Specimen scanned by Matthew Colbert 23 June 2005 in 2 parts (343 and 555 scans), due to scanner crash.. \\r\\n\\r\\n16bit: 1024x1024 16-bit TIFF images. II, 180 kV, 0.133 mA, no filter, empty container wedge, no offset, slice thickness 2 lines (= 0.1108 mm), S.O.D. 173 mm, 1400 views, 2 samples per view, inter-slice spacing 2 lines (= 0.1108 mm), field of reconstruction 56 mm (maximum field of view 56.69273 mm), reconstruction offset 6300, scanner scale 5660, reconstruction scale 1800. Acquired with 15 slices per rotation. Drift correction done based on raw sinogram data using IDL routine “RK_SinoDeDrift” with parameter “driftlength=21.” Reconstructed with beam hardening coefficients 0, 0.85, 0.1 and as follows for each scan set. After sets were merged and matched, overlapping slices 333-345 and blank slices at the end were deleted. Total final slices=870.\\r\\n\\n\\nRelated URL: http://digimorph.org/specimens/Osteolaemus_tetraspis/ Migrated MorphoSource 1 Media Group Description: Related URL: http://digimorph.org/specimens/Osteolaemus_tetraspis/
