Texas at Austin. Specimen scanned by Philip Watson 4 November 2005. 16bit: 1024x1024 16-bit TIFF images. P250D, 420 kV, 1.8 mA, no filter, air wedge, 160% offset, 32 ms integration time, slice thickness (= 0.25 mm), S.O.D. 641 mm, 1000 views, 1 ray averaged per view, 1 sample per view, inter-slice spacing (= 0.2 mm), field of reconstruction 208 mm (maximum field of view 210.154 mm), reconstruction offset 9300, scanner scale 7200, reconstruction scale 2200. Ring removal processing done by Alison Mote based on correction of raw sinogram data using IDL routine “RK_SinoRingProcSimul” with default parameters. Reconstructed with an angle of 170 degrees. Images were flipped horizontally in Photoshop and then renumbered in reverse order. Total slices = 620.
