Scanned by Matthew Colbert 20 September 2012.\\r\\n\\r\\n16bit: 1024x1024 16-bit TIFF images. P250D, 450 kV, 3 mA, large spot, 1 brass filter, air wedge, 190% offset, 20 ms integration time, slice thickness = 0.5 mm, S.O.D. 747 mm, 1320 views, 1 ray averaged per view, 1 sample per view, inter-slice spacing = 0.45 mm, field of reconstruction 301 mm (maximum field of view 298.7686 mm. Field of view reported on scan form corresponds to a corrected value after applying a correction of 1.01319%. Field of view used in ACTIS equals 297.0815 mm. Reported maximum field of view reflects uncorrected value), reconstruction offset 5000, reconstruction scale 7000. Ring-removal processing done by Julia Holland based on correction of raw sinogram data using IDL routine “RK_SinoRingProcSimul” with parameter “bestof5=11, binwidth=5.” Total slices = 366.\\r\\n
