Full description
University of Texas High-Resolution X-ray CT Facility Archive 2456 Geisler: xiphi: Scans of the left cochlea of Xiphiacetus bossi (USNM 25670) for Jonathan Geisler of the New York College of Osteopathic Medicine. Specimen scanned by Matthew Colbert 25 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 mm (maximum field of view 14.96976 mm), reconstruction offset 5000, reconstruction scale 2800. 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,” “RK_SinoDeStreak” with default parameters, and “RK_SinoRingProcSimul” with parameter “binwidth=21, bestof5=11.” Reconstructed with beam hardening coefficients using IDL FindBHC [Y found= 0.30, 0.06, 0.06, 0.07, 0.07, 0.08, 0.08, 0.09, 0.10, 0.11, 0.13, 0.15, 0.19, 0.25, 0.33, 0.50, 1.78 with parameters “Num Coef=15, Downsample=None, ROI mode=one material, Mono Function, Fix Endpoints, Non-Decreasing Shape”], X offset = 0.5, Y offset = -0.2, 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. Deleted last 117 blank slices. Total final slices = 658. 8bitjpg: 8-bit JPG version of the above images. specimenphotos: JPG images of the specimens.
