Specimen scanned by Matthew Colbert 16 November 2004. \\r\\n\\r\\n16bitrot: 1024x1024 16-bit TIFF images. II, 180 kV, 0.133 mA, no filter, empty container wedge, no offset, slice thickness 2 lines (= 0.09457 mm), S.O.D. 138 mm, 1000 views, 2 samples per view, inter-slice spacing 2 lines (= 0.09457 mm), field of reconstruction 44.5 mm (maximum field of view 45.2231 mm), reconstruction offset 5000, reconstruction scale 630. Acquired with 15 slices per rotation. Drift- and ring-removal processing done by Susan Garlock based on correction of raw sinogram data using IDL routines “RK_SinoDeDrift” with parameter “driftlength=11” and “RK_SinoRingProcSimul” with default parameters. Rotation correction processing done by Susan Garlock using IDL routine “DoRotationCorrection”. Total slices = 630.\\r\\n\\n\\nRelated URL: http://www.digimorph.org/specimens/Arundelemys_dardeni/ Migrated MorphoSource 1 Media Group Description: Related URL: http://www.digimorph.org/specimens/Arundelemys_dardeni/
