IMAGE ACQUISITION AND PROCESSING IN DETAIL

Description
Gogodipterus paddyensis was scanned using X-ray micro-computed tomography (X-ray µCT) at the Centre for Microscopy, Characterisation and Analysis (CMCA) at The University of Western Australia (UWA) in Perth, Australia in 2019. Parameters used were 80kV and 7W using a Versa 520 XRM (Zeiss, Pleasanton, CA, USA). An LE2 beam filter was used to mitigate beam hardening and increase contrast. Source-sample and sample-detector distances were set to -73 and 48 mm, respectively, which together with the 0.4X objective and 2x camera binning, resulted in a final pixel resolution of 41.52 µm. Suitable image intensity was achieved with an exposure of 1 s and a total of 2401 projections were collected through 360o for the tomography. Owing to its large size, the sample was scanned in wide stitch mode, with five vertical segments needed to cover the full height. In addition, auto referencing was disabled, with a single reference collection captured prior to scanning. Reconstruction and stitching were achieved automatically by the software using default settings. Total scan time was 21h 38 min.
