Migrated MorphoSource 1 Media Group Title: HRXCT scan Migrated MorphoSource 1 Media File Description: University of Texas High-Resolution X-ray CT Facility Archive 1136\\r\\n\\r\\nMaisano:\\r\\n\\r\\nSonora: Scans of the head of Sonora semiannulata (FMNH 26876) for Dr. Jessie Maisano of The University of Texas at Austin and ATOL. Specimen scanned by Richard Ketcham 9 December 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 (= 0.02078 mm), S.O.D. 30.3 mm, 2000 views, 2 samples per view, inter-slice spacing 2 lines (= 0.02078 mm), field of reconstruction 9 mm (maximum field of view 9.92 mm), reconstruction offset 8600, reconstruction scale 1600. 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=21” and “RK_SinoRingProcSimul”, with parameter “binwidth=21”. Reconstructed with C-ray offsets between -0.5 and -1.5, using a parameter file. Rotation correction processing done by Susan Garlock using IDL routine “DoRotationCorrection” and images rotated upright using Photoshop. Original image #16 deleted as it was a duplicate. Total final slices = 614.\\r\\n
