Specimen scanned by Matthew Colbert 24 January 2005.\\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 (= 0.07572 mm), S.O.D. 110 mm, 1600 views, 2 samples per view, inter-slice spacing 2 lines (= 0.07572 mm), field of reconstruction 31 mm (maximum field of view 36.01216 mm), reconstruction offset 5100, reconstruction scale 1500. Acquired with 15 slices per rotation. Spike- and ring-removal processing done by Susan Garlock based on correction of raw sinogram data using IDL routines “RK_SinoDeSpike” and “RK_SinoRingProcSimul”, both with default parameters. Reconstructed with c-ray offset of +0.5 and reconstruction angle -12 degrees. Rotation correction processing done by Susan Garlock using IDL routine “DoRotationCorrection”. Total slices = 555.\\r\\n
