Notes
| 1024x1024 16-bit TIFF images. II, 180 kV, 0.22 mA, intensity control off, high-power mode, no filter, empty container wedge, no offset, slice thickness 1 line ( = 0.03205 mm), S.O.D. 92 mm, 2400 views, 2 samples per view, inter-slice spacing 1 line ( = 0.03205 mm), field of reconstruction 30 mm (maximum field of view 30.6 mm), reconstruction offset 5000, scanner scale 2000, reconstruction scale 3400. Acquired with 31 slices per rotation and 25 slices per set. Ring-removal processing done by Julia Holland based on correction of raw sinogram data using IDL routine “RK_SinoRingProcSimul” with parameter “bestof5=11.” Reconstructed with beam hardening coefficients [0, 0.75, 0.1]. Deleted first 6 duplicate slices from each rotation. Post-reconstruction ring correction applied by Julia Holland with parameters “oversample=3, binwidth=11, sectors=60.” Deleted last 6 blank slices. Total final slices = 494. |
