Scans of a fractured welded tuff by Richard Ketcham at the University of Texas High-Resolution X-ray CT Facility on 20 June 2006. Original data 512x512 16-bit TIFF images. P250D, 419 kV, 1.8 mA, 1 brass filter, air wedge, no offset, slice thickness = 0.25 mm, 32 ms integration time, S.O.D. 575 mm, 2000 views, 1 ray averaged per view, 1 sample per view, inter-slice spacing = 0.25 mm, field of reconstruction 120 mm (maximum field of view 120.85 mm), reconstruction offset 150000, reconstruction scale 3200. Streak- and ring-removal processing done by Richard Ketcham, August 2009, using IDL routines “RK_SinoDeStreak” with default parameters and “RK_SinoRingProcSimul” with parameters “/additive” and “binwidth=21, bestof5=11.” Total slices = 614.
Data cropped t0 400x120 to remove extraneous material, and excess slices 1-5 and 607-614 omitted.
