University of Texas High-Resolution X-ray CT Facility Archive 1490 Ekdale: cynoc: Scans of the left petrosal of Cynocephalus volans (AMNH 187859; female, Bo. Patok, Dagami, Mt. Lobi, Leyte, Philippines) for Eric Ekdale of The University of Texas Department of Geological Sciences. Specimen scanned by Matthew Colbert 3 October 2006. 16bit: 1024x1024 16-bit TIFF images. II, 180 kV, 0.13 mA, no filter, no offset, empty container wedge, slice thickness 1 line (= 0.02746 mm), S.O.D. 78 mm, 1800 views, 2 samples per view, inter-slice spacing 1 line (= 0.02746 mm), field of reconstruction 22 mm (maximum field of view 25.97511 mm), reconstruction offset 6000, reconstruction scale 4600, intensity control on. Acquired with 31 slices per rotation and 25 slices per set. Flash- and ring removal processing done by Jessie Maisano based on correction of raw sinogram data using IDL routines “RK_SinoDeSpike” and “RK_SinoRingProcSimul,” both with default parameters. First six duplicate slices of each set deleted. Rotation correction processing done by Jessie Maisano using IDL routine “DoRotationCorrection.” Total final slices = 350.
