Full description
University of Texas High-Resolution X-ray CT Facility Archive 2451 Geisler: zarha: Scans of the left cochlea of Zarhochis flagellator (USNM 10485) for Jonathan Geisler of the New York College of Osteopathic Medicine. Specimen scanned by Matthew Colbert 26 April 2011. 16bit: 1024x1024 16-bit TIFF images. II, 210 kV, 0.17 mA, intensity control off, high-power mode, no filter, air wedge, no offset, slice thickness 1 line ( = 0.01568 mm), S.O.D. 45 mm, 1400 views, 3 samples per view, inter-slice spacing 1 line ( = 0.01568 mm), field of reconstruction 13.8 mm (maximum field of view 14.96976 mm), reconstruction offset 5000, scanner scale 2000, reconstruction scale 1600. Acquired with 31 slices per rotation and 25 slices per set. Drift-, streak- and ring-removal processing done by Satomi Ishihama based on correction of raw sinogram data using IDL routines “RK_SinoDeDrift” with parameter “/hi50, /despike, driftlength=21, goodfile=440”(applied twice), “RK_SinoDeStreak” with default parameters, and “RK_SinoRingProcSimul” with parameter “binwidth=21, bestof5=11.” Reconstructed with beam hardening coefficients using IDL FindBHC [Y found= 0.52, 0.08, 0.09, 0.10, 0.11, 0.13, 0.15, 0.18, 0.23, 0.33, 0.50, 1.93 with parameters “Num Coefs=10, Downsample=None, ROI mode=one material, Mono Function, Fix Endpoints, Non-Decreasing Shape”] and 1402 views. Deleted last 6 duplicate slices from each rotation. Post-reconstruction ring correction applied by Satomi Ishihama using the parameters oversample = 3.0, binwidth =17, sectors = 60. Total final slices = 775.
