Specimen scanned by Matthew Colbert 15 June 2009. \\r\\n\\r\\n16bitrot: 1024x1024 16-bit TIFF images. II, 210 kV, 0.15 mA, intensity control off, high-power mode, no filter, empty container wedge, no offset, slice thickness 2 lines (= 0.1812 mm), S.O.D. 260 mm, 1000 views, 2 samples per view, inter-slice spacing 2 lines (= 0.1812 mm), field of reconstruction 84 mm (maximum field of view 86.49496 mm), reconstruction offset 6000, scanner scale 6000, reconstruction scale 5000. Acquired with 19 slices per rotation and 15 slices per set. Ring-removal processing done by Jessie Maisano based on correction of raw sinogram data using IDL routine “RK_SinoRingProcSimul” with the parameter “bestof5=11.” Reconstructed with beam hardening coefficients [0, 0.8, 0.1, 0.05]. Deleted first four duplicate slices of each rotation. Rotation correction processing done by Jessie Maisano using IDL Routine “DoRotationCorrection.” Deleted first one and last 17 blank slices. Total final slices = 777.\\r\\n
