Notes
| 1024x1024 16-bit TIFF images. II, 180 kV, 0.133 mA, aluminum filter, air wedge, no offset, slice thickness 1 line (= 0.0091 mm), S.O.D. 26 mm, 1600 views, 4 samples per view, inter-slice spacing 1 line (= 0.0091 mm), field of reconstruction 6.8 mm (maximum field of view 8.520294 mm), reconstruction offset 2780, reconstruction scale 260. Reconstructed off-center: x = -0.6, y = 0.1. Acquired with 27 slices per rotation. Drift- and ring-removal processing done by Rachel Racicot based on correction of raw sinogram data using IDL routines “RK_SinoDeDrift” with parameters “DRIFTLENGTH=21”, and “RK_SinoRingProcSimul” with default parameters. Reconstructed with c-ray offsets ranging from 0.0 at image 1 to 1.75 at image 914, except slices 618-837 which were reconstructed with a c-ray offset of 2.0, using a parameter file. Deleted slices 27, 352, 353, and 432 as they were repeat slices. Total slices = 914. |
