Full description
University of Texas High-Resolution X-ray CT Facility Archive 1402 Rowe: Callorhinus: Scans of the skull of Callorhinus ursinus (MVZ 175109; Marina, Monterey Co., CA; coll. 14 Nov. 1973 by L. Thomsen; sex unknown) for Timothy Rowe and Digimorph of The University of Texas at Austin. Specimen scanned by Matthew Colbert on 22 February 2006. Scanned in horizontal orientation. 16bitrot: 1024x1024 16-bit TIFF images. P250D, 420 kV, 1.8 mA, 1 brass filter, air wedge, 160% offset, 0.32 ms integration time, slice thickness = 0.25 mm, S.O.D. 579 mm, 1000 views, 1 ray averaged per view, 1 sample per view, inter-slice spacing = 0.22 mm, field of reconstruction 189.3 mm (maximum field of view 189.3492 mm), reconstruction offset 6300, reconstruction scale 8400. IDL routine “RK_SinoFillIn” with parameter “/border” was used to remove blurring resulting from specimen coming close to the edge of the field of view. Total slices = 401.
