  "abstract": "<p><strong>SophiaBeads Dataset</strong>&nbsp;are acquired specifically for testing and comparing reconstruction methods for x-ray computed tomography.&nbsp;The sample is a&nbsp;plastic tube with a diameter of 25mm, filled with uniform&nbsp;Soda-Lime Glass (SiO2-Na2O) beads of diameters 2.5mm (with&nbsp;standard deviation 0.1mm). The sample has been scanned in the same conditions for each dataset, where the number of projections is halved after each batch scan&nbsp;(starting from 2048,&nbsp;down to 64 projections). This allows us to&nbsp;understand the effects of fewer projections, and develop algorithms that deliver quality results when the information content is low&nbsp;(i.e. faster scans or lower dose).&nbsp;</p>\n\n<p>&nbsp;</p>\n\n<p>These dataset&nbsp;are also suitable for developing and/or testing</p>\n\n<ul>\n\t<li>segmentation methods,</li>\n\t<li>image or data&nbsp;correction techniques (e.g. centre of rotation),</li>\n\t<li>forward and back project implementations, and</li>\n\t<li>benchmarking user&rsquo;s own code/method.</li>\n</ul>\n\n<p>&nbsp;</p>\n\n<p>For the reconstruction and quantification examples, please see (will&nbsp;update with link&nbsp;to paper!)</p>\n\n<p>To use&nbsp;these datasets for own research, please follow the technical report available via (, and the GitHub&nbsp;repository ( If publishing work with these datasets, <strong>the reader must cite&nbsp;the dataset&nbsp;<em>and</em> the codes separately</strong>.&nbsp;</p>\n\n<p>&nbsp;</p>\n\n<p>The dataset&nbsp;are taken using the <em>Nikon Custom Bay</em> machine (using a cone-beam geometry), located in the Manchester Xray Imaging Facility (, by Sophia B.
