Summary This submission contains a tomographic dataset of a wooden plank. The data is made available as part of [Bossema et al., 2021]. Apparatus The dataset is acquired using the custom-built and highly flexible CT scanner, FleX-ray Laboratory, developed by TESCAN-XRE, located at CWI in Amsterdam. This apparatus consists of a cone-beam microfocus X-ray point source that projects polychromatic X-rays onto a 1944-by-1536 pixels, 14-bit, flat detector panel. Full details can be found in [Coban 2020]. Sample Information The sample is a conifer plank (20mm x 150mm x 230mm). Experimental Plan The data in this submission was collected to compare dendrochronological measurements on the reconstructed image using a linear scanning trajectory and a photograph of the transverse section of the plank on the outside (see Figure 6 in [Bossema et al, 2021]). The projections were acquired using 70kV and 30W tube settings. All raw data (i.e. no corrections) is made available in .tif format. List of Contents The content of the submission is given below. continuous_line_panel: 1875 projections This data folder contains: dark-field (or closed-shutter) image, di000000.tif, flat-field (or open-shutter) image before acquisition, io000000.tif, and after acquisition, io000001.tif, raw (unprocessed or uncorrected) projections, scan_*.tif, scan settings.txt, a text file with scanner metadata in more human readable format, and script_executed.txt, the text file containing the list of commands the apparatus has executed. data settings XRE.txt, a text file with scanner metadata, Acquisition settings XRE, a text file with scanner metadata.
