Migrated MorphoSource 1 Media Group Title: HRXCT scan Migrated MorphoSource 1 Media File Description: University of Texas High-Resolution X-ray CT Facility Archive 1127\\r\\n\\r\\nMaisano\\r\\n\\r\\nVaranus: Scans of the head of Varanus exanthematicus exanthematicus (FMNH 58299) for Dr. Jessie Maisano of The University of Texas at Austin and ATOL. Specimen scanned by Richard Ketcham 15 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 (= 0.11855 mm), S.O.D. 173 mm, 1000 views, 2 samples per view, inter-slice spacing 2 lines (= 0.11855 mm), field of reconstruction 54 mm (maximum field of view 56.69 mm), reconstruction offset 5000, reconstruction scale 1800. 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 parameters “binwidth=21” and “bestof5=11”. Reconstruction angle -3.1 degrees. Rotation correction processing done by Susan Garlock using IDL routine “DoRotationCorrection”. Total slices = 930.\\r\\n
