AMNH107151-73989: Scans of two snake heads, scanned together, reconstructed separately: Apodora papuana (AMNH R73989; 1637 slices) and Apodora papuana (AMNH107151; Papua New Guinea: Madang: 2 mi NW Alexishafen: m - m. 17 Jul 1969 - 17 Jul 1969. Richard G. Zweifel; 1715 slices) for Damien Esquerre Gheur and Scott Keogh of The Australian National University. Specimens scanned by Matthew Colbert on 22 November 2016.
16bitTIFF: Scan parameters: NSI scanner. Fein Focus High Power source, 170 kV, 0.17 mA, aluminum filter, Perkin Elmer detector, 0.25 pF gain, 1 fps, 1x1 binning, no flip, source to object 270.0 mm, source to detector 1316.827 mm, continuous CT scan, no frames averaged, 0 skip frames, 3600 projections, 6 gain calibrations, 15 mm calibration phantom, data range [-0.5, 10.0] (grayscales adjusted from NSI defaults), beam-hardening correction = 0.1. Specimens repositioned prior to reconstruction.
Images flipped and reordered in ImageJ. Voxel size = 40.4 μm. Total slices = 1715.
