University of Texas High-Resolution X-ray CT Facility Archive 1015 Colbert: Hesperaletes: Scans and image processing of the skull of Hesperaletes borineyi (SDSNH 31326; College Blvd, San Diego Co, CA; Uintan, Middle Eocene, Santiago Fm; collected by B.O. Riney) for Dr. Matthew Colbert of the Department of Geological Sciences, The University of Texas at Austin. Specimen scanned by Matthew Colbert 10 April 2004. This specimen was scanned in two passes. Slices 751 to 919 in the final version were slices 16-195 from the second pass. All of the slices from the first pass were rotated in Photoshop by Rachel Racicot and Matthew Colbert to align with the slices from the second pass. Image processing done by Matthew Colbert. 16bitrot: 1024x1024 16-bit TIFF images. II, 180 kV, 0.133 mA, no filter, empty container wedge, no offset, slice thickness 2 lines (= 0.1626 mm), S.O.D. 235 mm, 1600 views, 2 samples per view, inter-slice spacing 2 lines (= 0.1626 mm), field of reconstruction 74 mm (maximum field of view 77.01035 mm), reconstruction offset 6000, reconstruction scale 650. Acquired with 15 slices per rotation. Rotation correction processing done by Rachel Racicot using IDL routine “DoRotationCorrection”. Using Photoshop, slices 130 to 720 were rotated 0.57o clockwise. Total slices = 919.
