Migrated MorphoSource 1 Media Group Title: HRXCT scan Migrated MorphoSource 1 Media File Description: University of Texas High-Resolution X-ray CT Facility Archive 1373 \\r\\n\\r\\nMaisano:\\r\\nArretosaurus: Scans of the skull of Arretosaurus ornatus (AMNH 6706) for Jessie Maisano of The University of Texas at Austin and AToL. Specimen scanned by Richard Ketcham 2 January 2006. \\r\\n \\r\\n16bit: 1024x1024 16-bit TIFF images. II, 180 kV, 0.133 mA, no filter, no offset, empty container wedge, slice thickness 2 lines (= 0.166401 mm), S.O.D. 244 mm, 1000 views, 2 samples per view, inter-slice spacing 2 lines (= 0.166401 mm), field of reconstruction 79 mm (maximum field of view 79.96 mm), reconstruction offset 5000, scanner scale 1000, reconstruction scale 300. Acquired with 15 slices per rotation. Drift removal processing done by Jessie Maisano based on correction of raw sinogram data using IDL routine “RK_SinoDeDrift” with parameter “driftlength=21.” Reconstructed with beam hardening coefficients [0, 0.6, 0.1, 0.05] and rotation of 70 degrees clockwise. Rotation correction processing done using IDL program “DoRotationCorrection.” Total slices = 600.\\r\\n\\n\\nRelated URL: http://digimorph.org/specimens/Arretosaurus_ornatus/ Migrated MorphoSource 1 Media Group Description: Related URL: http://digimorph.org/specimens/Arretosaurus_ornatus/
