Migrated MorphoSource 1 Media Group Title: HRXCT scan Migrated MorphoSource 1 Media File Description: University of Texas High-Resolution X-ray CT Facility Archive \\r\\n\\r\\nMaisano\\r\\nLachesis: Scans of the head of Lachesis muta (FMNH 31178) for Dr. Jessie Maisano of The University of Texas at Austin and ATOL. Specimen scanned by Richard Ketcham 8 September 2004. \\r\\n\\r\\n16bitrot: 1024x1024 16-bit TIFF images. II, 120 kV, 0.2 mA, no filter, empty container wedge, no offset, slice thickness 2 lines (= 0.11932 mm), S.O.D. 174 mm, 1000 views, 2 samples per view, inter-slice spacing 2 lines (= 0.11932 mm), field of reconstruction 56 mm (maximum field of view 56.96 mm), reconstruction offset 5000, reconstruction scale 1700. Acquired with 15 slices per rotation. Spike removal done by Susan Garlock based on correction of raw sinogram data using IDL routine “RK_SinoDespike Reconstructed with angle reset to -8.4 degrees (originally 171.6). Rotation correction processing done by Susan Garlock using IDL routine “DoRotationCorrection”. Images flipped because sample was mounted head down. Images upside down. Total slices = 660.\\r\\n
