Full description
University of Texas High-Resolution X-ray CT Facility Archive 0369 Rowe: platypus: Warp corrected scans of an adult duck-billed platypus skull (Ornithorhynchus anatinus; AMNH 200255, no data) for Dr. Timothy Rowe, Department of Geological Sciences, University of Texas. Scanned by Matthew Colbert on 9/06/2000. Image processing by Farrah Welch; movies archived on a later disc. Original scan on Archive 0276. Warp corrections applied by Holly Nance, April 2001. Original scan parameters. II, 150 kV, 0.16 mA, no filter, air wedge, 160% offset, slice thickness 4 lines (= 0.21 mm), S.O.D. 90 mm, 1800 views, 2 samples per view, interslice spacing 4 lines (=0.21 mm), field of reconstruction 43.5 mm (maximum field of view 45.68 mm), reconstruction offset 445, reconstruction scale 26. Scanned in three-slice mode. warpcorr (16bit): The above images modified with IDL software “Unwarp v.1.0” written by Dr. Richard Ketcham to correct for radial distortion of images introduced by ACTIS scanning software. The corrected images are now 522 pixels by 522 pixels, resulting in a revised field of reconstruction of 44.350 mm.
