Migrated MorphoSource 1 Media Group Title: HRXCT scan Migrated MorphoSource 1 Media File Description: University of Texas High-Resolution X-ray CT Facility Archive 1794\\r\\n\\r\\nHanken:\\r\\nnycti: Scans of the whole body of Nyctixalus pictus (FMNH 242743) for Jim Hanken of Harvard University. Specimen scanned by Matthew Colbert 7 December 2007. Original slices 309-311, 328-331, 442-453, 613-616, 651-653, 765, 860-865, 879-882, 898-902, 917-919, 936-940, and 993-995 were reconstructed three times, one set with a c-ray offset of 0.75, the other with a c-ray offset of -0.75, and the last with no correction. Images were “stitched” together in Photoshop so that the far right side of some images (328-331, 613-616, 651-653, 882) contain the c-ray correction of 0.75, the far left side of some of the images consists of the -0.75 correction (309-311, 442-453, 860-865), and some images contain both a correction of 0.75 on the right side and -0.75 on the left (765, 879-881, 898-902, 917-919, 936-940, 993-995).\\r\\n \\r\\n16bit: 1024x1024 16-bit TIFF images. II, 200 kV, 0.125 mA, intensity control on, high power mode, no filter, empty container wedge, no offset, slice thickness 2 lines (= 0.0431 mm), S.O.D. 62 mm, 1400 views, 3 samples per view, inter-slice spacing 2 lines (= 0.0431 mm), field of reconstruction 18.5 mm (maximum field of view 20.5374 mm), reconstruction offset 5000, reconstruction scale 6000. Acquired with 19 slices per rotation and 15 slices per set. Ring-removal processing done by Rachel Racicot based on correction of raw sinogram data using IDL routine “RK_SinoRingProcSimul” with parameters “binwidth=21, bestof5=11”. Reconstructed with a rotation of 7 degrees. Deleted first four duplicate slices of each rotation. Deleted last 5 slices of entire dataset. Total final slices = 880.\\r\\n\\n\\nRelated URL: http://digimorph.org/specimens/Nyctixalus_pictus/whole/ Migrated MorphoSource 1 Media Group Description: Related URL: http://digimorph.org/specimens/Nyctixalus_pictus/whole/
