SophiaBeads Dataset Project

The sample is a plastic tube with a diameter of 25mm, filled with uniform Soda-Lime Glass (SiO2-Na2O) beads of diameters 2.5mm (with 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 (starting from 2048, down to 64 projections).

This allows us to understand the effects of fewer projections, and develop algorithms that deliver quality results when the information content is low (i.e. faster scans or lower dose). These dataset are also suitable for developing and/or testing segmentation methods, image or data correction techniques (e.g. centre of rotation), forward and back project implementations, and benchmarking user’s own code/method. For the reconstruction and quantification examples, please see (will update with link to paper!) To use these datasets for own research, please follow the technical report available via (eprints.ma.man.ac.uk/2290/), and the GitHub repository (sophilyplum.github.io/sophiabeads-datasets/).
